I have 2! i first got one, then when friends and family started trying i needed another. this is without a doubt a full body workout. it was a little difficult at first, but i kept at it and now i keep improving, carving turns, small turns, big turns, never a dull moment. it has helped my chronic m back issues and i feel confident this upcoming ski season i'll be both cardiovascularly and and balance fit ready! i'm now getting the Pro!
