In an ironic twist, the thing that causes tennis elbow (tennis) – can also help in the recovery process. Just hold a regular tennis ball held in your palm – and squeeze it as hard as you can. Initially, you will find this to be difficult – since your hand will have very little strength. As you do this more and more – you will find your grip getting stronger. This is the simplest and one of the more effective exercises that I did. I carried that ball everywhere (I didn’t care if other lunch folks saw me squeezing a tennis ball while waiting for my food..). Again – like the rest of the exercises – there is no limit to how often you do this. As much as possible!
