Had to watch again..
She does have knee wraps on. Around 5 mins in she is doing stiff legged deads. Approx 155#s. She shows more difficulty walking back with that than with almost 495#s on her back. But, around 8 mins or so...she does one of my favorite exercises to watch and drool over...the "My head" between the thighs skull crusher! Ohhhhhh.....I so like watching those..and such good form too!
