To see this actual exercise, you can find it on my INSTAGRAM feed:
FIRE WALKS: I don't know what they are called but it's what I call them cause if they don't set your flutes on FIRE then you must have buns of steel (or you are doing them wrong).
-Stand on a resistance band with feet barely shoulder width apart.
-5-10 steps right pushing the band out with a knee drive across when you switch directions.
-5-10 steps left.
-2x each way
-For the burn, in place drive your knees across your body pushing your legs out, back and forth until your buns are smoking.
This is a great little extra credit move to throw in on your leg day between exercises.
