Hi everyone, My son has been playing tennis for 2-3 years. He has developed good technique for ground strokes but are having difficulties in volleying and serving. The problem is mainly his physical strength. The racquet he uses seems heavy for him (Babolat PD Junior, 9.8oz/98 sq in /6 point HL). For instance, he needs to use two hands for backhand volley. He is relatively small for his age (75lb). But he is quite motivated to improve. Question: Is it a good idea for a 11-year old to undertake a weight training program. I'm thinking of having him do "Arme wrist roller" exercise to strengthen his forearms and lunges to strengthen his legs. And may be some push-up and crunch..etc. Any input or reference would be much appreciated.
