I was just down there last week for work.....The hotel I was at had a deel with Bally's where working out was free. Gym was not bad had everything you need. Just make sure you go before 6 or after 8. It is not the biggest gym in the world
Also there is a YMCA in one of the hotels, I did not check it out but most Y's have what you need. There are alot of gyms down there so you wil find some place
