Billy is a great trainer and the gym is friendly and welcoming. This is where you should go in Las Vegas if you're serious about lifting weights and making real improvements to your technique. I found the olympic weightlifting classes very helpful in my development as an athlete and "next level" relative to a number of the other programs in Las Vegas.
As a huge bonus, Billy is actively engaged in the whole class. As a member of a number of class-oriented gyms, I know it is easy for the coach to zone out or talk to members who aren't in the class--to become distracted from helping the class improve. That just isn't what you get at Las Vegas Barbell.
I definitely recommend this place.
