A training routine that actually holds: three sessions a week

By Linus Persson 2026-08-06

Exercise is one of the best-researched interventions for living longer. But the variable that decides your result is not volume, intensity or programme design — it is whether the routine survives contact with a normal week. Here is the framework we use to build one that does.

The short version

Three sessions a week is enough. Consistency outperforms volume by a wide margin.
Strength work is not optional. Squat, hinge, push, pull — that is the whole list.
Everyday movement counts. Walking, stairs, standing up often.
Recovery is half the job. Sleep and protein, not more sessions.

Start with why

Before deciding how to train, decide what you are training for. Living longer, building muscle and managing stress are three different goals with three different-looking weeks. For longevity specifically, the combination that shows up in the evidence is strength, cardiovascular fitness and mobility — not any one of them taken to an extreme. Pick the goal first; the programme falls out of it.

Three sessions a week is enough

You do not need to train daily to get results. Three varied sessions a week captures the large majority of the health benefit that exercise offers, and the rest comes from what you do between them — walking, taking the stairs, getting up from the desk. The people who train four times a week for a decade are in far better shape than the people who train six times a week for two months, every time.

Strength training is non-negotiable

After the age of thirty, adults lose one to two per cent of muscle mass a year without resistance training. Muscle protects against falls, keeps glucose metabolism working, and behaves as an endocrine organ in its own right. You do not need a complicated programme: squat, hinge, push, pull, progressively loaded. Four movements, twice a week, done properly, will outperform any amount of variety done sporadically.

Recovery is where the adaptation happens

Training does not make you stronger. Recovering from training makes you stronger — the session is only the stimulus. Sleep, protein and stress management are not the soft edges of a programme, they are half of it. If you train hard and recover badly, you go backwards, and the usual first sign is that your performance stalls while your motivation quietly drains away.

Supplements that support the work

Two are worth the money for most people. Creatine is among the most studied supplements in existence — Creatine Monohydrate Powder is plain micronised monohydrate. If protein intake is the gap, Lineage Complete Protein or Blueprint Longevity Protein at 26 g per serving will close it, and Whole Body Collagen supplies 10 g of collagen peptides per serving for connective tissue. Browse muscles and recovery for the full range.

Summary

Three sessions a week, built around four basic strength movements, with walking in between and real recovery around it. That is a routine that still exists in five years, which is the only property that matters. The best programme is the one you are still running when it has stopped being interesting.
