Want a GREAT workout?
If you've never done any of Gunnar's ball workout's then you're in for a treat. If you have any of his other workouts then this is a great compliment to your collection!! It is a well rounded all over work out - very precise and written to challenge you - and give you a total body work out! He uses weights as well as the ball so you get muscle strength along with balance training with strengthens you 'core'!! I love it and do it at least twice a week!
