CrossFit Classes
Our CrossFit classes combine weightlifting, gymnastics, and metabolic conditioning to build overall fitness. Each session includes warm-up, skill development, and a high-intensity workout adaptable to any ability level. Certified coaches provide real-time feedback to ensure proper form and safety while tracking progress toward individual goals.
Barbell Club
Focused barbell programming develops strength, power, and technical proficiency in Olympic lifts. Sessions include structured progressions for snatch, clean & jerk, and accessory movements. Coaches provide individualized adjustments to optimize lifting mechanics and prevent injury while building measurable strength gains over time.
Mobility Sessions
Mobility classes use dynamic stretching, foam rolling, and targeted exercises to improve range of motion and recovery. These sessions address common movement restrictions from sedentary lifestyles or intense training, helping members maintain proper form during workouts and reduce injury risk through improved body mechanics.
Drop-In Training
Travelers and visiting athletes can participate in regularly scheduled classes for $25 per session. Reservations are required to ensure space availability, with options to cancel up to cutoff time without penalty. Drop-ins receive the same expert coaching and community support as regular members during their visit.
Membership Options
