North Park’s only boxing fitness studio doubling as a certified Rock Steady Boxing affiliate for Parkinson’s disease, BoxFit trains out of 4101 30th St, Suite B, in the 92104 ZIP code. Clients drawn to combat-based movement can expand their martial arts training at San Diego Aikikai on El Cajon Boulevard. Every 55-minute class follows a no-contact format that rotates through shadowboxing, heavy-bag intervals, one-on-one mitt work with coaches, and full-body strength circuits set to curated playlists. Muscle recovery after high-intensity rounds is available at Anahata Massage and Yoga on 30th Street. The gym’s most specialized program is its Rock Steady Boxing class, a research-backed regimen designed to slow Parkinson’s symptom progression through forced high-speed mitt combinations, cardiovascular intervals, and balance-focused footwork drills.
