Jack Jump
From a squat, jump and lift both straight legs up and apart in front, reaching the hands toward the shins; a gymnast's straddle jump.
How to do it
Setup
Feet hip-width, squatting down with the hands low in front.
Steps
- Jump straight up hard from the squat.
- At the top, lift both straight legs apart and reach the hands toward them.
- Bring the legs back down under the hips and land soft in the squat.
Common mistakes
Lifting the legs before the jump peaks: height first, then the straddle. Landing with the legs still apart: bring them under the hips first. Folding the chest down to the feet: lift the legs to the hands instead.
Breathing
Exhale on the jump, inhale landing.
