The Roto-Bar allows you to use heavier weights and create stronger contractions as you are able to pronate your hand at the end.
How to do:
1. Stand in a comfortable position in front of a roto-bar with your knees slightly bent.
2. Hold the roto-bar with a narrow, thumbless grip.
3. Pull the weight until your elbows are tight against the rib cage and the forearms are on a level plane extending out from the body.
4. Keeping your elbows and upper body motionless, press the bar down in a slight arc until the elbows are comfortably locked and the triceps are contracted.
5. Slowly resist the weight as it is returned to the starting position. Be careful not to cheat by swinging the weight or adding upper body sway.
