Your best bet to lose body fat and tone up is to provide your muscles with resistance. But not just resistance, a VARIETY of resistance. The Bowflex machine (which I have tried) provides a large range of exercises for the entire body with a wide range of different resistant levels. Unlike conventional weight machines at the gym, the resistance bars also enable you to build a lot of stability in your muscles which targets the small muscles around your joints. Therefore, the more muscles you target, the more calories you burn, the more toned you get. And because the Bowflex has such a huge variety of full body workouts that come with it, having consistent muscle confusion gets people great results when they change up their routine on a regular basis. Again, with any exercise regiment, proper nutrition and clearance from your doctor is a MUST. Bottom Line – The Bowflex – Doctor’s Thumbs Up.
