In the follow along video of the Thoracic Bridge Stretch Course Coach says that a lot of people are weaker at pushing than they are at pulling. I find this to be true (at least it is for me) but I've always considered it a normal thing. The back muscles that are involved in every pulling movement are much larger than our pushing muscles (just think about the size of your lats compared to the size of your chest), so it makes sense to me that we are stronger at pulling. I also think that is kind of a genetic thing: monkeys are always hanging and moving between branches using their pulling muscles, but I guess this is a little bit of a stretch since their posture and anatomy is different from ours. Any thoughts about this?
