I dont know if its relevent,
But the Marines dont do what i call "stress strecthing" any more apparently it can have a anethsic (again sorry for my spelling) affect on the body, and doesnt really 100% benifit you.
The technique they use now is by running in a circle, and doing various things on order. For example 1 - Jump up and head a imaginary ball, 2 - Right hand down, 3 - Left and down, etc etc.....so whilst we are all running around when the command gets called you do that particular motion.
Before i run, i do the same quick warm up.....yes on my own! Working up from my feet, then back down.
Then you can do your "strees strectching" strecthing if you so wish becasue the body has a good flow of oxygen, etc to its muscles.
I take a spinning class, and before we do anything i run through this routine.
