How long will it take me to get a six pack if i do 60sit-ups in the morning and 60 at night ?
Doing the sit ups is good and will help. You will also want to make sure you are doing something with Cardio to help keep the fat off. If you want a good six pack you will need to change up your diet. Eat good, healthy whole foods and cut out junk food. This is one part of your body that relies a lot on diet (what you eat).
