Lie face up on the floor with your heels on a smooth surface and place a towel under your feet. Bend your knees and lift your hips into a bridge position. Keeping your hips elevated, slide your heels away from your body by extending your legs, then reverse the movement by pulling your heels back toward your glutes, contracting the hamstrings. Maintain a lifted hip position throughout for core engagement and posterior chain activation.
Log your reverse sliding leg curl on floor with towel sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
