This is the gym flooring we use at the Garage Gym Reviews headquarters, along with the 18 millimeter Achieve, and we absolutely love it. The Forge is actually a more affordable version of the Achieve flooring, and should withstand just about anything you throw at it.
Ours has been sweated on, had heavy barbells dropped on it, and had exercise bikes and treadmills dragged across it. Not only has it held up, but the 12 millimeter thickness has proven tough enough to protect the sub-flooring underneath. It also provides shock and noise absorption, as well as excellent grip to keep you sturdy no matter how strenuous your workout gets.
If you’re looking for a high-performance gym flooring option, look no further than this. Just be aware this is actual flooring, and not mats that can be moved around from place-to-place.
