hey I need some help

Im a Offensive Left Tackle in HIgh school..well was. Im 6ft 1..and I weighed 340 lbs. I went on a strict diet of running,biking,and swimming. Now I am 220lbs. I have very little fat in the upper body section. Like my shoulders, biceps, chest,and back are all pretty well defined. But My mid section still h as little bits of rolls lol.. Now for the past 4 weeks ive been much more running and biking and cutting carbs like crazy eating 5 little meals a day and Ive not seen any results in that area. I also do like 1k sit-ups after a run.

Is there anything else I can do to help me lose this to get a 6-pack?

you need to focus on your diet, go to the diet/nutrition forum and post exactly what you eat meal by meal every day.

Yes, there is no such thing as "spot reduction". You can only lose all over or not at all.

Those situps are helping You just need a solid diet and cardio schedule. Diet is key.
