With elbows planted by your sides, push the band down and fully extend your arms. Pause and flex your triceps briefly at the bottom before returning to starting position.
Tips:
Resist the urge to put any body weight into the pushdown.
Position your feet in a staggered stance or side-byside.
Lower yourself to raise the resistance.
Variations:
Wrap band over the top of an open door positioned perpendicular to your body.
Experiment with different grip options: underhand grip will engage forearms.
