Boxing and MMA workouts will get you in shape in no time! I know this first hand as I used to go to a class that melted pounds away.
Nexersys Boxing Systems is a personal trainer without having a real personal trainer. A 19″ – 21″ monitor will tell you where to strike with punches and kicks and keep you sweating. They are going for $3,000-$7,000 per so make sure you really want it.
