So I've been in tiny Slovenia for the past month, across coach Tomaz from Feel Tennis.com. I'm coming from a background of no hand/eye sports or activities and about 1-1.5 years of learning tennis. I'd roughly assess myself as a strong 3.5 to weak 4.0 player, with limited match experience. Oh yeah, I was born a lefty but converted over to a righty because that's how they did things in boarding school three decades back. What I'm saying is I have extremely poor awareness of my body, to arrive at a decent kinetic chain is misery in itself - when I was younger [Toronto] I'd shy away from throwing sports [baseball, football] and veer towards cardio type activities like running, or hockey. Even now, if you ask me to toss a baseball I can barely manage to do it in a straight line. So arriving in Ljubljana I came determined to fix my wonky forehand. From the baseline I tend to arm it, like many rec players do. My backhand [single handed] has always been smooth and needed little help except for some basics to generate perhaps some lift. But my forehand is a right mess. It's wristy/arm'ie and generally missing everything that happens before the contact point [legs/hips/shoulders etc]. Coach Tomaz is in my mind the finest coach for helping you with kinetic chains. He's had years and years of dealing with adults so focuses on biomechanics. His methodology is to isolate different parts of the body so you have a reference "feel" and then gradually stitch them all together in the correct order of the kinetic chain. If you haven't already do check out feel tennis.com and his many videos. And if you're an adult, somewhat like myself, and you're determined to learn this awfully frustrating sport, the many coaches out there that tell you to do this or that, without showing you what that feels like, will probably make it an exhaustive process. Also, Ljubljana, is a really neat little town. I tend to travel a fair amount, to me this is a better place to play tennis [weather, people, food, cost] than Spain (as an example).
