I´m 14 I will be 15 in 4 months. I weigh 149 pounds and I´m 5 ft and 10 inches. I just wanted to know what the best way to get a six pack was. I tried starting on my own by doing 100 sit-ups every day and after about 2 weeks I increased it to 200 sit-ups per day. After of about a month of doing this I started seeing results, but my dad told me I was doing my sit-ups wrong and that they wouldn´t work (I would do it on the floor and raise my torso, also when I looked in the mirror I would see a six pack when I was in the middle of a sit-up).

I just need some help to see what the best way was and if I was doing my way wrong how to correct it.

Please and thank you :P
