That's tough. Any gym I've ever been in the regulars would offer all the help in the world to any newbie. The toughest thing in the gym is walking in the door, you get that far you're IN!

(ok, well, one story exception, my first weeks in college I looked up where there was a gym with exercise equipment and walked in. there were others there all much bigger than me. old guy came over and challenged me being there, thought I was a high school student from off-campus, I said no, just a freshman. turned out it was the football team in there and he was the conditioning coach or something, he muttered something and walked off - but I didn't use that gym much the rest of the time I was there, lol. fwiw the team did win the Rose Bowl that year!)
