Many athletes have the following problem - they seek to improve their sport performance while doing an overly large amount of the their training in the weight room.
Tennis players, on the other hand, have the reverse problem. They spend way too much time on-court and their off-court training closely resembles (or mimics) what they’re already doing on the court.
Then there are coaches and players (even parents) that often seek ‘tennis-specific’ training. Depending on how you define it, ‘tennis-specific’ can mean a lot of different things.
