After years of being a Firm fan (since 1986) and doing traditional style weight training and all kinds of cardio, I have just discovered the Slow Burn/Power of 10. I'm into my 3rd week and I am hooked. I workout 2 days a week and workouts are usually 40 minutes each. I hope with more practice I will be able to reduce my time. I'm still in the learning curve. This method is so intense I feel like I workout 6 days a week. I just love it and thank God 48 Hours did that piece on it or I would never have known. Ironically, the same thing happened to me with the low-carb diet 5 years ago. Saw a piece about it on 48 hours, tried it and have been hooked ever since.
