REX KWON DO! I beleive he stretches at least 3X a day. Stretch often and kick ass! You too can be kick like Rex if you STRETCH YOUR HAMSTRINGS! Flexible hamstrings are a priority so that you and your "Starla" can:
be free from back pain.
have a more mature squat.
prevent injuries especially in the knees.
12 Minute time limit.
Run 1 Mile
Then perform as many body weight front squats as possible.

"Rex Kwon Do" costs a little less than CrossFit, but at least we won't make you wear those pants or smack you in the head.
