Is there a longer or wider X3 bar?
This is by design, a longer bar ends up making the exercises easier. This doesn’t equate to better stimulation of the muscle. A wider grip ends up decreasing your range of motion, which means less stimulation, therefore less growth. The X3 is designed to stimulate the greatest amount of growth.
We don’t have any plans to make a wider X3 bar. The width of the X3 bar is sufficient to trigger extreme muscle growth for virtually anyone, and as shown by the X3 community the current size is convenient for travel and storage.
