Bosu Ball Crunch
Step 1
Start seated on the edge of a bosu, flat side down, with both feet firmly planted on the floor. Carefully lie back onto the bosu, ensuring that it is following the natural curvature of your mid-back. Place your hands behind your earlobes and engage your abdominal muscles by drawing your belly button in towards your spine. This is your starting position.
Step 2
Inhale. Exhale. Tuck your chin into your chest and, using your abdominals, elevate your head and shoulder blades off the bosu, stopping when your upper body forms one straight line from your chin to your hips. You do not need to sit all the way up.
Step 3
Inhale. Slowly lower your torso to return to the starting position. Repeat for the specified number of repetitions.
