Bowflex's home gyms have become a very popular choice in a short amount of time, partly due to their focus on marketing, and Bowflex has grown into a competitive manufacturer of exercise equipment with a good share of the market.
Bowflex home gyms are based on Power Rod, bendable piece of metal that creates more resistance as cables are being pulled. This type of weight resistance works for some people, while others don't like it. It is really a matter of taste. The good thing about Bowflex and Power Rods is that the chance of injury or joint pain is reduced to a minimum.
We recommend that you try using one of their home gyms and see how it feels. An advantage of Bowflex machines is that they're cable based which means you have a wide range of exercises to choose from. Something worth considering.
