I always had poor posture.
I have a light form of scoliosis, other people in my family have it also but they seem to stand straight while my shoulders are rounded and my stomach sticks out.
When i do only pull ups and swim it seems to be better but when i skip rope or run for ex it gets worse.
The strange thing i noticed, when i do crunches or sit ups and especially leg raises my posture gets really bad,
it looks like i have a huge stomach/ belly sticking out, a cavzman look you might say...
Does somebody experiences this also and know any corrective exercises? i want to build my abs but cant do them due to the effect on my posture
