I'm fortunate to play at a national tennis training center where I have access to some of the best coaches in my country. However, each coach just showed me how to play like one of their favourite ATP players. No one adapted their coaching to me. It's like teaching a student how to dance by ballroom dancing in front of him and then asking him to repeat...without music. And repeat...
Video analysis is the way to go. Tom dissected my stroke and found one fundamental flaw that no one had seen. My balls are now more consistent and penetrating. I'm more confident so I'm more relaxed. My strokes are smoother and timing easier which cycles back and helps all parts of my forehand.
Tom unlocked my forehand. His greatest strength is that he doesn't overhaul everything. He works with what you've got. Within a short time, your feel for the ball will improve and I guarantee you'll play better and have more fun. And isn't that what it's all about?
