Unfortunately flexibility is something the vast majority forget.
I hadn't logged on for awhile but did a hard workout Friday that was from cross fit football.
At the top of each minute you complete: 5 burpees Max rep thrusters at 135 (I did FS only as my shoulder is bad), until the minute is up. You then start the next round with 5 thrusters again. You keep going as long as it takes you to get 100 thrusters/FS. 22:02
Was hard as hell and I thought I would be sore Saturday but I wasn't.
