Good to see MDs still up at 3 in the morning writing his bullshit. I wont bother reading them, probably his usual drivel.
Yesterday's serves practice. Very windy day. I am fiddling with my serve, this is more my old Fed-like motion with the platform stance.
Improvements I see I need to make.
left foot move forward instead of back
more knee bend, more back bend, more body turn
As for toss, the height is fine, i am jumping, my arm is fully extended, but the toss is too far left. Needs to be more to the right.
Left arm/neck. The left arm needs to stay up longer after releasing the toss
We getting there.
thing is that you're getting the maximum from this rather wrong movement. You serve quite strong with that and if you manage to change it in a correct way, having the shoulder power that it seems you do have, you could have a great one.
First major thing to start with and seriously - it is important - the ball toss!
The way you toss the ball makes your whole movement follow up wrongly and perhaps by changing only that you could yield a huge positive change.
You throw the ball on the side, which is the reason you make this step with your left foot and spending the energy created by the twist of the body in vain.
Throw the ball straight up and slightly ahead (it should land one meter inside the court straight in front of you if you throw and don't hit it).
Have your weight on your toes, not the heels and the side of the foot, direct your movement ahead.
Just by tossing the ball right these should come by themselves.
At first the serve won't get inside the box, you'll probably hit many nets, but that's the way it should and then you'll slightly adjust your body movement toward the new toss.
Important points - 1. use the rotation of the body (when tossing be 90 degrees to the net, comletely side ways, then when the racquet starts toward the ball - rotate).
2. Drop the back shoulder low, lower than the tossing shoulder. It makes you gain momentum and height when reaching for the ball.
Start from there and if you practice enough you should feel the improvement quite fast.
But start with the toss, it's absolutely imperative.
