The back posture support device is a mechanical device that aims to help maintain the spine at the right position during squats and thereby minimize or eliminate injuries associated with poor form on the lower back region. It is designed for athletes, gym users and physically active individuals that do squats. The device does not use any electricity hence can be operated anywhere at any time. However, it is limited in the aspect of size and fit as the correct size is needed for different sized bodies and therefore people with improper fitting might experience restricted movements or discomfort while exercising.
