What It Is
A plank with your hands on hanging straps. The added wobble makes your whole midsection fight to keep you steady.
How to Do It
Lengthen the straps so the handles hang near your knees, and grip them facing away from the anchor. Walk your feet back and lean forward with straight arms until your body forms a straight line. Hold still with your hands under your shoulders.
Skill Level
Intermediate. Free-weight lifts, single-leg balance under load, or near-bodyweight strength moves. Form matters.
Type
Strength. Builds muscle and strength with controlled, resisted movement.
Engagement
Bilateral. Each rep works both sides of the body at once.
