San Diego Core Fitness Outdoor Workouts & Virtual Training

Interactive sessions run in 15-, 20-, and 45-minute formats alongside micro workouts, targeting mobility, flexibility, strength, and endurance. Coaching is anchored by Justin Fassio—an ACSM-certified trainer with 27 years of experience originally certified as a U.S. Army Master Fitness Trainer—alongside instructor Rachel in a supportive setting. Routines rely on a mat, resistance bands, and body weight, extending into customized conditioning plans and a 21-transform nutrition program centered around a 3-day juice fast.
