Each body is different. I can leg press 3 sets at 360 pounds. My legs are less bulky than when I started with my trainer and my butt has a much better shape. My back and shoulders are definitely more massive from my weight training. I like it, since I was not gifted with the body of a twig. I'll take strong and muscular.
But each body is different. Talk to your trainer. He/she is the person who sees you and knows what you are doing. Presumably they took measurements when you started. You can always have them measure you again.
