Tennis Swivel Disks. Tennis Trainer. Swivel Disks Topspin groundstrokes become powerful weapons when the entire body is used to generate force. Our Swivel Disks help players feel optimal body rotation needed to generate powerful topspin forehand and backhand groundstrokes. Each 11" slip resistant Swivel Disk has dozens of steel ball bearings to ensure a smooth circular glide. Some coaches call the movement experienced with Swivel Disks the "figure eight" rotation. Whatever you call it, players will gain a quick feel for naturally opening the hips to gain more power from the body's core. A second benefit is increased loading of ground forces, the result of improved balance. The force comes from two primary source directions: Force #1: Linear force comes from the ground and is initiated by flexing the knees and loading force downwards to the ground. Players on Swivel Disks automatically bend their knees for balance, loading even more energy to the ground than normal. Swivel Disks help players increase their linear loading sensation. Force #2: Angular or Rotational force comes from the rotation of the body core, including the hips and shoulders. The hitting arm and racquet are extensions of this core rotation. Swivel Disks help players more freely experience this rotational force and translate this rotational force into real play. Some coaches call the movement experienced with Swivel Disks the “figure eight” rotation. Whatever you call it, you will find that it helps players gain a quick feel for naturally opening the hips to gain more power from the body’s center or core. Swivel Disk Progressions
