Proxy data — no direct regret survey exists for this decision. Rates are derived from satisfaction scores and access-barrier data rather than questions that directly asked about regret. See caveats below.
A 2023 ClearMatch Medicare/OnePoll survey of 2,000 Americans aged 65+
found that roughly two-thirds (~67%) regret not taking their health more
seriously when younger. Exercise is the #1 ignored doctor advice in the
same survey (21%), allowing an exercise-specific derivation of roughly
52% once diet, sleep, and preventive care are factored out. A separate
MedicareFAQ survey of 560+ retirees corroborates health as a top regret
category. On the action side, no published survey directly asks regular
exercisers “do you regret exercising?” — the question barely arises
because exercise-action regret is treated as near-zero in the literature.
The best available proxy comes from Rhodes and Mistry (2016), who found
that 95% of university students anticipated they would regret missing
physical activity, leaving roughly 5% indifferent — though this
measures anticipated regret about inactivity, not retrospective regret
about having exercised. Morrison and Roese’s nationally representative
life-regrets study confirms the pattern: within the health domain, inaction
regrets overwhelmingly dominate action regrets.
The pattern maps cleanly onto Gilovich and Medvec’s temporal model: in the
short term, the hassle of getting to the gym dominates; in the long term,
the failure to have maintained a habit dominates. Retirees do not lie awake
wishing they had skipped fewer workouts. They lie awake wishing they had
shown up.
The main limitation is measurement asymmetry. The action-side 5% is an
anticipated-regret proxy from a small convenience sample (n=120 Canadian
undergraduates), while the inaction-side rate comes from retrospective
surveys of US retirees. These populations differ in age, country, and
framing. The ~52% inaction figure is a constructed proxy — derived by
isolating exercise from the bundled 67% health-regret headline — and
should be treated as an estimate rather than a directly surveyed rate.
Still, the directional finding — that sedentary regret dwarfs exercise
regret — is consistent across every survey in the literature and is
unlikely to reverse under any reasonable reweighting.

[1]Frontiers in Psychology — Understanding the Reasons behind Anticipated Regret for Missing Regular Physical Activity
Peer-reviewed
95% of participants anticipated regret for missing regular physical activity; only 5% did not
Excerpt
“"95% of participants expressed that they would regret not being active and gave a total of 357 reasons. The dominant theme (69%) was a missed opportunity to obtain the benefits of PA, followed by shame/guilt for not being able to follow-through with one's goals or self-categorized role (28%)."

Rhodes & Mistry (2016) primed 120 Canadian university students on the public health definition of physical activity and measured ANTICIPATED regret for missing exercise. 95% anticipated regretting inactivity. We invert this: 5% expressed indifference toward missing exercise. IMPORTANT: this is anticipated regret about NOT exercising, not retrospective regret about HAVING exercised. It is an anticipated-regret proxy from a small convenience sample (n=120, undergraduates). No published survey directly measures the share of regular exercisers who regret exercising; the literature uniformly treats exercise-action regret as near-zero, but without a direct measurement.

Health regrets rank among the top domains of life regret; regrets of inaction outnumber regrets of action across domains
Excerpt
“"Health, along with education and career, emerged as one of the top domains of life regret. Across all domains, inaction regrets were more common than action regrets, consistent with Gilovich and Medvec's temporal pattern."

Morrison & Roese (2011) population-representative survey of American adults on life regrets. Health was a top-6 regret domain. Crucially, within health, inaction regrets (not exercising, not eating well) dominated over action regrets. This is consistent with near-zero exercise action-regret, though the study does not report a specific percentage for exercise-action regret.

[1]ClearMatch Medicare / OnePoll — Majority of seniors regret not prioritizing their health when they were younger
Primary study
Approximately two-thirds of Americans aged 65+ regret not taking health more seriously when younger; 81% admit their health could be better; exercising frequently is the #1 ignored doctor advice (21%)
Excerpt
“"81% of seniors polled admit their health could be better, despite the average respondent exercising about five times per week. Approximately two-thirds of Americans aged 65 and older express regret for not having taken their health more seriously during their younger years."

ClearMatch Medicare commissioned OnePoll to survey 2,000 Americans aged 65+ (August–September 2023). The survey reported "approximately two-thirds" (~67%) regret not taking health seriously. Exercise is the #1 ignored doctor advice at 21%, followed by nutrition at 16%. We derive an exercise- specific estimate: 67% × (21/(21+16+other)) ≈ 52%. This removes diet, sleep, and preventive care from the bundled health regret figure. The 52% is a constructed proxy, not a directly reported figure, but is more exercise-specific than the raw 67%.

1 in 4 retired Americans have regrets; health listed as a top regret category

MedicareFAQ survey of 560+ retired Americans. Health is a top regret category. The 25% overall-regret rate is lower than the ClearMatch figure because the MedicareFAQ question asked about regrets broadly rather than health-specific regret. Used as corroborating evidence that health/exercise is a top regret domain among retirees.
Caveats
The action-side 5% is a doubly indirect proxy: Rhodes & Mistry measured anticipated regret for MISSING exercise (not retrospective regret about having exercised), then we inverted it (those who did not anticipate regret). This is an anticipated-regret proxy from a small convenience sample (n=120 Canadian undergraduates), not a nationally representative survey measuring actual retrospective regret. No published study directly asks regular exercisers whether they regret exercising; the literature uniformly treats exercise-action regret as near-zero but without a direct measurement. The Morrison & Roese life-regrets study confirms that inaction regrets dominate over action regrets in the health domain, which is consistent with but does not directly establish the 5%. The inaction- side ~52% is derived from the ClearMatch Medicare/OnePoll survey's ~67% broad health regret, adjusted downward to isolate exercise (the #1 ignored doctor advice at 21%) from bundled diet, sleep, and preventive care regret. The 52% is more exercise-specific than the raw 67% but remains a constructed proxy. Sample populations differ substantially (Canadian undergraduates vs US retirees), so the delta should be read as directionally strong rather than precisely calibrated. Survey data are drawn predominantly from United States samples; satisfaction and regret rates in countries with different institutional structures — consumer norms, gym membership culture, and public exercise infrastructure — may differ substantially.
