SUMMARY ORDER

Chauncey Carvey appeals from the district court’s affirmance of a decision of the Commissioner of Social Security (“Commissioner”) denying his application for Social Security disability insurance benefits. In such a case, “we review the administrative record de novo to determine whether there is substantial evidence supporting the Commissioner’s decision and whether the Commissioner applied the correct legal standard.” Zabala v. Astrue, 595 F.3d 402, 408 (2d Cir. 2010) (internal quotation marks omitted). “Substantial evidence means more than a mere scintilla. It means such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” Moran v. Astrue, 569 F.3d 108, 112 (2d Cir. 2009) (internal quotation marks omitted). We assume familiarity with the facts and the record of prior proceedings, which we reference only as necessary to explain our decision.

1. Treating Physician Rule

Carvey contends that the administrative law judge (“ALJ”) erred in failing to give controlling weight to the disability opinions of two treating physicians, Drs. Padma Ram and Michael Gabris. A treating physician’s opinion is entitled to controlling weight with respect to the nature and severity of a claimed impairment if it is “well-supported by medically acceptable clinical and laboratory diagnostic techniques and is not inconsistent with the other substantial evidence in [the] record.” 20 C.F.R. § 404.1527(d)(2); see also Hallo- *52 ran v. Barnhart, 362 F.3d 28, 32 (2d Cir. 2004). That is not this ease.

Carvey’s disability claim is based on the residual effects of a relatively mild May 2003 stroke, together with poorly controlled Type II diabetes, pulmonary edema, cardiac abnormality, obesity, sleep apnea, disc protrusion, carpal tunnel syndrome, chronic radiculopathy, pericarditis, and anxiety disorder. In March 2004, Dr. Ram opined that Carvey was unable to perform any activity that could raise his heart rate, noting that her opinion was “per Dr. Simmons,” ie., Gerald Simmons, Carvey’s treating physician from February through November 2003, and “per ... cardiologist,” presumably Dr. Gabris. 1

In a letter dated October 14, 2004, Dr. Gabris stated that Carvey could perform sedentary work provided no lifting was involved. In November 2004, Dr. Gabris stated that Carvey could stand or walk for less than two hours in a typical workday and sit for only four hours a day. A review of Carvey’s treating physician challenge properly focuses on these noted limitations because, in the Social Security context, a person must be able to lift ten pounds occasionally, sit for a total of six hours, and stand or walk for a total of two hours in an eight-hour workday to be capable of “sedentary work.” See Rosa v. Callahan, 168 F.3d 72, 78 n. 3 (2d Cir. 1999); 20 C.F.R. § 404.1567(a).

As the district court correctly observed, Dr. Gabris’s own statements do not consistently conclude that Carvey cannot engage in any lifting at all. At various times, Dr. Gabris indicated that what Car-vey could not engage in was “heavy lifting,” specifically, lifting “more than five to ten pounds.” While an ALJ may not reject a treating physician’s disability opinion based “solely” on internal conflicts in that physician’s clinical findings, Balsamo v. Chater, 142 F.3d 75, 80 (2d Cir. 1998), here the record contains other medical opinions also at odds with a conclusion that Carvey was precluded from any lifting. Dr. Simmons, Carvey’s primary care physician, authorized Carvey’s return to work in June 2003 subject only to a thirty-pound lifting restriction. Meanwhile, consulting physician Kalyani Ganesh stated in March 2004 that Carvey was precluded from “heavy lifting,” while consulting neurologist Patrick Hughes concluded in February 2005 that Carvey should not lift “more than five to ten pounds.” Moreover, in his hearing testimony, Carvey acknowledged that he could carry five to ten pounds. This record provides a sufficient basis for the ALJ’s decision not to give controlling weight to a treating physician opinion that Carvey could do no lifting.

As for limits on Carvey’s ability to sit, stand, or walk noted by Dr. Gabris in November 2004, the opinion is at odds with the view expressed in Dr. Gabris’s February 2005 office notes that Carvey’s “activity [wa]s unlimited with the exception to heavy lifting.” It is further contradicted by Dr. Simmons, who, on authorizing Carvey’s return to work, noted no sitting, standing, or walking limitations, only a lifting limitation. Indeed, in May 2003, *53 Dr. Simmons encouraged Carvey to "go on about his life as he did before with the exception of straining and heavy lifting." Similarly, Dr. Ganesh, at the same time that he found that Carvey should "avoid heavy lifting, carrying, pushing, pulling," noted "[n]o gross physical limitation to sitting, standing, walking." Although Dr. Hughes indicated that Carvey could not sit for "more than thirty minutes," or stand for "more than thirty to sixty minutes," as Carvey himself acknowledged in his pre-hearing memorandum to the AU, this opinion is reasonably understood to reference Carvey's ability to sit or stand "at one time," not over the course of an eight-hour workday. Pl.'s Pre-Hr'g Mem. at 3. Thus, the record was sufficient to support the AU's decision not to give controlling weight to Dr. Gabris's opinion as to the limited total time Carvey could sit, stand, and walk during a workday.

Further, because the record evidence was adequate to permit the AU to make a disability determination, we identify no merit in Carvey's claim that the AU was obligated sna sponte to recontact the treating physicians, see Perez v. Chater, 77 F.3d 41, 47-48 (2d Cir. 1996); 20 C.F.R. § 404.1512(e), assuming arguendo that such a claim is even preserved for our review, but see Poupore v. Astrue, 566 F.3d 303, 306 (2d Cir. 2009) (holding that claimant represented by counsel in district court must present argument in that forum to preserve it for appellate review).

2. Residual Functional Capacity

Carvey's contention that the AU erred in finding that plaintiff possessed the residual functional capacity to perform sedentary work warrants little discussion in light of our conclusion that the AU was not compelled to give controlling weight to the contrary opinions of Dr. Ram and Dr. Gabris and our identification of substantial record evidence supporting the challenged finding. In light of the medical evidence supporting the AU's findings, we reject Carvey's suggestion that the AU imper-missibly "set his own expertise against that of a physician." Balsamo v. Chater, 142 F.3d at 81 (internal quotation marks omitted).

3. Credibilit'y Assess'rnent

Carvey submits that, in finding his testimony "not entirely credible," the AU failed to give proper weight to his strong work history. In reviewing this challenge, we are mindful that it is the function of the Commissioner, not reviewing courts, to appraise witness credibility. See Aponte v. Sec'y Dep't of HHS, 728 F.2d 588, 591 (2d Cir. 1984).

To be sure, "a good work history may be deemed probative of credibility." Schaal v. Apfel, 134 F.3d 496, 502 (2d Cir. 1998); see also Rivera v. Schweiker, 717 F.2d 719, 725 (2d Cir. 1983) (noting that "[a] claimant with a good work record is entitled to substantial credibility when claiming an inability to work because of a disability"). Work history, however, is "just one of many factors" appropriately considered in assessing credibility. Schaal v. Apfel 134 F.3d at 502.

In rejecting Carvey's testimony as to the severity of his impairment, the AU reasonably relied on contrary record evidence, including extensive objective medical test results, the aforementioned medical opinions, and Carvey's own account of his participation in a range of activities such as shopping, cooking, childeare, and operating a riding lawnimower, as well as attending school functions, cookouts, and auto races. See 20 C.F.R. § 404.1529(c)(3)(i). Further, the AUJ did not ignore Carvey's work history. Rather, he reasonably viewed Carvey's ability to engage in "heavy work activity" notwith *54 standing his bad back, obesity, sleep apnea, diabetes, and carpal tunnel syndrome as some evidence that his claimed inability to perform any work at all was based primarily on the residual effects of the May 2003 stroke.

On this record, we identify no error in the ALJ’s credibility assessment.

4. Vocational Expert

Finally, Carvey contends that the ALJ erred in relying on the testimony of a vocational expert because the expert’s opinion was based on a flawed assessment of Carvey’s residual functional capacity. Because we have already concluded that substantial record evidence supports that assessment, we necessarily reject Carvey’s vocational expert challenge. See Butts v. Barnhart, 388 F.3d 377, 384 (2d Cir. 2004) (noting that Commissioner may rely on testimony of vocational expert); Dumas v. Schweiker, 712 F.2d 1545, 1553-54 (2d Cir. 1983) (holding that vocational expert’s testimony satisfied Commissioner’s evidentiary burden where based on substantial record evidence).

We have considered Carvey’s other arguments on appeal, and we conclude that they are without merit. Accordingly, the judgment of the district court is AFFIRMED.
