I don't know if you mean something else but what more can I do with legs in that video? I was getting the maximum out of my legs there. Only thing that can be better are my arm movement.
Also the fingers don't work for me. When I press with my pointy finger my thumb also presses into the blade at the same time otherwise it feels super off.
hi
@Zezima ,
sorry I did not catch this earlier.
The use of the legs, with the hip going down some, from a position where you are sitting down a little in your stance... this is the START of your kinetic chain to create energy, amplify (increase it), and deliver it to the ball...
The key thing at the end, if you were loose enough and had all those nice separate sequential small explosions... that at the end, you deliver the power with your fingers (squeeze at impact) (also make extra bat speed with middle two finger squeezing the handle and leveraging it off your palm)...
It is VERY important to figure out these final two squeezes to get that extra bat speed and delivery of power to the ball
There is also a certain pre-load of the wrist (not the flippy floppy 90 degree part of wrist, but the linear 30 degree each way kind of wrist) that creates the base to explode the wrist (then fingers, then Squeeze) through the ball.
The question you have about the legs... assuming you saw the impact right, AND get to position of leverage as ball gets to strike zone... assuming that... well then the use of legs is actually starting with the toes and foot. Then you are coming out of crouch some to amplify your power...
So many separate explosions sequential happening so fast together one hardly can discern they are separate... but they are and MUST be separate of one loses power on the shot. Often, a player is tightening up too early, either the hips or shoulder or arm... that puts the Bremsen on your chain faster that Brembo brakes on a Porsche.
Chain... from good crouched leverage sitting down a little and bowed forward a little... toes, legs up, hip up and forward, upper body turns together, upper body turns a little more than hips, then upper arm stops/slows down before impact, lower arm snaps forward (and up for loops with more closed bat face) the arm is loose and the wrist starts to go forward, then lower arm muscle powers wrist forward, fingers squeeze on bat handle and fast bat head speed becomes faster, and FINAL transfer of power is with finger squeeze to firm right at impact to multiply the force transferred to the ball.
That is a LOT of stuff going on... and one has to perform this without any conscious thinking, or one with tighten up the wrong part to early and ruin it all.
Assuming good enough position and leverage to start the shot...the error amateur players have is the timing of the ball (or the skill to get the ball deep enough to the strike zone), tightening and ruining the chain, or not rotating the hip enough or effective enough (or sometimes too much) and too long a backswing (makes timing much more difficult).
There is no singular correct answer to your question... and actually even more questions for you to ask yourself and figure out.
You can look at mirror and try to shadow stroke and see for yourself, but that is usually not a realistic rally or match shot, so ultimately, you have to look at your video making and see it for yourself.
What you have going on is inefficiency in your chain.
If I or someone else makes the comment that you are getting down, but not up during your shot, then you are not using legs enough or right.
If someone says you are using too much arm (and/or shoulder) then you are NOT slowing down upper arm before impact and allowing the lower arm to snap.
Often, amateur players tighten up should and the energy flow stops there... then player over uses shoulder to try to make that energy... and fails... and often sets themselves up for a major shoulder injury down the road in the future.
If someone says your stroke looks well enough... but there is a big lack of spin and pace... then there are problems with the wrist snap and use of fingers to whip the bat head and squeeze to transfer power... also amateurs ruin their transfer by tightening arm or wrist too early, which stops that power and delivery.
Again, so many things going on... and when you get a good understanding of how the chain works, you will both SEE (on video) (or in the mirror) (or if you see this on other players) and you will FEEL where something goes wrong.
Again, no immediate quick answer to your issue(s) but things to look for and help yourself.
You are brave to video yourself and post here... and also smart/determined to improve.
