X-Force provides individuals with an excellent way to get fit and stay in shape, as it helps achieve greater muscular mass and strength, while spending less time at the gym. Results that previously required several workouts a week can now be stimulated in one workout a week or less. We were the first X-Force facility in the U.S. and are it's exclusive location in the Northeast.

The fundamental point of X-Force Training, compared to other forms of training, is to deliver a combination of static, concentric and increased eccentric resistance. Early machines utilizing pneumatic or electrodynamic resistance failed to provide this combination. The first machine to be constructed was the Eccentric Jo-Jo, developed by Swedish strength training physiologist Per Tesch at the Karolinska Institute in Stockholm.

X-Force is the most meaningful advancement in strength training in the last 30 years. A patented "tilting" weight stack allows for a 40% heavier resistance on the "negative" (lowering) part of the exercise. This heavier negative resistance yields a deeper inroad (depletion of starting strength), necessitates a higher intensity of effort, and results in greater strength gains over less time.

Recent research has now proven that the eccentric training found in X-Force Fitness Machines improves muscular strength and muscle growth better than concentric training. As such, X-Force eccentric training can be expected to deliver far better results in regard to the development of tendons, ligaments, joint surfaces and skeleton - and the way fat is metabolized.

Eccentric strength training is recognized as a principal cause of DOMS (delayed onset muscle soreness). Simply by increasing the intensity in the eccentric phase (instead of decreasing it) a person training eccentrically will be able to work out less frequently and in shorter bouts. Attempts have been made to apply these facts in commercial gyms, but up until now no machine has been able to provide a precisely regulated eccentric force combined with concentric and static components in the correct proportions. The X-Force is the first machine that actually meets these requirements.


Applying the full potential of the X-Force operating principle reveals several benefits. For example, research shows that a properly trained muscle takes from 48 to 92 hours to recuperate and be ready for another bout. The stronger you are and the more intense your workout is, the greater the need for rest. Our predictions indicate that a highly motivated person will require a rest period of ten days in order to recover completely! The case for X-Force is strengthened 1) by the fact that training with this system also helps regenerate passive tissues (bone, cartilage, ligaments and tendons) and 2) by the way it accelerates recovery from injuries.
