Is this possible you fitness people?

So, I go to the gym 3-4 times a week. and im a pretty active person.

I'm 5'7" and currently about 131 lbs.

But thats the weird part. I've been going about 2 years now. But I was 120 lbs when I started. And stayed that way for a year and a half... well, with about a 4 lb variable.

But recently, like in the last 5 months I've put on a steady 8 lbs.
And my diet hasn't changed, and my workout routine isn't really any more intense. I can tell im getting in better shape, but I haven't intensified it much. But I've gotten the weight.

I dont look fatter. All my clothes still fit fine, if not filled out better. (My butt starts higher than it used to;) hahah).
But, it doesn't look like I have more muscle either really.
Would a mildly added intensity boost me up that much?

Have your muscle/fat ratio measured in the gym. If that is OK and within range, everything is OK. 8lbs is only 4 kg. If that is muscle situated in the big groups (like your legs), you may not notice. So stop worrying and measure.

Hope you had a positive result :-)
