Weider X Factor.
The Weider X-Factor lets you get a total body workout from your own home. It attaches to any standard door and allows you to do more exercises at home than you can at the gym.
With the X-Factor you get progressive resistance that exceeds 210 lbs. The harder and faster you move, the more resistance it supplies, so your muscles will always stay activated.
You can work out every single muscle in your body and get ripped, toned, and sexy. The X-Factor uses explosive moves to help tone your lower body to get long, lean legs and strengthen your core to build rock hard abs.
