U.S. COURT OF APPEALS2 the Commissioner of the Social Security Administration if it is not based on legal error and it is supported by substantial evidence, Reddick v. Chater , 157 F.3d 715, 720 (9th Cir. 1998). 1. Helmke failed to raise his arguments against Dr. Cousino’s May 1987 residual functional capacity assessment, and the vocational expert’s testimony based on that opinion, in the district court. Therefore, those arguments are waived. Greger v. Barnhart , 464 F.3d 968, 973 (9th Cir. 2006); Warre v. Comm’r of Soc. Sec. Admin. , 439 F.3d 1001, 1007 (9th Cir. 2006). 2. The administrative law judge ("ALJ") properly evaluated the medical evidence. Dr. Pletz’ and Dr. Luisi’s stat ements that Helmke could not work are not "medical opinions" because such a decision is reserved to the Commissioner. See 20 C.F.R. § 404.1527(e)(1). Additionally, the ALJ reasonably concluded that any opinion from Helmke’s treating physicians that he could not work should be discounted because those doctors were advocating for Helmke’s long-term disability insurance. See Matney v. Sullivan , 981 F.2d 1016, 1020 (9th Cir. 1992) (holding that a doctor’s assessment was entitled to less weight when the doctor acted as an advocate in the claimant’s attempt to obtain Social Security benefits). Further, the ALJ properly discounted the opinions of Helmke’s chiropractors. Because chiropractors are not "acceptable medical sources," 20 C.F.R.3 § 404.1513(a), their opinions are entitled to less weight than a physician’s, id. § 404.1513(d). 3. The ALJ gave clear and convincing reasons, which are supported by substantial evidence, that Helmke was not entirely credible. See Thomas v. Barnhart , 278 F.3d 947, 958-59 (9th Cir. 2002). Those reasons include the observation that the medical records fail to support Helmke’s allegedly debilitating pain symptoms. See Batson v. Comm’r of Soc. Sec. Admin. , 359 F.3d 1190, 1196- 97 (9th Cir. 2004) (holding that examination reports that are inconsistent with a claimant’s complaints or that show an ability to work undermine a claimant’s credibility). In addition, the ALJ permi ssibly noted that Helmke’s daily activities, such as walking 2.5 miles a day, freque nting the gym, and swimming 5 laps at a time, demonstrated that he was more capable than he claimed. AFFIRMED.
