Alternating Tabata: Mountain climbers & Jumping jacks
Supine Knees to elbows: Set a portable pull up bar 12-18 inches off the ground. Lay on your back with arms fully extended and gripping the bar. Bend knees if needed for a “hollow” spine position. Slowly, using momentum as little as possible curl hips and torso to bring knees to touch elbows. Lower legs back to the ground as slowly as possible while maintaining “hollow” spine position. Speed can be increased only if midline is stable and movement is controlled. Now try to achieve the same position suspended from the pull up bar in a traditional upright position.
