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’s advice in the same survey (21%), ahead of nutrition (16%), scheduled appointments (13%), and medications (12%) — the single largest named lapse within that broader regret figure, though the survey does not report a regret rate isolated to exercise alone. 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. Roese and Summerville’s meta-analysis of regret-ranking studies confirms the broader temporal pattern: regrets of inaction persist longer than regrets of action, because they remain psychologically open.

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 67% comes from retrospective surveys of US retirees and measures general health regret rather than a rate isolated to exercise specifically. These populations differ in age, country, and framing, and the 67% should be read as a general-health proxy for exercise-related regret — not a directly surveyed exercise-only 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.

    Understanding the Reasons behind Anticipated Regret for Missing Regular Physical Activity
    Statistic
    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%)." ”

    Calculation
    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.

    Roese & Summerville (2005) meta-analysis of 11 regret-ranking studies of American adults. Health is NOT a top-six regret domain in this paper (education 32.2%, career 22.3%, romance 14.8%, parenting 10.2%, self 5.5%, leisure 2.5%; health ranks lower). The relevant finding for this entry is the general action/inaction asymmetry: regrets of inaction persist longer than regrets of action because they remain "psychologically open." This supports the directional inaction-dominates pattern (regretting not having exercised outlasts regretting having exercised) but does not report any exercise-specific percentage.

    Calculation
    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 -- used directly as regret_rate. Exercise is the #1 ignored doctor advice at 21%, ahead of nutrition (16%), scheduled appointments (13%), and medications (12%), confirming exercise is the single largest named lapse within the 67% figure, but the survey does not report a regret rate isolated to exercise alone. A prior version of this entry derived an "exercise-only" estimate via 67% × (21/(21+16+other)) ≈ 52%, which is mathematically impossible: with other ≥ 0, that formula's own maximum (at other=0) is 21/37 × 67% ≈ 38%, well below 52%, and the now-confirmed additional ignored-advice categories (appointments 13%, medications 12%) push the true ceiling of that approach lower still (21/62 × 67% ≈ 23%). Since no published breakdown isolates exercise-specific regret, this entry now reports the directly-surveyed 67% general health-regret figure instead of a fabricated derivative.

    This URL was previously cited here for a MedicareFAQ retirement- regrets survey (1-in-4 retirees regret retiring; health listed as a top regret category). Re-fetching the live page found different content: it is now titled "Retirement Regrets of Seniors: What You Can Learn from Their Mistakes" (byline dated 2026-04-08) and covers Medicare enrollment/coverage-gap planning mistakes -- over 60% of retirees affected -- with no health-regret or exercise-regret survey data. The prior claim that this source "corroborates health as a top regret category" does not match the page's current content and has been removed accordingly. This source is retained only as general retirement-mistake context; it does NOT corroborate and is not used in deriving the 67% regret_rate, which rests solely on the ClearMatch Medicare/OnePoll survey above.

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. Roese & Summerville's regret-ranking meta-analysis finds that regrets of inaction persist longer than regrets of action in general, which is consistent with but does not directly establish the 5%. The inaction- side 67% is the ClearMatch Medicare/OnePoll survey's directly-reported general health-regret figure, not an exercise-isolated rate -- exercise is simply the single most commonly named specific lapse within it (the #1 ignored doctor's advice at 21%, ahead of nutrition at 16%, scheduled appointments at 13%, and medications at 12%). A prior version of this entry attempted to isolate an exercise-only share via 67% × (21/(21+ 16+other)) ≈ 52%, but that derivation is mathematically impossible (its own maximum, at other=0, is roughly 38%) and no published breakdown actually isolates exercise-specific regret, so this entry now reports the direct 67% instead. 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.
