We have a Bo-flex we bought several plus years ago & a Bo-flex Tread Climber. We also use a floor ball. The Tread Climber we locked the treads in place. It moves like a treadmill & climbs at the same time. We do an average of 30 different exercises on the bo-flex/treadclimber/floor ball/floor 3 times a week. It doesn't take long & we feel so much better when we exercise. Oh...I also have fibromyalgia & this really helps me.
