Most strength equipment is built out of metal tubing. Gauge measures the thickness of the metal that composed the tubing. A lower number of gauge corresponds to thicker metal while a higher gauge number equates to thinner metal. Most low end fitness equipment, “Sears specials”, start around 14 gauge which equals a metal wall thickness of roughly 2mm.

The heaviest and most robust fitness equipment goes to 7 gauge or higher with metal wall thickness of 4.5mm+. Take a look at our Comparitor Matrix to see what gauge some of our top competitors are using. The frame tubing on the X9 Hybrid Gym is 4mm thick with some parts going higher than 10mm thick!
