Anyways, i have started to do 100 sit ups a day, drink only water, and stayinf away from sweets and sugars. I will start to run for about 30 minutes once my ankle is better for about a week, then step up my time. I ride my bike just about everyday. I usually eat two eggs every morning for breakfast. I usually dont. Eat lunch becuz there food is all fatty ... Then when i get home i have a small snackk. For dinner, its usually a small meal such as grilled chicken, small low fat mini pizzas, etc. This is the first time im really taking this whole thing seriously.. So pkease give me some exercising tips that will really help with flattening my stomach. Please exscuse any misspellings, im on my ipod!!(: thanks guysss(:
