SUPPORT DEVICE FOR ASSISTING TRUNK EXERCISE INCLUDING COUPLER FOR WEIGHT TRAINING MACHINE}

The present invention relates to a torso exercise assistance device for a weight training machine that can stably support the user's torso.

As interest in health has recently increased, interest in weight training is also increasing. In particular, along with the well-being craze and body fitness craze, strength training as well as aerobic exercise to reduce body fat are attracting attention.

Muscle strength refers to the ability of muscles to exert force. Strength training aims to increase muscle size and increase motor units so that multiple muscle fibers can be recruited simultaneously for exercise.

Exercise equipment for strength training can be broadly classified into two categories.

The first is exercise using body weight. Exercise using body weight is a basic form of strength exercise that uses one's own body weight without using any special weight equipment. Examples include squats, lunges, and push-ups.

The second is exercise using equipment. Exercises using equipment refer to exercises using various equipment such as weight machines, Smith machines, weight pulley machines (or cable crossover training machines), etc.

However, conventional weight training machines have difficulty firmly supporting the torso and maintaining correct posture, so the need for torso exercise assistance devices has emerged.

For a specific example, a weight pulley machine generally fixes a variable weight stack on one or two vertical frames, connects the weight stack to a cable through a pulley, and allows the user to hold a handle connected to the cable. It is a device for performing post-exercise exercises.
