Stop forcing your back into extension like this. 😱 This assisted stretch, where a partner pushes on the thoracic spine while holding the arms, can easily over-stretch ligaments. It bypasses your muscles' natural protective response, leading to potential instability and more pain. Send this to someone who needs to ditch this risky stretch. #backpain #thoracicmobility #stretchingtips #mobilitytraining #assistedstretching
