Want a flat stomach? This exercise will target your upper abdominals.
Lift your hips upwards by contracting your upper abs. While keeping your knees slightly bent, raise your body up to a V, pause, then slowly lower your body back to the starting position.
Aim for 3 sets of 15 reps.
NEXT: Have you tried the 90-degree crunch?
