Hi everyone...I'm a pretty small person but I have never been in shape. I am 5'2 and although I wear a small size in clothing I still have a pretty high percentage of body fat I think- my body is soft especially in my thighs and stomach. I think my "ideal weight" would be just a little bit lower. I'm thinking that losing 5 lbs through exercise would be enough for me, but I seriously don't know how to do it! I've never been one to work out hahaha I have bad knees so can only do the elliptical trainer machine at the gym.. But how often should I be working out? How long until I would see results? How often should I be doing cardio v. weights? I'm so baffled and would appreciate any help. Thanks!
