CrossFit Classes in Boulder

Our core offering at CrossFit Sanitas. These group workouts combine strength, conditioning, and skill work to build lasting fitness. You’ll train with barbells, bodyweight movements, and functional tools—scaled to your level. Workouts change daily to keep you progressing. There’s simply nothing more effective for getting stronger, leaner, and fitter. Whether you’re new to CrossFit or a longtime athlete, our expert coaches at one of Boulder’s top gyms will help you thrive.

Endurance & Running Classes

Cardio-focused workouts to build your engine and boost performance. Our Endurance classes use rowing, biking, running, and longer intervals to improve stamina and fat-burning. Ideal for runners, cyclists, and anyone looking to complement CrossFit. In warmer months, Track Classes meet at local Boulder tracks for race prep or a serious fitness kickstart. Open to all levels.

Functional Strength Training

Build usable strength with simple, effective lifts like squats, deadlifts, and presses. These slower-paced sessions offer full coaching support, making them ideal for beginners or anyone looking to get stronger with structured strength training in Boulder—without the intensity of a full CrossFit class. For more advanced lifters, we also offer dedicated Strength classes focused on heavier barbell work and Olympic lifts.

Barbell & Olympic Lifting

For athletes ready to take lifting to the next level. These classes focus on progressive barbell work—back squats, deadlifts, bench press, cleans, and snatches. Led by a world record holder in the clean and jerk, you'll get expert coaching to lift heavier, move better, and build lasting strength. Great for Olympic lifting, technique work, or supporting your CrossFit performance in Boulder.
