burpee
Or “burpie.” Either way, it’s a killer workout. Allegedly working every muscle group in your body, (sure feels like it) this move is also called “the prison workout,” as inmates allegedly find it a way to stay in ass-saving form while limited to tiny spaces.
One burpee = from a relaxed stand, crouch down, place palms flat on floor, kick feet out to put you in pushup position; do a pushup; snap feet back to where they were; straighten back up to a stand, stretching your arms above your head to finish (or jumping in the air, if you’re all hardcore). Set-wise, the idea is to do X (a reasonably achievable #), wait/stretch 1 minute, then subtract one… and so on (i.e., 10, then 9, then 8, etc.).
It’s not very easy.
Stretch first; hold your abdominals tight on the kick-back (don’t let back “sway”). One tip I use that I haven’t seen elsewhere yet: Using something to elevate the hands slightly on that initial squat/pushup, to take some stress/load off lower back & wrists. I’m using a pair of pushup bars. I’m still all hardcore, tho.
