Hi all!
I ve been 4 months working in the TB stretch series and still I am not able to do the last part of it (bridge work). My thoracic and shoulder mobility is the worst. When I checked myself in front of a mirror doing seal and seal rock I realized my back is straight, not extended. I am trying to do my best depressing and retracting my shoulders and extending my upper back while trying no to flex my lower back engaging my abs. I m not sure if I am working properly or it s just terrible mobility. Advice would be much aprecciated!
