Have a Question for Me?

It has to do with keeping the hips properly aligned as much as anything else. The best is to experiment and feel what it does. When your arms reach the bottom of the drop your weight should be about equal on both feet. Try it. Any Fed clip in the archives will give you an image.

Rear Foot pushoff

Thank you. I will experiment.

250 vs 500 fps slow motion video problems

Hi John,

Something is off in the 250 fps and 500 fps videos of Roger Federer. Quicktime is great to study each element of the serve by right clicking and advancing one frame at a time.

In both the serves, Federer is in the air for 164 to 168 clicks. If the second video is at 500 fps, shouldn't Federer be in the air for roughly 164 x 2 clicks?

What am I doing wrong ? Love to hear your thoughts and keep up the great work. Your website and articles are awesome.

TF,

Neither you (nor Roger) is doing anything wrong! The problem is ours. Those red shirt high speeds of him should all be labeled 500fps. Roger is nothing if not consistent.

Thanks and great catch!

Guideline for Unit Turn Initiation Moving Forward

Curious as to your recommendation as to when a player should initiate the unit turn when moving forward. It seems that if a player is one or two steps from the contact point in to the court, the unit turn should be started immediately. If more than two steps, one should run first and then initiate the unit just before getting into a balanced set up position. Does that sound right?

Yes! But I would say is teach it as immediate. Feed the close ball. Then the shorter one and see if the timing doesn't adjust. It's always dangerous to suggest conscious preparation delay...

Unit turn /moving in to court

Any video you can suggest in this area would be helpful. Thanks

I'd just look thru the short balls for Fed, Novak, and Rafa and you should see both options.

Speed of racquet on volleys

John, I have started to look at the videos that relate to moving into the court and when the unit turn starts. I am getting a better feel for those shots. Thanks. This is my coaching season, and questions keep popping up. I have a female player who really is a good volleyer, but her volleys need to be crisper. Do you ever teach just moving the raquet faster through the hit to create a crisper shot? She is like a slow handed karate chopper. Or, is most of the power from the weight transfer? Any thoughts?

Ralph

[johnyandell]

The power is from the turn and the use of the shoulders. A rotation forward on the forehand, and the extension of the delt on the backhand with the correct hitting arm structures.

Look at the volley articles in the Advanced Tennis section:

It's analyzed and explained pretty clearly if I do say so myself...

Hi John,

Enjoyed the series by Rick Macci on the ATP forehand and backhand. His presentation was great as expected.

Are there any plans for an ATP one-handed backhand?

Thanks in advance. If a missed something on the subject from another post I apologize.

Gordon,

I do think Brian and Rick will get around to it, but with their heavy junior emphasis, the two-hander was what Brian studied first--and this led to Rick's teaching progressions.

We are going to start a new one-hander series though that is gonna be great from Christ Lewit.

Back leg push-off

Hello John,

Just a quick follow-up to the backleg push-off that I asked you about. I came across a couple of tips. One was a Mark Kovacs tip to coil into my right hip. That has helped. A second tip came from Jarmo Ahonen from an ITF site. He suggested to pivot the back foot when pushing off and feel the heel rising up and the pressure going to the right toes. I am getting better at it. I am assuming the weight then goes to the left foot where a second push occurs.

The hip coil I will buy. The rotation of the foot happens but I wouldn't think of it as a cause. Load and then let the swing uncoil you. Speaking of the left foot, not sure what you mean. What stance?
