So Im experienced and all that I can get 17 inches about down without much struggle. Sigmoid bend is easy for me now. But I use a 25 inch and every time I try to get past those inches after 17 my body starts to fight a lot. Not like painfully or anything just it starts to push a bunch even if I go slow and breathe deep. I like to lay in a side lying sims position and I’ll of course shoot live up to make it easier. Im just wondering what I could do to maybe dull that fighting.
