Housed inside San Diego’s oldest surviving fire station—the renovated Fire Station No. 9—South Park Fitness operates its gym and personal training center at 2211 30th St in the 92104 ZIP code. The century-old structure retains its original vaulted ceilings and oversized engine-bay doors, and members adding flexibility work to their routines can walk to Yoga Box at 3964 30th St. Equipment spans free weights, resistance machines, a heavy bag, a semi-private indoor flexibility studio, and a rear outdoor yard for fresh-air sessions. Clients recovering from high-intensity training can book soft-tissue work at Palms Spa on 30th St. The personal training program designs periodized plans for body-recomposition clients, endurance athletes, and older adults rebuilding functional strength and balance.
