Muscle Extreme XxlStability balls are universally used for core building up. Balancing your body on the ball while performing standard exercises like sit-ups, crunches, and planks focuses the stress of the movement on the core muscle groups. Be sure to have a post workout meal of protein and carbs to increase the speed of repair and recovery. You'll need at least your bodyweight in pounds x 18kcal (A unit of heat energy total 1000 calorie). You'll be eating a lot of food in order to build muscle. That is why you must be absolutely positive that you will undertake this transformation.
