Range of motion

Range of motion is how far a joint moves through a lift, from full stretch to full contraction.

Full range of motion builds more muscle than partial reps for the same load. Half-reps are usually ego, not strategy.

Also known as

ROM, full range of motion

Form

Eccentric
The eccentric phase is the lengthening part of a lift — when the muscle resists while being stretched.
Concentric
