the 'handy gym' is how NASA's astronauts keep fit in space

it’s a little difficult to lift weights in space so how exactly do NASA astronauts keep fit? the answer is friction training, a low impact way of working out that utilizes friction technology and works in zero-gravity.

presented in the form of a two-pound, contact accessory, handy gym contains two inertial discs capable of converting its turn in strength of resistance. it uses the NASA-developed isoinertial technology to offer functionality and efficiency comparable to expensive inertial pulleys and other large-scale gym machines.

isoinertial technology was developed for NASA in the 1990s to solve the problem of loss of muscle mass suffered by astronauts after long periods in space. independent of gravity, this training method exercises muscles in both phases of movement: concentric (when the muscles contract) and eccentric (when the muscles extend). 

the handy gym is a compact training device that weighs just 2 pounds and is small enough to fit into a suitcase. it also comes with a wide variety of gripping elements that allow you to perform up to 200 different exercises and work any muscle group you want.

three steel discs offer three level of intensities, ranging from low to medium and high power. furthermore, it features a bluetooth module too that lets you track your progress as you exercise, while the app even guides you through using the tiny multi-purpose device to work all parts of your body.
