Getting back into the gym

Hi all! I'm 30 years old, married, and a brand new registered nurse (just passed boards - start my job soon). I'm also a mom to a wonderful little 2 year old girl.

I'm not new to fitness, but it's been a while since I stepped foot into a gym. I joined our local YMCA recently, and I'm happy to be able to get back into lifting weights! I'm happy to say that I've been able to get back into lifting quite easily, and I'm hoping that I will be able to get back some muscle strength and lose some fat.

Is there a group/board/whatever out there for people who like to focus on weights? I do cardio, but it's not my focus.

Thanks!
