The first time I do the bridge series I stopped here. I was completely beat, and I couldn't even hold a HS. Today is the 2nd time (after like a couple months, lol, cuz I was so discouraged), and I got passed this point! With the help of my feet, I did a few shoulder flexions. As I get better, I won't use my feet to assist. Other than that, is the flexion ok? Thanks!
