Introducing the new PER4MAX X-Fit ! The X-Fit adds functional yet discrete additions to the chair that allows CrossFit athletes to achieve a more dynamic workout. With an integrated kettle ball loop and removable fifth wheel, Crossfit athletes can get the desired weight and stability required to complete their eXtreme workouts! We also incorporated barbel supports capable of holding 400lbs plus to the front of the chair that swings away when not in use. If you have X-Fit needs contact us as we are happy to make your ideas a reality with PER4MAX X-Fit!
