For a movement that builds muscle and burns fat simultaneously, try the Gyro Grip. Simply exert force to rotate the Gyro Grip’s one pound weight and experience the resistance of centrifugal force as you propel the weight at a rate of 250-300 RPM. Conventional cardiovascular workouts put painful pressure on your joints, but the high-speed repetitive movement of the Gyro Grip will increase your heart rate for a safe but effective cardiovascular exercise. The tight concentric circle will have your muscles burning in a matter of seconds, providing you with a combined strength and endurance workout while you burn calories. Workout at home, at the office, or even while watching TV. Because you control the force, you are sure to get a safe but effective workout no matter your current fitness level.
