Your entire core—shoulders to hips—stabilizes your body, so it’s critical to keep it strong. Core Up reviews the musculature of the core and upper-body muscles, addresses any misconceptions you may have, and provides you with a multitude of training techniques that you can use with your students and clients right away. Core Up is perfect for personal trainers and group exercise instructors.
This is a live recorded session from the 2008 IDEA World Fitness Convention™.
