New Girl in Weights Section of Gym

Good for you.

Good for you! Don't be afraid to try stuff out and experiment. Everybody does it, and nobody will look twice unless you're doing something dangerous.
Guys are generally very friendly and helpful in my experience. I often ask for help spotting or checking my technique (especially in deadlifting). You can learn a lot through just spending time there.

Good for you! the weights section can be intimidating with the guys in there, but is nothing to be afraid of. Good that you are getting into strength training. It will make a big difference to your definition.
Watch what other people are doing, and if you need help don't be afraid to ask someone if they look like they might be OK to help. If your gym has trainers/staff walking around, ask them TONS of questions. I am constantly stopping the staff at my gym and asking then for advice/help on my technique when I am not completely sure about something.

Take advice from fellow lifters/exercisers with a grain of salt. Most people will be moderately knowledgable, some people will know a lot of good stuff. But there also tends to be a lot of 'bro science' among lifters. If someone suggests something, take it on board, do your own checking online, and if a staff member is around, check with them. I have had a few times where someone has given me some advice on an exercise/technique and I have found out later that they have been wrong or given me bad advice that could hurt me.
