High knees !! Ahhhhhhhhh my trainer makes me do high knees and I absolutely hate them!! But I know they are good for you!

My copy of this is on its way-figure it'll be tough but summer's coming and I need to maintain weight loss so I can keep feeling good!

LOVE IT!  :D

This is a great exercise for me to try! I have costochondritis (inflamed rib cartilage) right now, so my weightlifting is on hiatus. THUMBS UP IF YOU THINK BOB IS THE BEST TRAINER!
