10 Fat Burning Ab Exercises

4. Boat Pose

This challenging yoga pose engages all the muscles in your lower body as it tests your balance, stamina, and strength. The boat pose strengthens the abdominal and the deep hip flexor muscles. Sit on the mat with your feet on the floor, legs bent. Engage your core and, keeping your back straight, raise your legs until your calves are parallel with the floor. If this is a comfortable position for you, begin to straighten your legs and stretch out your arms in front of you. Hold for 5-15 breaths, and repeat five times.
