Execution:
1
Stand and hold a straight bar overhead with a close grip, arms fully extended.
2
Keep your elbows pointing up and close to your head, without flaring out.
3
Bend your elbows to lower the bar behind your head until you feel a triceps stretch.
4
Extend your arms back to the start, squeezing at the top.
Tip: a close grip increases triceps activation — keep the bar steady.
