What is X3?

X3 is the breakthrough patented training technology that delivers variable and adaptive resistance to achieve a greater effect in your training, with more muscles involved in the exercise, over each part of the movement, while maintaining stability and protecting the joints.

  • Don't Just Take Our Word For It

    Build more muscle with less risk of injury and burn more fat in far less time. With X3, all you need is 10 minutes, the X3 Bar system, and a small workout space.

Why is X3 more effective than traditional weights?

Research showed that X3 builds muscles more effectively than traditional strength training, which we know from e.g. the fitness centers.​

Maximize muscle growth

With X3, the weight increases as you move from the weak zone (start of the movement) to the strong zone (near full extension), where you are able to produce 7x more force. This allows you to safely train with greater force than you would with weights, triggering greater muscle growth.

All you need is one set

X3’s strength training program is not only less time-consuming but also significantly reduces the risk of overloading joints, which is most often where the problems arise, during heavy training with free weights and machines, because they do not use adaptive resistance to the same extent as the X3 system.

  • Caleb Demmons

    "I started at about 190 pounds (86KG) in March. Today I weighed in at 173 (78KG). Being light but strong is exactly what i need and X3 has helped me skyrocket my results and training. As a professional parkour athlete, regular weight lifting always left me too sore. With X3, I can lift as heave as possible and jump right into training afterward. I'm never sore and I perform better. X3 is the perfect supplement to my training."

  • The X3 resistance band bar delivers variable resistance to match your body’s biomechanics. With X3, you stimulate optimal hormonal release, fat loss, and muscle growth. It’s a faster, more effective workout.

The X3 Home Gym: Greater Force, Greater Gains

Weights overload joints and underload muscles, limiting muscle growth. Now there’s a better way. While researching bone density for his first invention, OsteoStrong, Dr. John Jaquish discovered a sevenfold difference between the weakest and strongest ranges in weight lifting.

The discovery led to the invention of X3, the ultimate muscle-building system. X3 requires lighter forces in the weak range and high forces in the strong range, mirroring your body’s natural strength curve.
