Hello all, I have been doing the thoracic bridge series religiously for around 4 months now. When I started I struggled, and still do, with thoracic extension and shoulder flexion. I feel like my body is starting to open up finally. I would like to ask you to critique my form on the bridge wall walk so that I can perform them more efficiently. I feel I am really close to performing this movement without aid from the hands. It seems my lack of thoracic extension is making this very difficult. Any advice is appreciated.
