Simms Fitness, Albuquerque

Simms Fitness keeps things simple. Instead of a big, labyrinthine gym, there's an open, no-frills space with everything you need for a quality workout: free weights, functional strength-training equipment, and mirrors for perfecting Jack LaLanne–style flexes. But make no mistake—simple doesn't mean boring. In addition to full-body circuit training, the schedule features fun latin hip-hop cardio sessions and flexibility-boosting Ashtanga yoga classes. And to make sure busy schedules don't get in the way of fitness regimens, the gym opens at 5 a.m. and closes at 10 p.m. during the week and stays open a good chunk of the weekend.
