Lights Out Fitness LLC brings boxing-based strength and conditioning training to Chula Vista's Third Avenue corridor from its Suite G studio at 1447 Third Avenue. Founded in 2020, the gym uses boxing fundamentals—heavy-bag rounds, mitt work, footwork drills, and combination sequencing—as the conditioning backbone for classes that build cardio endurance and striking power, an approach to combat fitness shared by the MMA roster at Teams MMA on nearby Third Avenue. The facility is listed on Tapology's competitive-gym database, indicating that active amateur and sanctioned fighters train alongside general-fitness members pursuing non-competitive conditioning goals. Class structure alternates between technique-focused rounds on the heavy bag and bodyweight conditioning circuits incorporating burpees, push-ups, and core rotation drills. Recovery protocols for fighters preparing for sanctioned bouts include periodized deload weeks and soft-tissue maintenance through the deep-pressure massage modalities available at Balensi Spa. Defensive-shell and counter-punching sequences train inside-fighting reflexes at close range, drilling slip-and-counter combinations that develop reactive hand speed across three-minute timed rounds.
