I am a former High school / Community College player who loves the game. Grew up teaching myself when I was 10yrs old. Been training my son about 1 year now. Averaging about 10 yrs a week on the court. Our main goal was to learn a sport and in the process, get in shape since he was overweight. He started at 59inches - 158lbs and now 60.5inches and 148lbs. He is not an natural athlete But then neither was I when I was 10. I never expect him to turn pro. I just want him to experience the journey. Overcome the hardship which will prepare him for obstacles in later life. We do the normal feeding drills. I have a ball machine that we use once a week or so. He goes to clinics about once a week. He hits pretty decent in drills. He has issues with footwork and it really shows when he is trying to "rally". The problem is, I have a hard time rallying with him due to my extreme topspin strokes. When I switch to an eastern grip, I often hit either nice deep balls or very short balls and it makes things even tougher for him. In clinics, he does better with rallying with kids. Well, he hits with a lot of top and the other kids usually have a hard time and maybe that's the reason he does better. I personally hate the clinics because I always feel that for the time spent, he could be hitting 3x the balls with an 1 on 1 with me. I am looking for advice (other than just keep hitting with him) where we can work on his movements / anticipation during rallys. I have some videos of him drilling but nothing from actual rallying. Thanks for the support in advance.
