driveway work– practice your swings– I use a weighted racquet and do 20 reps on each swing– with a medicine ball i work on rotation and stroke swings– i ride the stationary bike– I am reading a book as I do this so it is not so boring — i do tennis footwork drills–I do this every morning anyways– now i am doing 4 x a day- I have music going the whole time – stay well
non hitting hand
keep the non hitting hand on the racquet during the rotation
