The secret to building muscle is lifting heavier and with more repetitions. The X3 bar lets you do just that. By providing more resistance as you extend, X3 lets you train heavier and fully fatigue your muscles with less risk of injury than with weights. In a recent discovery looking at biomechanics, we see that humans are 7 times stronger in the impact-ready range of motion. This shows us that variable resistance is far superior than standard weight lifting because only variable resistance will

726 reactions · 72 shares | There are 16 academic studies that prove that variable resistance will grow muscle and strength faster than standard training. X3 provides the highest level of resistance (600 lbs+) compared to any other variable resistance system. Meaning, you get much more resistance where your body is stronger and less where it's weaker. Resulting in greater muscle fatigue for faster muscle growth. | X3 Bar | Facebook
