Good, make sure you do your homework before you hand over your money. It's best that you go meet the owner of the gym, if you're comfortable with him you'll probably be comfortable in that gym.

Also in the first week find out somethings about the resident trainers. What are their successes with amateur/professional trainers. Keep your best interests in mind while finding things out. Is the trainer liable or is a lot of fighters he was with switching to others.

You also want a place that can offer what you need to know, it really helps to have a trainer that knows what he's talking about. And another thing stay away from the places where the trainer doesn't give much attention to guys other than their star pupils.

Good luck with that.
