More Information

The man lives among 1G gravity

Man’s backbone shapes like the alphabet S and was created to endure the gravity while standing along with our evolution processes. When we sit down, we tend to lose the tension around the muscles created by the s-curve of the backbone and power for the bone structure working together. Especially, when handling pedals on driving, it causes lack of muscular strength holding back bones and symptoms such as back or lower back problems and stiff shoulders. Also, it becomes necessary to maintain the right posture with the correctly functioning back while sitting.

Two Functions

1.Dispersing body weight on the back

Normally, when being seated, the muscles around your back get loose and upper body weight directly burdens on your back. This causes the tiredness on your back and pain while driving, and it is necessary to disperse the weight on your back.

When you use Back-to-Back Genki-kunTM, your muscles on your back get pressed outward and get the body weight dispersed. It gets close to the condition as standing, gets easier to absorb the weight to the backbone and disc areas, and reduces the burdens to your back.

2.Preventing the burdens on you back from using foot pedals

Consecutive pedal operation while driving puts unexpected burdens on your back.
Using Back-to-Back Genki-kunTM reduces the burdens on your back from pedal operations, tiredness on your back and joints, and back pain.

The two functions above are based on the body shape seen from the top (plan view).
