You can’t expect to improve your tennis game unless you work on improving your technique. The VeloPRO Velocity Load Harness is designed to help you develop more power, velocity, spin, and shot accuracy. It connects your heels and forces you to drive through your back heel. It teaches you how to maintain the proper form before rotation.
This training harness can improve your shot velocity and spin in just a few weeks. Simply wrap the waist belt around your body, step into the foot strap, and clip the bungee cords in. The VeloPRO is available for around $106 at this time.
