So recently my front tumbling has been advancing very rapidly. I have clean front step outs into round off back flip (whip, layout, flash, tuck, x, etc.). I can garner a significant amount of height on my front flips, enough to do laid out front fulls on floor. So, from some cheer coaches and a gymnastics instructor, I was told that my front tuck is at the level where I could begin drills for the double front tuck. And this is why I am here. Attached is a video of my third attempt at a double, and there are lots of flaws that I can see, but I'll leave naming them to the pros (here). Judging from the problems with my double attempt, can somebody prescribe some drills to iron out the imperfections?
Thanks.
