text: what do you do when excersise doesn't work? ok so i'm 17 and i weigh ...ok i'm a girl and i'm not telling, but a lot and i really need to lose weight. not only do i need to but i'm a high school senior and winter formal, prom and graduation are right around the corner and i want to look great. but here's the thing, i try to hit the gym at least 4 times a week and i'll do about 45 mins of cardio and i'm slowly getting into the weights and machines like those but my weights not coming down. not only that but i can't seem to actually stick to any plan i make for myself. like i said, i'm only 17 so i'm really tight on money and there's no way i can get a personal trainer. i need to lose weight and i need to do it now. i'm hopping for 40 pounds my may. is that too unrealistic and how can obtain my goal? sorry, this isn't really any help, but i have the same problem.. i've been doing regular exercise, including weight training and cardio for months, with a personal trainer that i see every two weeks, and i haven't lost an ounce! my trainer says i'm probably losing fat and gaining muscle weight, and the same goes for you i'm sure, but any addiitonal weightloss has to come from a healthy diet and drinking lots of water, according to my trainer! good luck, i know how hard it is!!!
