The researchers end up with a list of 13 of the best and most exercises for your abs.
Here they are. Check them out. Pick one or two to add to your routine.
1. Bicycle Crunch
Lie on the floor, with your lower back pressed into the ground. Place your fingertips lightly to your temples. Bring your knees over your hips, bending your knees at 90° so that your shins are parallel to the floor.
Slowly rotate your left shoulder towards your right knee whilst extending the left leg out away from the body. The lower down you bring the leg the more difficult this move will be.
Tips: To modify this exercise keep the knees over the hips omitting the leg extension or tap the toe down to the floor.
2. Captain’s Chair
Stabilize your upper body by gripping the hand holds and gently press your lower back against the back pad.Begin by you holding your body up with legs dangling below.
Using slow controlled movement, lift your knees in toward your chest then return to the starting position.
3. Stability Ball Crunch
Sit on the ball with your feet flat on the floor toes pointing forward. Slowly, let the ball roll back until you are now lying back on the ball with your thighs and torso parallel with the floor.
Squeeze your glutes. Place your fingertips lightly to your temples, slightly tucking your chin in toward your chest (this is the one time you want a double chin!).
Contract your abs and exhale while raise your torso up no more than 45°, inhale down to the starting position.
Tips: To modify this exercise move the feed wider apart, to make it more challenging move the feet closer together.
