Workout Like An Astronaut with the Handy Gym

Friction training is a kind of low-impact training used by astronauts that will work great for travelers & their hotel room workouts. Or really anyone seeking full-body concentric & eccentric workouts. The Handy Gym weighs just 2 pounds but uses something called isoinertial technology to make the 2-pounds really work you out with over 200 different exercises.
