I am 6 months into the fundamentals course and have made noticeable progress in all but one exercise:
shoulder walks
To put it simply, I either lack the mobility or strength to complete even one good rep. In order to perform shoulder extension I have to sit quite high in order to get my hands touching. Last workout I gave up on the walks and just sat in the extension in hopes my mobility will improve.
My question: is sitting in extension the best way to eventually be able to perform walks or are there better exercises to promote progress? I'd like to simply sub something in for shoulder walks during the upper thoracic program.
