    Stay on balls of feet or land on heel first?

    If you ask how is the foot first touching the court and look at high speed videos to observe it, you can do some statistics on what is being done. The above video shows a linear forehand vs a circular forehand. This linear forehand - his last foot placement before stroke for both feet is...

    Hit Easy Slice serve with more power

    From memory, I would expect that this impact location is typical. To single frame on Vimeo, stop, hold down the shift key and use the arrow keys. I would say that most impacts are in top half of the racket face and a little left of the racket face centerline. I don't think as many are in...

    Starting after a few months, trying to change a few things

    Pick a change at the beginning of a stroke, make that change before your old stroke habits come back and start a different sequence of sub-motions. This also can work without the lay off from playing tennis.

    What do you even call that shot Joker hits ??

    I see it is a great video for showing the stroke. The camera angle was carefully chosen. To single frame the Vimeo keys work - hold down the shift key and use the arrow keys. I believe that it is skipping frames - so no single frame? Playback at 0.5x speed (click gear). It looks as if...

    What do you even call that shot Joker hits ??

    We really get a good look at his arm, hand and racket in that video. It is a new stroke to me and a great video that MaxTennis found. Make the screen full and look at the wrist band mark for pronation. It looks as if the pronation motion may be related to impact, the wrist band mark moves...

    What do you even call that shot Joker hits ??

    There is a tricky and confusing usage of terms for either Joint Motion or Joint Position Position. Usage can be to specify the position of the joint in degrees from a defined "0" degrees. See videos on measuring joint angles. 'His angle of pronation is 70 d.' Motion. Usage can be to indicate...

    What do you even call that shot Joker hits ??

    Video starts on the stroke close-up at 26 sec. Great video. Djokovic has his back facing the net and opponent and upper body is bent over. The largest muscles attached to the upper arm are the pec and lat. The large lat muscle can usually shorten and get considerable power. One rotation...

    Who was the first player with an ATP forehand?

    I have been looking at the step-forward-weight-shift forehand (or linear) vs the more circular forehand by looking at the forward trunk movement and if a step forward is present. For the circular forehand, the body does not move forward. Both are high level forehands and probably in use by the...

    Who was the first player with an ATP forehand?

    Borg had a big top spin forehand. Through his junior career he was told to drop the top spin. He also hit top spin with a two hand backhand. His 2HBH stroke had something at its start that seemed unique to Borg, sort of a little vibration, Buuzit, then the forward swing. High speed film...

    Help with the one hander

    Use high speed video to observe what you are doing. One camera view for racket face angle would show the top of the frame camera viewing along the racket shaft. This camera view. I used high speed videos to observe sub-motions of one hand backhand techniques in the ATP. Some important...

    Medvedev Forehand

    Watching Medvedev at the AO, he seemed to have intense and very quick head movement to look at the ball during forehands. Here is a big forehand, that appeared awkward in some way, but was a very strong shot. His ball watching was very locked on. See 27 sec for the best clip. To single frame...

    Needed - Strong Kick Server for Video Measurements.

    Here is a thread showing the racket tilt for probable kick serves (they were not confirmed by the bounce to the right). The most information on the racket tilt for the kick serve is in thread Junior Twist Serve.

    HELP-I toss the ball too soon in my tennis serve.

    The timing of the serve - between toss release and impact - is closely related to the peak height of the toss. For timing issues first video the height of your toss. What is your glitch? Why do you say that "but what was causing it was tossing the ball too soon, like right away." When do...

    Got Questions you need answers to?....maybe I can help

    Your video on serving and throwing A comparison of the throw and serve shows that the upward throw and the serve are very similar. A practice technique that simulates the serve so closely is very rare and interesting (this is the only technique that I have found.) . Do you have any more...

    Too Much Shoulder Rotation?

    I find this Dan Brown video very informative for analyzing and displaying the difference between a weight-shift step-forward linear forehand and a more modern circular forehand. Note how similar the uppermost body turn is for both techniques. See especially "Linear Momentum" vs "Circular...

    What do you guys think about serve technique?

    They say that many ATP servers use a kick serve as their second serve. The percentage of kick serve usage is high in the ATP. For two or three years, I looked for high speed videos on the internet that clearly showed how the racket contacted the ball. Finally, I found some videos showing the...

    Too Much Shoulder Rotation?

    Red & crossed out in the above quote, I don't agree with. The timing of separation is not "leading with the upper torso". There is separation on take back and the hips often lead the forward swing. (think of stretching abdominal muscles and timing) Stop translating your first thought into new...

    Grunting and other noises made during and after a tennis stroke - Making sounds or grunts may have some advantage for the player hitting the ball, to be determined. But making sounds should be controlled in some better way than ignoring sounds because they are difficult to police or to avoid...

    My first video - some serving

    The most important part of the serve is during the 4 milliseconds of impact. Details of that require very high frame rates and more than one camera view and so are hardly ever available. The second most important part of the serve is the racket's high speed approach to the ball. Frame rates...

    Walking into the serve style

    A 2015 thread https://tt.tennis-warehouse.com/index.php?threads/knee-pain-with-platform-stance-serve.538865/ What I get out of this for the serve is to take high speed videos that include the feet and legs both jumping and landing (left foot/knee for right hander). 60 fps videos may be useful...

    Walking into the serve style

    Your friend should stop doing any technique immediately that is associated with pain. If injured he should stop playing and see a well qualified Dr. There are complex posture issues that might be involved also. A better approach is to compare two clear high speed videos and look for...

    Game of Tennis & Players vs TV Where do new tennis rules originate from? To fix a problem with tennis that people become aware of. I believe that many rules associated with timing, don't have anything to do with tennis but with things outside of tennis, often TV broadcasting. 1) rule - '25...

    Too Much Shoulder Rotation?

    I did not look at enough forehands. The first one elbow is straight, then some not very bent and then more bent. Federer with a straight elbow and Eastern Forehand Grip is not a good comparison for you. Djokovic with Semi Western Grip is very good and a forehand compilation of many players...
