How it Works
The secret to sexy, toned arms is SpinGym’s unique “Gyrotronic Resistance Training” (GRT), developed by celebrity fitness expert and National Fitness Hall of Fame inductee, Forbes Riley. GRT engages all your upper body and core muscles, the second you start your SpinGym workout. SpinGym is designed to tune up, not bulk up.
Wave goodbye to flabby arms in as little as 5 minutes a day!
