Bodybuilding (tricep).

Execution

Lower under control to a full stretch behind or at the forehead, elbows pointed up and held in. Four sets of 10–12. Don't lock out and rest at the top — keep tension on the triceps the whole set.

The cue that matters

Controlled eccentric, full stretch at the bottom, no lock-and-rest at the top.

Common mistake

Turning it into a close-grip press by letting the elbows drift back; keep the upper arm fixed so the triceps, not the shoulders, do the work.
