Hello. My name is Joelle and I'm a 17 year old high school student. I used to play tennis and ride horses but since then I have quit due to financial reasons and have just recently joined a gym. I met with a personal trainer for an orientation, but he was not too helpful on what to do. I currently weigh 125 lbs and I want to get back down to 115. I am a healthy eater, but am not exactly sure what to do when it comes to starting out on a routine to get a flatter belly, and firm up my legs and butt a bit. Just basically I want to be fit. Could anyone help me out and let me know what to do? I'd appreciate it a lot.
