Through Live Free CrossFit's large front windows, exercisers can see the sunrise and the sunset. That's because trainers lead classes as early as 6 a.m., and all through the afternoon and early evening. As the sun does its own squats, students execute lunges, lifts, sprints, and jumps. A vast array of tools are used during the action, including plyometric boxes, barbells, pull-up bars, and gymnastics rings. The routine changes every day, keeping students on their toes and building muscle. The routines feature functional exercises performed at a high intensity. The functionality and variety leads to preparedness for all manner of physical challenges, be it climbing a mountain or climbing the stairs at the office. Trainers scale all workouts, making them accessible to participants from all walks of life and fitness levels. And for anyone new to CrossFit, they offer a Foundations class designed to get rookies off on the right foot.
