What is progressive overload?

Progressive overload means gradually asking more of your muscles over time so they keep adapting, usually by adding weight or reps. A 2022 study found adding reps worked about as well as adding weight for building muscle, so you don't have to add weight every session. The key is that some number goes up over weeks and months.

1. Pick a rep range. For example, 3 sets of 8 to 12 reps.
2. Start at the bottom. Choose a weight you can lift for 8 good reps with 2 or 3 left in reserve.
3. Add reps. Each session, try for one more rep on one or more sets.
4. Add weight. When you reach 12 reps on every set, add the smallest weight you can. Then start again at 8.

Why it works

Muscles adapt to what you ask of them. Once a weight feels easy, it has stopped being much of a challenge. The American College of Sports Medicine’s guidance for healthy adults is built on raising the challenge over time.

Ways to progress

You have more options than adding plates:

• Weight: the classic. Add the smallest jump your gym allows.
• Reps: do more reps with the same weight. Research suggests this works as well for muscle.
• Sets: add a set to an exercise, within what you can recover from.
• Quality: a fuller range of motion, a slower lowering phase or shorter rests with the same weight.

The one thing you need

A record. Progressive overload depends on knowing what you did last time. Without it, most people repeat the same weights for months without noticing.
