What It Is
A plank with your feet hanging in straps. Your whole midsection works harder to keep your body still and straight.
How to Do It
Set the straps so the foot cradles hang at mid-calf height. Lie face down on the floor and hook your toes into the cradles. Rest your forearms on a mat or folded towel, elbows under your shoulders. Lift your hips into a straight line and hold.
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.
