I can sum up my thoughts on the Las Vegas Athletic Club with a yogi-ism. "No one goes there anymore, it's too crowded."
I've been a member of LVAC for 18 months and my experience at the Eastern & 215 location has been generally positive. There are an overwhelming number of different types of machines and exercise options. They also have very clear and easy to read labels about how to use each machine and what body parts it is designed to work.
The machines are organized appropriately, in good condition, and are very rarely not working. There are plenty of TV's around to keep you busy in between sets and the music video's they play are good for the atmosphere. I found the employees to be very friendly
The major problem I have had is with how crowded it can get in the free weights area. During the mid-afternoon hours you might be able to find a bench, otherwise you will have to wait or work in with someone. Any time between 4 p.m. and 10 p.m. and it is almost chaotic in that area. That being said, I have had some more luck at the Lake Mead location as it is a little bit bigger.
Overall, you can't beat the price and working out a little bit later in the evening is worth the hassle. 4 stars.
