Description

TECHNICAL FIELD [0001] The present invention relates to a weight training apparatus using rotation inertia and a motion method using the same,

The present invention relates to a muscle force exercise apparatus using rotational inertia and a method of using the muscle force exercise apparatus.

As the industry becomes more sophisticated and life becomes better, modern people are increasingly interested in health. Usually, various types of forceps are used to strengthen the arm, shoulder and chest muscles.

A normal force machine is a structure in which two rods that can be grasped by two hands are hinged together and a compression spring is connected to the rods, and arms and shoulders and chest muscles are strengthened by applying force such that the two rods are gathered inward. However, there is a risk that the elastic force of the spring can not control the elasticity because the elastic modulus of the spring is fixed, and when the rod is gathered inward, the elastic force suddenly unfolds to cause an accident.

In addition, in the case of exercise equipment using weight, springs, and traction ropes, the weight of the weight should be borne throughout the exercise time, and this method is very stressful for the muscular anxiety or rehabilitation therapist who needs treatment .

In addition, such a conventional exercise apparatus is disadvantageous in that it can be moved only at a position where the exercise apparatus is installed because it is inconvenient to carry and move.
