Jack Press
A jumping jack holding a medicine ball: press it overhead as the feet jump wide, bring it back to the chest as they jump in.
How to do it
Setup
Feet together, a medicine ball held at the chest in both hands, elbows down.
Steps
- Jump the feet wide and press the ball straight overhead.
- Jump them back together as the ball returns to the chest.
- Keep the ribs down as the arms lock out.
Common mistakes
Arching the back under the ball: ribs down, glutes tight. Ball drifting forward overhead: finish it over the crown of the head. Feet and arms out of sync: the press and the jump land together.
Breathing
Exhale pressing, inhale returning.
