Thank you guys for the feedback.
@daveblt, I didn't understand what you meant by hands scooping up to the surface. Can you clarify?
@Mushroomfloat, I had actually tried keeping a pull buoy between my thighs but my right leg still went down a lot. I think I got used to this bad kick where I kick down a lot.
Yesterday, I tried to kick down only a little. But I won't know if I'm doing any better till I take another video.
