Why do I always quit the gym after two weeks, and how do I break the cycle?

Because the standard way people start is almost perfectly designed to produce a two-week lifespan — and the fix is to redesign the start, not to blame your character. Look at the anatomy of the classic failed launch. You begin at peak enthusiasm and size everything to that peak: six sessions a week, an hour each, a strict diet on top, before dawn. For a fortnight, novelty and resolve cover the costs. Then three predictable forces converge. The novelty fades, so sessions stop feeling exciting and start costing willpower. Accumulated fatigue arrives, because you jumped from zero to six sessions with no adaptation base.

And visible results have not shown up yet — meaningful strength and physique change need four to eight weeks — so the effort-to-reward account is deep in the red at exactly the moment your enthusiasm account empties. Week three collapses, guilt sets in, and guilt makes returning harder — the self-determination research is clear that pressure-and-shame motivation predicts dropout, not persistence. Breaking the cycle means inverting the design. Size the plan for your worst week, not your best day: three sessions of thirty to forty minutes is the right opening volume for almost everyone, because a plan you can keep during a bad week is a plan that survives.

Make the decisions once, in advance: fixed days and times in the calendar, a written programme, kit packed the night before, and if-then fallbacks for your known derailers — the if-then evidence shows follow-through jumping from about a third to over ninety percent when the plan is specific. Make progress countable before it is visible: log sessions on a wall tracker, track your lifts, and judge the month on adherence — 75% of scheduled sessions completed is genuinely winning. Expect the week-three dip and pre-plan for it: when the flat patch arrives, run your floor sessions (ten minutes counts in full) and invoke the never-twice rule after any miss.

And drop the moral framing entirely: a missed session is a data point about a rule that needs adjusting, not a verdict on you. Start smaller than your enthusiasm wants, decide more than your mood likes, and this attempt will be the one that outlives its fortnight.
