Anyway, if you have pain inside your belly and it is a kind of strong one time pain as if you are stabbed, in that case you should visit your doctor.
There are can be two reasons, you do workouts that need strong abdomen that you have not got yet. Firstly, do not put so much focus on abdominal exercises, but instead start doing workouts which do not work your abs directly. Then you can continue with a group of light, but effective core exercises such as standing ones.


Another solution can be to to do some yoga ab workouts since in most of the these moves are not so hard but still strengthen the muscles of the midsection. Overall, the answer is: start without focusing on your stomach, then do lighter exercises such as standing ones and then begin doing harder ones little by little.
Standing ab exercises are effortless to perform and suitable to build basic strength before doing others on the floor. Do the mentioned workouts for 1-3 months at least 3-4 times a week and then you can begin firmer core workouts.
