Tennis Trainer Ball with String Tennis Ball with Elastic Rope Training Tool for Serving, Spiking, Setting, Hitting and Solo Practice of Arm Swing Rotations, Fits Kids, Teens and Adult

I purchased this item to help with my Cuff Rotator shoulder problem. The Physio gave me some exercises to do because we are in lock down and it all had to be online. One of the Physios suggested that I use a tennis ball between myself and the wall and to roll it around the the back shoulder area. This can cause a problem when the tennis ball falls to the ground and you spend a lot of time picking the ball up. This item with the elastic means that I can keep hold of the elastic whilst doing the exercise and not to have to stop lots of time to pick the ball up.
