Hello, I am new to the forum and Cathe workouts. I am just not sure where to start. I have just finished Chalean Extreme, and have seen results, so I think I'm ready for Cathe. However I still have at least 20lbs. to loose, do you have any suggestions on what dvd's to purchase? Would the STS mesocycle 1 be a good place to start? I just have no idea. Thanks.
