X3 Fatigues Muscle Faster Than Weights
Weights overload joints and underload muscles, limiting muscle growth. Now, there’s a better way.
With variable resistance training and X3, you mirror your body’s natural strength curve: higher forces in your strong range and lighter forces in the weak range.
Variable resistance is the most effective way to build muscle, and X3 is the most powerful and effective variable resistance training system created.
- More resistance where your body is stronger
- Complete muscle fatigue for greater muscle gains
- Over 600 pounds of available force
- Full-body muscle-building workouts
- Less risk of injury than traditional weights
