Range of Motion (ROM)

"How far a joint travels through a rep — full ROM trains the muscle hardest."

Definition

The full breakdown. What it is, why it matters, how to use it.

ROM is the distance a joint moves during a rep. Full ROM — squatting below parallel, fully locking out a press, fully stretching the muscle at the bottom of a curl — produces more hypertrophy than partial reps at the same load. The deepest stretched position is where most growth signaling occurs.

Question 01

Are partial reps useless?

Not entirely — overload partials at the strongest range can add stimulus after full-ROM failure. But default to full ROM until then.
