Hi all.
I've been training HS stomach to wall for a week (well, stomatch never touched wall, because i feel my back too bent), i' ve been trying to maintain a hollow position. I last like 20 to 30 seconds and been training 5x15-20 seconds.
Now my hated pre-beach alter ego.
I want to increase my shoulders size, training HS stomach to wall, would you tell me the best (in your pro-opinion) way to improve it? Something like 10 sets? Without getting burned?
Please don´t be heartless. ![]()
