The point which I'm making is that with racquet as light as 0.7lbs why does that poster insist that you need to be strengthening using a 25lb loading force? It doesn't make sense.
I had a sports medicine doctor advise me to use the flex bar. He said it is used to stretch out the tendons. keep the muscles and tendons working and loose to bring blood to the area. Its the blood supply that helps the healing. He claims if you just rest it is actually not as helpfully as using the flex bar and other exercises. You need the blood to flow there. the tendons get very little normal blood flow.
