I am proud of the amout of time u put into getting fit,,most kids will not.To help u,try what my wife and her friend does,its cheap,easy and only takes a few times a week.
Wrap plastic food wrap around ur tummy,,do NOT wrap tightly,this must allow ur blood 2 flow freely.
Wrap it about 2 or 3 times around,work outabout 45 minutes,,just walk or jog,thats what my wife does.She does a mile 3 xs a week when she works out.
This will cause ur belly to shirnk,,after u take off the plastic wrap after ur work out,,,sweat will boil off ur stomach.!!This helps keep muscles hot and lossen them up for better blood flow and tone them for a stronger tummy line/ reducing ur belly fat.
Drink plenty of water,since u will be sweating it out,,do over do any work out,if u feel like u need a break,,take one,ur young and trust me,,dont worry about what people say of u,because,,they will be the ones who proably wont make it in life,,u will,take care and god bless.
