11 year old lefty

just would like a little feed back on his pitching. He was working on knee to knee drills trying to get faster to the plate. Sorry but the song playing is what he listens to before games. Thanks for any feedback.

What are these “knee to knee” drills and why are they a good thing?

when he gets runners on base, it helps on keeping the runner close to the base or helps the catcher with the throw down. he was taking a long big leg lift and taking a lot of time from first move to catcher. He was timed at 1.7 to 1.9 and now with the knee to knee he’s at 1.1 to 1.2 from first move to catcher from 50 foot.

Slide step?

No not a slide step, my sons instructor taught him that method. It does allow load but it also minimizes delivery time. We found it very effective.
