Tons of fun are just a hop, skip and a jump away when the Moonhopper Jumper from Togu is added to the mix. Similar in shape to Saturn, the Moonhopper features a bouncy ball with a solid platform ring encircling the center, so that half of the ball is above the ring and half below it. The Moonhopper is ideal for improving coordination, balance and ankle stability. It's an overall workout that's part aerobic and part strength training. For first time users, it's recommended to hold onto a door, wall or another person when first stepping on the platform. When you get on the disc, place one foot to either side of the ball and grip the ball between the heels. Once balance has been established, the hopping can begin. To be used safely, the corrugated surface of the disc and the ball valve must always be facing upwards. The Moonhopper will arrive properly pre-inflated. Users can however inflate or deflate as needed. Easy to store as it's only 16" x 12" x 12" and easy to move where needed weighing just over 2 lbs. Please note, this Moonhopper has a weight capacity of 155 lbs. The Moonhopper should only be used with trainers or sneakers, NEVER with just socks and never barefoot. Safe for children, the ball strengthens the core and encourages socialization as kids initially work together finding balance and then, after more experience, having races and inventing games. As an added challenge for experienced Moonhoppers, start the hopper spinning and then jump onto it with both feet, landing and gripping each side of the ball with the heels. Easy to clean with just a damp cloth and mild soap. Please note, inflation pump not included.
