Fat on thighs help..?!

Me and my friend Tana have a nice hourglass shape. The other day, we were trying on swimsuits in JCP's because they were on sale. After I put on the bottoms I realized how fat my thighs are. She called me into her dressing room and I realized her thighs are as large as mine.! Anyways, after that we've been trying to think of ways to lose the weight on our thighs and belly. (We aren't too worried about our stomach because we don't have rolls, but we have baby fat and big hips) here are some questions we have and pleasseee answer them:
what can we do (such as swimming) to lose leg weight and stomach weight.?


Can the pool help lose weight on your stomach and thighs.?

Does the YMCA let 12 year olds take Aerobics/yoga classes there.?
