Interesting lunge analysis from Gold's Gym

The image at left is from our most recent exercise analysis of the lunge on the Smith Machine at Gold's Gym, Ann Arbor.  The drawing shows the basic leg positioning at the start of the exercise (yellow) and at exercise's end (orange).  This type of analysis gives a good perspective on the movement's basic elements.  It also shows how well form holds up over multiple reps.  We'll probably use it again.
