Does anyone have any experience using a bowflex machine? I have been working out with free weights at home for 10 months. Besides getting boring, since upping my dumbbells to 40 pounds my elbows and shoulders are getting sharp pains at the beginning of certain movements. I briefly tried a bolwflex machine at a local store. It seemed very comfortable. The pros that I can see of this machine is you can do lots of different exercises, it has a small footprint and it seems relatively safe. On the downside it is a little expensive. Any comments or suggestions would be greatly appreciated.
