Can you guys offer any tips? I know i need to straighten my legs, hows my height? My goal is eventually a nice and smooth roundoff-bhs-tuck/full.

Any feedback much appreciated

Good stuff. I see your head a bit out when your hands hit the ground is all. I could get on you about form but honestly on ground it really changes that.

Try to work on knees straight in the air but they are gonna bend a bit on ground.

Round off looks pretty good.

What do you have to train layouts on? A tramp or diving board into pool?

k thanks!

as far as layouts go.. pretty much I have my mat haha

I have some access to trampolines, and I can layout full on those pretty well.

Im gonna try to get to some open gym when cross country is over in a couple weeks
