gotcha. i agree it totally works.
I've used our blue folding mats to do the same progression with adults during our saturday programs. the mats work out well because each fold is 3" so there is a very small level of progression. a woman that trained with me went from not being able to do any pushups on the floor to doing the 12 pushup pyramid from trainforstrength.com on the floor in less than 3 months if I remmber correctly.
there is still an issue of trying to get all things accomplished in just 2700 seconds twice a week. I think we are going to start isolating an exercise every week and rotate through every three weeks: pushups, sit-ups, squats or I'll try to figure out how to get 10 kids through all of it in 10-15 minutes.

It's simpler than you think.
I could be completely wrong"
