Gravitrons

Gravitrons

— a simulator designed mainly for performing pull-ups on the horizontal bar, push-ups on the uneven bars and some other similar exercises with "relief" — when the athlete works with his own weight, but not full. This is achieved in the following way. The design of the gravitron has a movable platform connected to a counterweight — it creates resistance when the platform moves down and returns it to its original (upper) position when the load disappears. Thus, when an athlete performs push-ups or pull-ups with their knees on the platform, when moving up, the platform additionally pushes them, reducing the actual load. This allows you to slightly change the format of performing such exercises, shifting the emphasis from high efforts to the number of times and speed of execution; and by adjusting the counterweight, you can choose the optimal balance between strength and speed. This feature is especially important for novice users, who often have difficulty working with full body weight (especially if this weight is large). And the main muscle groups worked out during such training include pectoral, dorsal, deltoid and arm muscles (biceps or triceps), depending on the technique.
Other options for using gravitrons are also possible — in particular, pumping the buttocks, when an athlete, standing with one foot on the floor, presses with force with the other foot on the platform of the simulator.
