Revolutionizing Gym Training

Handy Gym™ is a patented training device based on inertial technology (a.k.a. flywheel technology). Weighing less than 2 lbs and sized at 7.8” x 5.5” x 4.3”, it can generate up to 220 lbs of resistance. Handy Gym™ supports full body training with 21 accessories. You can train indoors or outdoors using the anchoring systems designed for home, office and the gym. Handy Gym™ comes with an app and a user manual that gives you the best training.

“Exposure to eccentric overload of the upper limbs is of particular interest in overhead sports such as Baseball and HandyGym’s unique flywheel design enables coaches to explore a wide variety of exercise options. The small dimensions and portability make it an ideal tool for teams and athletes that spend large periods of time on the road, which is often the case in North American leagues. Overall, a great innovation in the field of inertial technology.”

Superior and Most Affordable

Handy Gym™ uses NASA isoinertial technology to offer functionality and efficiency comparable to expensive inertial pulley. This strength training method is independent of gravity and superior to large gym machines. It was developed by NASA in the 1990s to prevent muscle loss in astronauts during long periods in space.

Isoinertial technology supports resistance workout anywhere without lifting weights. It offers stronger and safer fitness results than conventional weights.

Handy Gym™ is also the most affordable inertial training machine in the world.
