I thought I would discuss something I have video for; The double layout on trampoline. Please excuse the poor video quality as this video is very old, however I cannot make any new videos with me spotting since I am not spotting too much right now with my arm in mechanical brace (3 weeks out of surgery, seems like a lifetime).
This double layout technique is for very young (approx age 6-10) athletes as an introductory method to help develop their kinesthetic awareness. The final video in the series is a 6 year old performing the double layout with spot.
I hope this video gives you a simplistic teaching method for an advanced skill. Please make sure you master the spotting techniques used before trying a few of the drills in the video.
Good luck and happy coaching,

Bart
