Consistency over intensity

Treat regularity as the active ingredient, not how hard any single session is.

Why it works

The neurobiological adaptations behind exercise’s mental-health effects — BDNF, stress-axis recalibration, improved sleep — accumulate from repeated exposure over weeks. A punishing session you can’t repeat delivers far less than a moderate one you do four times a week, because the benefit is dose-over-time, not peak effort.

How to do it

1. Choose a weekly frequency you’re confident you can hit even on a bad week.
2. Define a "minimum viable session" you’ll do when motivation is low, so the chain never fully breaks.
3. Review consistency, not personal records, as your primary metric for mental-health gains.

Evidence

Across the exercise-and-mood literature, regular ongoing activity predicts mental-health benefit, and benefits attenuate when activity stops — underscoring that maintenance, not one-off intensity, carries the effect. (observational)

Exact frequency and intensity thresholds remain debated; what is clear is that sustained regular activity outperforms sporadic intense bouts for mood.

Common mistake

Judging a week by whether you hit a hard PR session, then quitting after a couple of intense weeks. The mental-health payoff lives in the unglamorous, repeatable middle gear.
