What makes 10-Minute Trainer so effective? "The secret is my breakthrough Super Stackingô Technique. It's a combination of using resistance bands and the most effective moves I know in a 10-minute workout. So instead of focusing on one particular area of the body at a time, I stack them. This gives you fatóburning cardio, totalóbody toning and sculpting, and abs workouts all at the same timeóin just 10 minutes."
