The ideal set for the Junior Jumper! This set might seem little, but it has a lot to offer! The PolyJump Blocks and MultiJump Wings are designed to give you a variety of heights and challenges to your exercises by simply rotating the jumps! The MultiJumps have 7 different heights when it's stood upright, but rotate it over and you get a longer jump with lower pole heights. The PolyJump Blocks are also great for beginners as they are lightweight and easy to move around.
