@wellroxwellness: Core Killer: Hollow Tucks For an even greater challenge - add ankle weights! Brace before you move, exhale as you bring your knees in, and extend your legs only as far as you can maintain control. Keep the movement slow rather than using momentum. Save this for your next BUILD session. #ankleweights #HollowTucks #CoreWorkout #BodyweightStrength #CoreControl
