Chalean is kicking my butt!

I started the Chalean Extreme program on Monday and man oh man, its rough! But the accomplishment I feel after the workout makes it all worth wild, at least until the next day when I can't make it up or down my stairs! I'm hoping her method of lifting extreme heavy weights is gonna work, ok I'm gonna be positive, I know its going to work! Looking at her and her sister there not bulky at all and they lift heavy, there's even a lady on the videos that you would never guess is 60 and looks fabulous!
