The present invention provides for a gymnastics swing trainer. The device comprises two parallel side support members and two fixed rungs forming a rectangular frame. An adjustable rung may be positioned along the side support members to accommodate the size of the user. A gymnast grasps the adjustable rung while placing her feet on the lower fixed rung. The rungs should be spaced the proper distance apart to allow the gymnast to maintain the proper hollow body position required for uneven parallel bar skills. Repeated training with the device allows for the proper body position to become an automatic response or to be retained in “muscle memory” such that the gymnast can focus on the skill while maintaining proper position.
