ChinUp

ChinUp
The ChinUp Posture Corrector was designed to help improve posture and reduce back pain. It’s a brace that fits around your upper torso to help straighten the muscles in your neck, back and shoulders.
It works by making it uncomfortable for you to be in a slouching position so you are forced to straighten up, which then helps to retrain the muscles in those areas so they will become strong enough to maintain the proper alignment on their own over time.
ChinUp available online and in Bad Backs stores.
