If you expect to be able to take hard punches to the stomach you must develop your deep inner core muscles. this takes a lot of work and commitment. Your deep inner core muscles support your entire body. I do lots of slow crunches and leg lifts. Conditioning and breathing take time to learn and develop as with anything, patience is the key.
