I've been struggling with bad posture for a while now and constantly find myself slumping. Although my posture has improved greatly but just straightening up whenever I'm slumping, I still have lackluster posture. Will martial arts help this? It seems like it would, just wanted to know for sure from people who have experience with ma. Also, can ma help with focus? Like at work I seem to always forget something or not totally focus on whatever I'm doing. Could ma help with this as well?
