Reverse Crunch W Kettle Bell

From a seated position balanced on your butt, take you kettlebell, medicine ball or dumbbell and extend it away from the body as your legs go straight and lower towards the mat. The lower you go the harder this is, so work withing your ability. Doing this super slow will place a huge demand on your core and lower back.

Focus on keeping a tight core, especially towards the bottom of the movement where you will exhale.
