    How much force/effort is exerted by the bottom arm in the double handed backhand?

    Multiple Grips

    She came to So Cal to work with Robert when she was like 11--but that was intermittent. I have film of that because I was down there doing some articles with Robert--just coincidence that I filmed Maria. I remember Robert saying you should film this Russian kid--she's pretty good. On the...

    Big changes coming to coaching certification

    He did play on a college tennis team. I think my designation is about right based on what I saw when I was at his academy as a kid and what other coaches there have observed and said. Totally agree that his talk was his greatest weapon/asset.
