Work Ethic Fit on Lake Murray Boulevard in La Mesa's Lake Murray corridor runs personal training and group HIIT classes from a gym suite inside the Carlson Gracie Jiu-Jitsu facility at 6195 Lake Murray Boulevard. The co-location with a Brazilian jiu-jitsu academy creates a cross-training pipeline with Jiu Jitsu Foundation athletes who supplement grappling with strength and conditioning work. Group bootcamp classes run Monday through Thursday evenings and emphasize high-intensity interval training with attention to technique and form over load. Customized nutrition and meal-planning protocols complement the training, and sports-recovery sessions at Thai Sports Massage & Spa San Diego address the soft-tissue damage that accumulates across HIIT and grappling cycles. The studio's most demanding programming layers timed circuit intervals with compound barbell movements, plyometric box work, and kettlebell complexes calibrated for clients managing long-term mobility alongside strength gains.
