What is the simplest way to apply progressive overload?

Write down what you lift. Next session, try to beat something — a rep, a load, a cleaner set. A log and the intent to beat it is the entire minimum viable system.

Does it apply to people who do not want to get big?

Yes. Strength, bone density, and body composition all respond to the same principle at whatever intensity matches your goal.

WHAT IT IS

The principle that muscle and strength adapt only when training demands increase over time — more load, more reps, more quality sets. Every effective program ever written is an implementation of it; most abandoned programs quietly stopped applying it.

HOW IT WORKS

Muscle fibers grow in response to mechanical tension they have not already adapted to. Hold the stimulus constant and adaptation stops — the body has no reason to keep building. Tracked, gradual increases in demand are the signal; everything else in a program exists to deliver that signal repeatably.

WHERE THE EVIDENCE STANDS

A formal position stand, global physical-activity guidelines mandating progressive resistance training, and decades of trials comparing progression schemes. The debates are about flavors of progression. Nobody credible disputes the principle.

WHAT PEOPLE GET WRONG

You have to add weight every session.: Progression includes reps, sets, range, and control — and it is measured across weeks, not days. Demanding linear increases forever is how people get hurt or quit.
Supplements can substitute for progression.: Every supplement on this index, combined, is worth less than a training log used honestly. The stimulus is the product; everything else is support.
