How to do it
Brace your abdominals to keep your torso still throughout each forearm rotation.
- 1
Stand with your feet shoulder-width apart and arms extended in front of you at shoulder height.
- 2
Rotate your forearms so your palms face up towards the ceiling.
- 3
Rotate your forearms in the opposite direction so your palms face down towards the floor.
- 4
Continue alternating the palm-up and palm-down rotations for the desired number of repetitions.
Expert tip
Keep your movements controlled and isolate the rotation in your forearms to effectively target the muscles.
