    how do people decide between 1hbh and 2hbh?

    Great Lansdorp video. I know I filmed it and edited in the pro footage. Even if it was pirated and put on UTube...

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

    There are multiple arm configurations on the two hander and these in turn result in different uses of the two arms at different times in the swing. Bent bent is more the lefty forehand. Straight straight has more one-handed backhand front arm. Bent straight is in between. Better film...

    Multiple Grips

    I definitely can see it for slice--and there are slight grip adjustments for different volleys. But I do think it's misguided to have a significant range on the forehand for example.

    Multiple Grips

    Or just have one groundstroke grip per stroke.

    eyes on the ball at contact

    So your eyes film at about 20 frames a second. Contact is about 4milliseconds. As Vic Braden once said, no one has actually seen a human being hit a tennis ball. The question becomes what should you do over the course of the flight of the ball to make great contact?

    Big changes coming to coaching certification

    One more Lansdorp quote: " I never met a tennis parent who didn't think their kid was one lesson away from winning a Grand Slam."

    Big changes coming to coaching certification

    Chris, Yes college is a better play since you have a better chance of being attacked by a great white shark than making top 50 in the world.

    Big changes coming to coaching certification

    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.

    Nick is over 80! But was probably more like a really good 4.5 or even 5.0 in his day.

    How to Improve Serve? Willing to Pay

    Cailean, Probably I could help. Mail me some video at videotennis@metricmail.com It's only making a few key positions.

    Open stance was being taught as early as 1987

    All bad jokes aside, it's key to distinguish between semi-open and open stance.

    Game Based Approach To Teaching

    Junior tournaments can be so toxic for young players though. I saw a stat that only 1 of 7 kids that played a first tournament ever played another. Team competitions I feel are the way to introduce more intense competitive play. But games of all kinds need to be a part of kiddie instruction.

    I was there when he called you and wanted to know what Tommy Haas's backhand grip was!

    Zip, Jake, If true, he is not the only one...

    Wrist Acceleration!?

    Zip, But he is good as a corner man for Serena et al... Different coaches have different strengths to put it gently... PS who is Pepe?

    Wrist Acceleration!?

    Pilot no idea on that one... But it's shoulder arm and racket rotation as a unit, not technically pronation which is only the forearm.

    Wrist Acceleration!?

    You don't need a death grip to inhibit wrist movement. I always liked the analogy hold on tight enough to keep a small bird in your hand but not tight enough to crush it. Applies on most shots. Volleys might be a little tighter.

    Wrist Acceleration!?

    Never seen a good server open his hand the way patrick describes either... maybe he has some video I don't...

    Wrist Acceleration!?

    Pilot, Yes I did or rather Brian Gordon explained it to me. The inhibation sets the racket angle for the shot line.

    TW Coaches, Show us what you got! Post a video

    Henin, Yeah that's what I thought it would be about the serve. Crazy! Also don't like the the open racket face on the finish on the one-handed backhand model they show...or the forehand volley grip. But if they are getting kids playing it's all positive.
