trainer at 24 hour fitness? I am 21 year-old guy and my main goal is to gain MUSCLE, not just get in shape. Right now I am 170 pounds. I used to be really skinny back in the day; I used to be 140 pounds when I was 19 years old, therefore, I decided to eat more and start lifting weights. The good thing is that I have gained a lot more weight which is good, but I am still not in shape though. For a year I have tried my hardest at the gym and did everything I could to gain muscles, but I don't see any changes. I have fat belly right now, and I am afraid if I do cardio, I will lose weight and get really skinny again. I don't want that to happen because I worked hard to gain weight. Please help, I feel like the only thing I can do is to get a personal trainer.
