Here was just 1 of several impossible but possible workouts.
Load a back pack with 65lbs.
Crawl 100m with pack, quickly take it off and do 20 360 degree get ups. Note: 50m there and back can substitute for 100m straight.
Do it for 800m of crawling.
A 360 degree get up is:
Tuck jump to a push up back to a tuck jump falling back and roll with feet landing about your head or behind you followed by with momentum getting up no hands.
