Flat Abs Fast: Core-Sculpting Resistance Workout

Crouching Tiger

Targets: Back, arms, abs, and quads

-- Stand with feet hip-width apart on center of tube, cross it once or twice in front of you, then grasp a handle in each hand, arms by sides.
-- Crouch down and walk hands forward until you are in full push-up position, arms extended with palms directly under shoulders, legs directly behind you so that you form a straight line from head to heels. (Hold handles lightly by thumbs so that palms can lie flat on floor.)
-- Keeping palms planted and abs tight throughout, press hips back toward heels, bending knees so that they hover just above floor.
-- Straighten legs to return to full push-up position and complete rep.
-- Do 16 reps.
