i'd say it's best to get a guy to workout with u as a friend. not a potential love interest. Friends should keep each other motivated well enough and there'd be no romantic pressure. If things happen, they'll happen naturally. I don't believe in trying to force relationships.

you'll have to make the first approach to talk to them. a lot of serious gym goers that knows what they're doing at gym isn't looking for friends or dating at gym. sure they'll help if you need a spotter but they'll usually go back to their own work out after you're done with the set. you can also befriend people at gym that doesn't know what they're doing either and in the long run, both of you are most likely going to be doing things wrong together with bad form. your best chance to getting someone to go to gym with you is from outside the gym, find people that looks buff or in shape like co-workers, class mates, friends, or family members and ask them to go with you to learn everything they know.
