X3 FAQ: Variable Resistance Training: What’s the Science Behind X3 Bar?
The following studies, conducted on athletes and everyday individuals, demonstrate the superiority of variable resistance training (VRT) over weight training.

We are frequently asked how to get into the proper position for a chest press.
A great majority of people engaging in “cardio” exercise do so to reduce their body fat yet this has an impact that runs counter to what they want.
Why do we only perform one set of each X3 Bar exercise? With variable resistance, specifically with X3, one set is all you need to reach complete fatigue.
How is X3 different from typical resistance bands or static weights? X3 provides a varying force based on biomechanics.
With X3, we are utilizing variable resistance, which causes us to use significantly more muscle fibers and weight per exercise than we would otherwise.
Don’t spend your money on new fitness equipment to build muscle until you find out which is better for muscle and strength: resistance bands or weights.
We walk through a resistance band tricep pushdown alternative known as the skull crusher, an exercise using the X3 Bar for variable resistance training.
