    BARBARA MILANO KEENAN, Circuit Judge:
    Amy    Sharp       appeals          from     the    district      court’s      judgment
    upholding       a    decision       of    the     Social      Security     Administration
    (Social Security), which denied her application for disability
    insurance benefits.             Citing our decision in Mascio v. Colvin,
    
    780 F.3d 632
     (4th Cir. 2015), Sharp primarily argues that the
    Administrative         Law    Judge       (ALJ)      committed     reversible      error    in
    using     his       assessment       of    her       residual      functional       capacity
    (residual       capacity)      when       evaluating        her    credibility      and    the
    opinion of her treating physician.
    Upon our review, we conclude that although the ALJ erred in
    certain    aspects      of     his     analysis,        those     errors    were    harmless
    because     (1)       the     ALJ     sufficiently           explained      his     decision
    regarding       the    weight        he    accorded         the    treating     physician’s
    opinion,    and       (2)     substantial            evidence      supported      the   ALJ’s
    credibility determination.                 Accordingly, we affirm the district
    court’s judgment.
    I.
    We begin by describing the five-step sequential evaluation
    required    by       regulation      that       an    ALJ   must    use    in   determining
    whether a claimant is disabled.                      See 
    20 C.F.R. § 404.1520
    (a)(4).
    The ALJ must assess whether: (1) the claimant has been engaged
    in   “substantial            gainful       activity”;        (2)     the    claimant       has
    3
    impairments      that    meet    the    regulations’         severity        and   duration
    requirements; (3) the impairments meet or equal an enumerated
    impairment;      (4) the       claimant       is    unable   to    perform         her   past
    relevant work; and (5) the claimant can perform other work, if
    she cannot perform her past relevant work.                        
    Id.
          Between steps
    three   and    four,    the     ALJ    must    assess      the    claimant’s       residual
    capacity, or “the most” the claimant can do in a work setting
    despite her limitations.              
    Id.
     §§ 404.1545(a)(1), 404.1520(a)(4).
    The claimant bears the burden of proof through step four, after
    which   the    burden     shifts       to     the   Commissioner        of    the     Social
    Security      Administration          (Commissioner)         to    prove      step       five.
    Mascio, 780 F.3d at 635; Radford v. Colvin, 
    734 F.3d 288
    , 291
    (4th Cir. 2013).
    If, at step one, the ALJ finds that the claimant has been
    working    or,   at     step    two,    finds       that   the    claimant’s         medical
    impairments do not meet the severity and duration requirements,
    the ALJ must conclude that the claimant is not disabled.                                   
    20 C.F.R. § 404.1520
    (a)(4)(i)-(ii).                   However, if the claimant meets
    her burden at these first two steps, the ALJ considers step
    three, and either finds that the claimant is disabled because
    her impairment meets or equals an enumerated impairment, or the
    ALJ moves on to consider step four.                    
    Id.
     § 404.1520(a)(4)(iii).
    In step four, if a claimant can perform her past work given her
    residual capacity, the ALJ will conclude that the claimant is
    4
    not   disabled.          Id.    §§    404.1520(a)(4)(iv),           404.1545(a)(5)(i).
    Otherwise, the ALJ proceeds to step five, which requires that
    the Commissioner prove that the claimant can perform work that
    “exists in significant numbers in the national economy,” and
    therefore        is       not        disabled.              Id.     §§ 404.1560(c)(2),
    404.1520(a)(4)(v).
    In the present case, the ALJ concluded that Sharp did not
    meet her burden at step four regarding her ability to perform
    her past work.          As we explain in detail below, the present case
    concerns      the      ALJ’s    erroneous      use     of    his    residual      capacity
    determination in evaluating Sharp’s credibility and the opinion
    of her treating physician.
    II.
    Sharp      was    diagnosed       with       fibromyalgia     between      2004   and
    2005.       In      September        2006,     she    began       seeing   Dr.     Charles
    Gibellato, a physician who is board-certified in the fields of
    physical    medicine       and    rehabilitation.             Dr.   Gibellato      treated
    Sharp multiple times per year for a period exceeding five years,
    until May 2012.
    In March 2010, Sharp, then thirty-nine years old, filed a
    “protective”        application        for     disability         insurance      benefits,
    alleging an onset date of September 12, 2008, which she later
    amended to July 29, 2010.               Sharp asserted that she was disabled
    5
    due to fibromyalgia, chronic fatigue, chronic lower back pain,
    and irritable bowel syndrome.
    Sharp presented her claim in a hearing before the ALJ in
    September 2012.      She testified that she had widespread pain from
    her upper shoulders to her neck, lower spine, and hips, and
    behind her legs to her knees.             She stated that her pain was
    unpredictable, and that its location and intensity varied.
    Dr. Gibellato’s notes indicated that between October 2010
    and May 2012, Sharp’s symptoms were alleviated by medications
    and injections, but were aggravated by stress and activity.               Dr.
    Gibellato’s notes also reflected that, between October 2010 and
    May 2012, Sharp reported: (1) that on a ten-point scale, her
    monthly average pain level ranged between six and eight, and (2)
    that in the twenty-four hour period prior to her appointments
    with Dr. Gibellato, she generally had achieved between seventy
    percent   and   eighty   percent   relief   of   her   symptoms,   with   one
    instance in which she reported fifty percent relief.
    In   December    2010,   Sharp   completed    a   report   for   Social
    Security in which she stated that on “bad days,” she experienced
    high pain levels that prevented her from attempting household
    activities.     She also related that on bad days, she needed a
    cane to get to the bathroom to use the toilet, and that she
    could not do much more on such days.         Sharp could feed and dress
    herself, and on “good days,” she could perform light household
    6
    chores,    help   her    son    with   homework,       prepare       meals,    shop    for
    groceries, and walk outside with her dogs.                     According to Sharp,
    she had four or five good days each month.
    Dr. Gibellato referred Sharp to Dr. Jennifer Wartella, a
    licensed    clinical     psychologist,         to    receive       treatment   for     the
    psychological     distress       Sharp    experienced         in    relation     to    her
    chronic    pain   and    depression.          Dr.    Wartella       treated    Sharp    in
    September     2011,      and      recorded          that     Sharp     “tend[ed]        to
    catastrophize her pain.”
    After Sharp attended a session with a physical therapist in
    February    2012,     the      therapist’s      notes      indicated      that    Sharp
    demonstrated good potential for rehabilitation.                        The therapist
    recommended a treatment plan that included home exercise, heat,
    and ice.     In August 2012, a different physical therapist noted
    that   Sharp’s    pain      levels     increased       moderately       throughout      a
    sixty-minute      physical       performance         test,     and     recommended       a
    walking     program      or     that     she    engage        in     stretching        and
    conditioning.
    In a recorded statement in June 2012, Dr. Gibellato opined
    that in a work environment, Sharp would need to be able to take
    breaks, to change her position frequently, and to take narcotic
    medications while working.               According to Dr. Gibellato, Sharp
    could not work in a cold environment, and could only perform
    work that involved a low level of stress.                       In September 2012,
    7
    Dr.   Gibellato    further     stated      that    while     Sharp    could    perform
    sedentary     work,    it    was   unlikely       that    she   could    maintain   a
    routine schedule.        He explained that her symptoms would increase
    and have a cumulative effect over time, requiring her to be
    absent from her job after working for between two and four days.
    Upon    considering      this   evidence,        the   ALJ     concluded   that
    Sharp   suffered      from    fibromyalgia,       degenerative        disc    disease,
    degenerative joint disease, obesity, and depression.                          The ALJ
    further      concluded      that   Sharp       could     perform     sedentary    work
    subject to certain limitations.                  The ALJ reasoned that while
    Sharp’s impairments were severe, they did not preclude her from
    performing “all sustained gainful activity.”                    The ALJ’s residual
    capacity assessment stated that Sharp
    was limited to lifting and/or carrying 5 pounds
    frequently, and 10 pounds occasionally, sitting six
    hours in an eight hour workday, and standing/walking
    two hours in an eight hour work day.    [Sharp] had to
    avoid jobs that required production quotas, and
    involved more than occasional overhead work . . . .
    Sharp was limited to work that allowed her to change
    positions once an hour, and work in an inside
    environment . . . . She was also limited to occasional
    interaction with peers, supervisors, and the public,
    and she was allowed to be absent from work about 10
    days a year.
    Because the ALJ concluded that Sharp could perform her past work
    as a payroll clerk, the ALJ held that she was not disabled
    during the relevant time period.
    8
    In    making        this    determination,              the     ALJ    accorded       little
    weight to Dr. Gibellato’s opinion that Sharp could not maintain
    a routine schedule.              The ALJ concluded that Sharp’s “reported
    limitations       were     not    supported            by    [Dr.     Gibellato’s]         office
    notes,     nor     were    they        consistent           with”    the     ALJ’s       residual
    capacity    assessment.               The    ALJ       also       concluded       that    Sharp’s
    impairments reasonably could be expected to cause her alleged
    symptoms,    but     that       her    “statements           concerning       the       intensity,
    persistence and limiting effects of [her] symptoms [we]re not
    credible,” in part because they were inconsistent with the ALJ’s
    residual    capacity        determination.                  The    ALJ     also    stated      that
    Sharp’s ability to function was not limited to the degree Sharp
    alleged because: (1) her subjective complaints were “not fully
    supported     by    the     objective         medical         evidence”;          (2)    she    had
    received “conservative” medical treatment; and (3) her admitted
    activities of daily living diminished her credibility regarding
    the frequency, severity, and limiting effects of her symptoms.
    After the Appeals Council denied Sharp’s request for review
    of the ALJ’s decision, Sharp filed a complaint in the district
    court     seeking     review          of    the       Commissioner’s         final       decision
    denying     her     request           for    benefits.               A     magistrate          judge
    recommended       that    the     district        court       deny       Sharp’s    motion      for
    summary judgment, grant the Commissioner’s motion for summary
    judgment, and affirm the ALJ’s final decision denying Sharp’s
    9
    application for disability benefits.                   The district court adopted
    the magistrate judge’s report and recommendation, and upheld the
    Commissioner’s determination.               This appeal followed.
    III.
    A.
    We first state the well-established standards governing our
    review of disability determinations.                    We must uphold the ALJ’s
    disability determination unless it was based on legal error or,
    in    light   of    the    whole   record,        is   unsupported     by   substantial
    evidence.       
    42 U.S.C. § 405
    (g); Mascio, 780 F.3d at 634 (citation
    omitted); Meyer v. Astrue, 
    662 F.3d 700
    , 704 (4th Cir. 2011).
    The    substantial          evidence    standard         requires      more     than   a
    scintilla, but may be less than a preponderance, of evidence.
    Hancock v. Astrue, 
    667 F.3d 470
    , 472 (4th Cir. 2012).                         We do not
    “reweigh conflicting evidence, make credibility determinations,
    or substitute our judgment for that of the [ALJ].”                          Johnson v.
    Barnhart,       
    434 F.3d 650
    ,    653    (4th      Cir.   2005)    (per    curiam)
    (alteration in original) (citation omitted).                        When conflicting
    evidence could lead reasonable minds to differ regarding whether
    a    claimant      is     disabled,    we    defer      to   the   ALJ’s      disability
    determination.          Hancock, 667 F.3d at 472 (citation omitted).
    10
    B.
    Sharp     contends       that     the       ALJ    applied       incorrect     legal
    standards       (1)   in    evaluating         the       weight    to    be   given     Dr.
    Gibellato’s opinion; and (2) in assessing Sharp’s credibility.
    Sharp argues that these errors were not harmless and require
    reversal of the ALJ’s disability determination.
    1.
    Relying on our decision in Mascio, Sharp contends that the
    ALJ committed reversible error by according little weight to Dr.
    Gibellato’s opinion on the ground that the opinion conflicted
    with the ALJ’s residual capacity determination.                            In advancing
    this argument, Sharp acknowledges that the ALJ provided a second
    reason for assigning little weight to Dr. Gibellato’s opinion,
    namely, that Sharp’s “reported limitations were not supported by
    [Dr. Gibellato’s] office notes.”                    However, Sharp contends that
    this   explanation         is   merely        conclusory     in     nature,    does     not
    provide     a    sufficient          basis    on    which    to     uphold    the     ALJ’s
    decision, and, because of its absence of detail, prevents us
    from engaging in meaningful appellate review.
    In addressing this issue, we first observe that an ALJ must
    accord    controlling       weight       to    a    treating      physician’s       medical
    opinion regarding a claimant’s ability to work, if that opinion
    “is    well-supported           by     medically         acceptable       clinical      and
    laboratory diagnostic techniques and is not inconsistent with
    11
    the   other       substantial          evidence”        in    the    record.            
    20 C.F.R. § 404.1527
    (c)(2); Mastro v. Apfel, 
    270 F.3d 171
    , 178 (4th Cir.
    2001); see 
    20 C.F.R. § 404.1527
    (a)(2).                               Thus, “[b]y negative
    implication,           if   a    physician’s           opinion      is    not        supported    by
    clinical      evidence           or     if     it      is     inconsistent            with    other
    substantial evidence, it should be accorded significantly less
    weight.”      Craig v. Chater, 
    76 F.3d 585
    , 590 (4th Cir. 1996); see
    generally 
    20 C.F.R. § 404.1527
    (c).                           Ultimately, the ALJ is not
    bound   by    a     treating          physician’s        opinion      that       a    claimant     is
    disabled      or       unable     to    work,       because      that      determination          is
    reserved for the ALJ.              See 
    20 C.F.R. § 404.1527
    (d)(1).
    We agree with Sharp that the ALJ committed legal error in
    his analysis of the weight to be accorded to Dr. Gibellato’s
    opinion.      As we have noted, the ALJ used his residual capacity
    assessment        as    one     basis       for   assigning         little       weight      to   Dr.
    Gibellato’s opinion.               We examined a similar analytical error in
    Mascio.      The ALJ in that case had concluded that “the claimant’s
    statements        concerning          the    intensity,       persistence            and   limiting
    effects      of     [the        claimant’s]         symptoms        [we]re       not       credible”
    because      they      were      inconsistent          with    the       ALJ’s       own   residual
    capacity assessment.              Mascio, 780 F.3d at 639.
    We explained in Mascio that the ALJ’s reasoning conflicted
    with the agency’s regulations.                         Id.    Those regulations require
    that an ALJ consider a claimant’s credibility before determining
    12
    her    residual        capacity,        instead       of     permitting          the        ALJ’s
    determination         of    residual       capacity    to    serve    as     a    basis       for
    rejecting a claimant’s credibility.                   Id.
    The ALJ in the present case similarly erred by concluding
    that Dr. Gibellato’s opinion merited little weight because it
    was inconsistent with the ALJ’s assessment of Sharp’s residual
    capacity.         The       regulations        direct       that     an    ALJ        evaluate
    statements from treating physicians before, rather than after,
    determining       a        claimant’s       residual        capacity.            
    20 C.F.R. § 404.1545
    (a)(3).            Thus, the regulations do not allow an ALJ to
    consider whether a treating physician’s opinion is consistent
    with   the   ALJ’s         residual    capacity       assessment      when       determining
    what   weight     to       accord     that    physician’s          opinion.           See     
    id.
    § 404.1527(c)(2).
    We further explained in Mascio, however, that an error of
    this nature may be deemed harmless when the ALJ has provided a
    sufficient      alternate          basis     for   his      negative       assessment          of
    particular evidence.               Mascio, 780 F.3d at 639.                Therefore, we
    must   now   consider        the    sufficiency       of    the    ALJ’s     other      stated
    reason for according less weight to Dr. Gibellato’s opinion.
    When, as here, an ALJ denies a claimant’s application, the
    ALJ must state “specific reasons for the weight given to the
    treating source’s medical opinion,” to enable reviewing bodies
    to identify clearly the reasons for the ALJ’s decision.                                 Social
    13
    Security Ruling (SSR) 96-2p, 
    61 Fed. Reg. 34,490
    , 34,492 (July
    2, 1996).      Based on our review of the record before us, we
    conclude that the ALJ provided a second, specific reason that is
    sufficient to afford such appellate review.
    The ALJ did not summarily conclude that Dr. Gibellato’s
    opinion merited little weight.                  Cf. Monroe v. Colvin, 
    826 F.3d 176
    , 190-91 (4th Cir. 2016) (holding ALJ’s statement that “the
    objective evidence or the claimant’s treatment history did not
    support      the     consultative             examiner’s      findings”       precluded
    meaningful    review);       Radford,         734     F.3d   at   295;    DeLoatche       v.
    Heckler, 
    715 F.2d 148
    , 150 (4th Cir. 1983).                          Instead, the ALJ
    explained why he discredited Dr. Gibellato’s opinion, remarking
    that “the claimant’s reported limitations were not supported by
    [Dr. Gibellato’s] office notes.”                      While the ALJ did not cite
    specific pages        in   the    record,       his    explanation       relied     on   and
    identified a particular category of evidence.                        See generally 
    20 C.F.R. § 404.1527
    (c)(2); SSR 96-2p.
    Indeed, the record contains substantial evidence supporting
    the ALJ’s conclusion that Dr. Gibellato’s opinion did not merit
    controlling        weight.        Dr.    Gibellato’s         notes    indicated          that
    although     Sharp’s       symptoms       were        aggravated     by     stress       and
    activity,    medications         and    injections       regularly       provided    Sharp
    relief.       And,     according         to     Dr.     Gibellato’s       notes,     Sharp
    tolerated     injections          well        and     did    not     experience          any
    14
    complications as a result of these procedures.                           Furthermore, his
    notes   indicated        that    Sharp     often     reported          feeling    relief      of
    between seventy percent and eighty percent as a result of the
    treatments she received.                These notes, considered as a whole,
    suggested       that    Sharp     could    manage         her    pain    and     maintain      a
    routine        work     schedule,       and        were     inconsistent             with     Dr.
    Gibellato’s contrary opinion.
    The       ALJ     also     was     entitled      to        consider        whether      Dr.
    Gibellato’s          opinion     was     inconsistent           with     other        material
    evidence, such as (1) Dr. Wartella’s opinion that Sharp tended
    to “catastrophize” her pain, (2) the opinion of one physical
    therapist that Sharp had good potential for rehabilitation with
    use of a home exercise program, heat, and ice, and (3) the
    opinion    of    another        physical      therapist         that    Sharp’s       problems
    could     be    alleviated       in    part    by     a    walking       program,       or    by
    stretching and conditioning.                  See 
    20 C.F.R. § 404.1527
    (c)(2).
    Based on this other evidence, the ALJ was not obligated to adopt
    Dr. Gibellato’s opinion about Sharp’s ability to work.                                 See 
    id.
    § 404.1527(d)(1).             Moreover, we may not reweigh this evidence,
    and we must defer to the ALJ’s determination when, as here,
    conflicting       evidence      might     lead     reasonable          minds    to    disagree
    whether    Sharp       was    disabled.        See    Hancock,         667     F.3d    at    472;
    Johnson, 
    434 F.3d at 653
    .

    2.
    We    next     address         the    ALJ’s    determination          that      Sharp’s
    testimony lacked sufficient credibility.                      Sharp again relies on
    our decision in Mascio, asserting that the ALJ erred when he
    concluded        that         Sharp’s       descriptions       of        the     intensity,
    persistence,       and    limiting         effects    of    her     symptoms       were   not
    credible,    because          they   were     inconsistent        with    the    ALJ’s    own
    residual capacity determination.                   However, Sharp recognizes that
    the ALJ provided three additional reasons for his credibility
    determination, including that: (1) Sharp’s subjective complaints
    were “not fully supported by the objective medical evidence;”
    (2)   Sharp’s       treatment         was     “conservative;”         and       (3) Sharp’s
    admitted activities of daily living diminished her credibility
    regarding the frequency, severity, and limiting effects of her
    symptoms.          Sharp        nevertheless         maintains       that       the      three
    conclusions above are not supported by substantial evidence.
    We agree with Sharp that the ALJ applied the same incorrect
    legal standard that we identified in Mascio, by using the ALJ’s
    own   assessment         of     Sharp’s     residual       capacity       to    assess    her
    credibility.        See Mascio, 780 F.3d at 639.                         As we explained
    above,     the     regulations          require     that    the     ALJ     consider      the
    claimant’s credibility before determining her residual capacity,
    instead of permitting the ALJ’s residual capacity determination
    to serve as a basis for rejecting a claimant’s credibility.                               Id.
    16
    Nevertheless, we again conclude that this error was harmless,
    because      the    ALJ    provided    sufficient     additional       reasons     for
    concluding     that       Sharp’s   statements      about    the   extent     of   her
    limitations were not credible.            See id.
    In determining the extent to which a claimant’s symptoms
    affect her capacity to perform basic work activities, the ALJ
    considers, among other factors, the claimant’s daily activities.
    
    20 C.F.R. § 404.1529
    (c)(3)-(4); see Johnson, 
    434 F.3d at 658
    .
    The   ALJ    also    considers      the   claimant’s    statements       about     the
    intensity, persistence, and limiting effects of her symptoms,
    and whether the functional limitations from those symptoms “can
    reasonably be accepted as consistent with the objective medical
    evidence *    and    other    evidence.”       
    20 C.F.R. § 404.1529
    (c)(4).
    While we may not make our own credibility determinations, we may
    review       whether       substantial     evidence         supports     an      ALJ’s
    credibility determination.            See Johnson, 
    434 F.3d at 658
    .
    Here, the ALJ concluded that Sharp’s statements about the
    extent of her limitations were not fully supported by objective
    *Objective medical evidence includes “medical signs and
    laboratory findings.”   
    20 C.F.R. § 404.1529
    (a).     Medical signs
    are “anatomical, physiological, or psychological abnormalities
    which can be observed, apart from [the claimant’s] statements.”
    
    Id.
     § 404.1528(b).       Laboratory   findings  are   “anatomical,
    physiological, or psychological phenomena which can be shown by
    the   use   of   medically    acceptable   laboratory   diagnostic
    techniques.” Id. § 404.1528(c).
    17
    medical evidence.           Dr. Gibellato’s notes indicated that Sharp’s
    symptoms     were     alleviated        significantly      with       medications        and
    injections, and that Sharp tolerated the injections well and did
    not experience any complications.                 When we consider these notes
    together with (1) Dr. Wartella’s opinion that Sharp tended to
    “catastrophize” the effects of her symptoms, and (2) the above-
    stated     opinions        and     recommendations        of   the         two    physical
    therapists     who    evaluated         Sharp,   we   conclude     that      substantial
    evidence supports the ALJ’s conclusion that objective medical
    evidence undermined Sharp’s statements regarding the extent of
    her limitations.           See Hancock, 667 F.3d at 472.
    The ALJ further observed that Sharp’s medical care, which
    included injections, pain medication, and physical therapy, was
    “conservative.”              The     ALJ    was       permitted       to     make        this
    determination that Sharp’s treatment was conservative, and that
    her course of treatment supported a conclusion that she was able
    to maintain a routine work schedule.                     See Wall v. Astrue, 
    561 F.3d 1048
    ,    1058-60,         1069    (10th    Cir.   2009)    (concluding            that
    claimant’s treatment for pain, which included local anesthetic
    patches,    Motrin,        and     cortisone     injections      in    her       back,   was
    conservative).
    Finally,      the    ALJ    concluded      that   Sharp’s       reported      daily
    activities were inconsistent with her alleged limitations.                               The
    ALJ recognized that Sharp’s pain was unpredictable and caused
    18
    her   difficulties.            However,     the    ALJ      also    considered   Sharp’s
    statements       that    on    good     days,    Sharp      could   perform    household
    chores    and     shop    for       groceries.         We    may    not   reweigh   this
    evidence, make credibility determinations, or supplant the ALJ’s
    judgment with our own.              Johnson, 
    434 F.3d at 654
    .                Accordingly,
    viewing    the    record       as   a   whole,    we   conclude       that   substantial
    evidence    supports          the   ALJ’s   credibility        determination.        See
    Hancock, 667 F.3d at 472; Meyer, 
    662 F.3d at 704
    .
    IV.
    For these reasons, we affirm the district court’s judgment.
