1. Bicycle Crunch Exercises
Bicycle crunches are also a great way to work on your abdominal without putting a lot of strain on your back. Keeping your legs engaged during the exercise will help you burn more calories and help develop the muscles along your sides for improved balance. Lie on your back with your knees bent at 90 degrees. Place your hands behind your head and curl your shoulders off the floor. Twist your right elbow to touch your left knee while straightening your right leg. Then twist your left elbow to your right knee, straightening your left leg. Go at a slow pace and repeat 10 more reps.
