Good on ya for practicing your footwork. That will pay HUGE dividends as you continue to learn the game. What 95% of rec players ignore is that tennis is a
moving game as much as it is a
hitting game. They tend to get all caught up in the strokes and ignore the balance and footwork necessary to set up the stroke.
Take it easy on the physio and return to the game slowly. You've got your whole life ahead of you to play tennis!
