Before WOLLMAN, MURPHY, and COLLOTON, Circuit Judges.
                         ___________

PER CURIAM.

       Jaeson Riggan appeals the district court’s1 order affirming the denial of
disability insurance benefits and supplemental security income. In his November
2001 applications, he alleged disability since April 1999 from chronic bronchitis and
low-back pain, asthma, chronic obstructive pulmonary disease (COPD), and
depression. After a May 2003 hearing, an administrative law judge (ALJ) determined


      1
      The Honorable Bobby E. Shepherd, United States Magistrate Judge for the
Western District of Arkansas, to whom the case was referred for final disposition by
consent of the parties pursuant to 28 U.S.C. § 636(c).
(1) Riggan’s bronchitis, with underlying asthma, and his back problem, were severe,
but not of listing-level severity, alone or combined; (2) his statements about his
impairments and their impact on his ability to work were generally credible but
supported a finding that he could perform a wide range of sedentary work; (3) his
residual functional capacity (RFC) precluded his past relevant work; and (4) based on
a vocational expert’s (VE’s) testimony, Riggan could perform other jobs existing in
substantial numbers regionally and nationally. The Appeals Council denied review,
and the district court affirmed. Having carefully reviewed the record, we conclude
that substantial evidence supports the ALJ’s decision. See Draper v. Barnhart, 425
F.3d 1127, 1130 (8th Cir. 2005) (standard of review).

       We reject Riggan’s argument about meeting a respiratory listing, because he has
not specified a respiratory listing he meets, nor has he linked the medical-record
entries he references to requirements for any of the nine respiratory listings. See
Vandenboom v. Barnhart, 421 F.3d 745, 750 (8th Cir. 2005). We also reject Riggan’s
contentions that the ALJ’s credibility findings were based solely on the lack of
corroborating medical evidence, and that the ALJ ignored more recent medical records
supportive of his claims. Because the credibility findings are supported by multiple
valid reasons, they are entitled to deference. See Goff v. Barnhart, 421 F.3d 785, 791-
92 (8th Cir. 2005).

       As to Riggan’s challenges to the RFC findings, the findings were based, as
required, on the medical records, the observations of treating physicians and others,
and Riggan’s own description of his limitations. See Stormo v. Barnhart, 377 F.3d
801, 807 (8th Cir. 2004). The RFC opinion by treating physician Bruce White, upon
which Riggan relies, could reasonably be interpreted as related to Riggan’s ability to
perform his past work; and more important, it is vague and conclusory. See Ellis v.
Barnhart, 392 F.3d 988, 994 (8th Cir. 2005) (medical-source opinion that applicant
is disabled or unable to work involves issue reserved for Commissioner and is not type
of medical opinion to which Commissioner gives controlling weight). As to Riggan’s

                                         -2-
reliance on the records of Dr. Kimberly Agee, in June 1999 (when Riggan, by his own
reports to physicians, was still smoking) she noted that he had not been to work in
over a month, and that if his condition was purely an occupational disorder, she would
have expected improvement. This is not supportive of a finding that Riggan was
disabled from all work. The nonexertional limitations the ALJ included--avoidance
of moderate exposure to pulmonary irritants (e.g., dust, fumes)--were the only ones
supported by substantial evidence. And significantly, the ALJ discounted the RFC
opinions of Social Security Administration reviewing physicians, and tailored his RFC
findings for the most part to Riggan’s testimony. Because the ALJ’s RFC findings are
supported by substantial evidence, Riggan’s vague challenge to the hypothetical
necessarily fails as well. See Goff, 421 F.3d at 794 (hypothetical question is sufficient
if it sets forth impairments supported by substantial evidence in record and accepted
as true).

      Riggan’s remaining arguments, which are undeveloped, provide no basis for
reversal. Accordingly, we affirm.
