At a tennis club, I recently joined, they have hitting lanes. Briefly, there are 3 lanes on the court, so each lane is about a 1/3 of the court separated by nets. There is a ball machine. How effective would these be? Are there any suggested routines for it? My 2 handed backhand blows, so I was thinking I might try to learn how to hit a lefty forehand???? Also is this better or worse than using a wall? I recently purchased the AP Belt as well. Not sure if hitting lane will help with that. And what kind of drills would you recommend.
