Execution:
1
Grab a single handle on each high pulley with palms facing up (supinated).
2
Keep your elbows down and close to your torso.
3
Extend both arms straight down at the same time, letting the hands drift slightly apart at the bottom.
4
Return under control by bending only at the elbows.
Tip: the supinated grip emphasizes the medial head of the triceps — use a lighter load than in the pronated version.
