X-Force is a completely new patented method for negative training. The machines feature a radically different construction, which makes their feel unique but at the same time, achieve much better results.

By tilting the weight stack 45 degrees on the positive motion, it results in a 40-percent heavier negative stroke. This ensures a higher level of stress per motor unit, which supplies greater stimulation of the muscle fibres involved and works the entire joint structure, which results in more strength, stability, range motion and healing process. Research clearly supports that negative (eccentric) training significantly improves muscular size and strength.
