24 Fat-Burning Ab Exercises (No Crunches!)
An advanced Pilates-inspired move. Lie on your back with knees bent to 90-degree angles and feet lifted. Tighten abs as you inhale, and lift arms up and back over head.
Exhale and swing arms forward, straightening legs so your body forms a V. If needed, put hands on the floor for support.
Roll down slowly, bending knees and bringing arms overhead. Do 15 reps.
