This AlterG treadmill is gently used and in great condition, perfect for rehab, low-impact workouts, or performance training. It lets you adjust your body weight to a chosen percentage (i.e. walk with 20% of your body weight), making walking or running far less painful and ideal for recovering from injuries to your legs, knees, or feet—and you can also set the incline for added training versatility. Reduce joint stress while maintaining your fitness routine or recovering safely. Ideal for athletes, clinics, or anyone looking to train smarter. Comes with 7 pair of Alter G Treadmill Shorts.
