The Kneel & Spin focuses on trunk rotation and upper body strengthening. By engaging the muscles of the core, children are able to rotate the entire body on a pivoting platform while simultaneously pedaling the hand grips forward or backwards using the upper body. This is an excellent piece of equipment for “de-conditioned” exercisers to achieve success in their exercise program. Shipped freight, fully assembled, sized and proportioned for children. 30"L x 20"W x 36"H. Weighs 95 lbs. Recommended for ages 3-8.
