Get into a push-up position and place one foot on top of the other, so your whole lower body balances on a single set of toes. Keeping your body in a straight line, lower your chest toward the floor and press back up. With your base narrowed to three points, every rep doubles as an anti-wobble contest - your core has to grip hard just to keep your hips from swaying while your arms do the pressing.
Works: chest, shoulders, triceps, core
Breathing: Inhale as you lower, exhale as you press back up.
Common Mistakes: Letting the hips sway or rotate toward one side, sagging through the lower back as the set wears on, and cutting the range short to protect the balance.
Make Easier: Unstack the feet and build volume with regular Push-Ups, or keep the feet stacked and do partial reps until the balance feels solid.
Make Harder: Slow the lowering to a 3-count, or move on to Push-Ups - Dragon for the reaching version of unstable pressing.
