After overcoming Legg-Calvé-Perthes Disease as a child, a condition doctors said would prevent her from running, gymnastics, or weightlifting, Niki Zager founded NZ Fitness as a personal training practice at 2949 Garnet Ave and 5115 Soledad Rd in Pacific Beach, 92109. Zager holds a Personal Training Certification in Kinesiology and Exercise Science from the International Sports Sciences Association (ISSA) and serves as an NPC bodybuilding coach and posing coach in addition to her one-on-one training work. NZ Fitness offers individualized program design, remote coaching, virtual personal training, tactical training, gymnastics workshops, and nutrition coaching, all tailored to each clients body composition, athletic background, and lifestyle goals. Before launching her own brand, Zager gained industry experience at Roar Ambition, Injinji performance socks, and Chefs Cut Real Jerky Co., and she brings that cross-disciplinary perspective to her approach to client wellness. She also leads seasonal HIIT bootcamp classes overlooking Mission Bay through the San Diego Social Leagues, and trainees looking for a post-workout sandwich can walk to Board & Brew - Pacific Beach on nearby Garnet Avenue. The studio maintains a perfect 5.0-star Google rating, with every one of its nine reviewers awarding the maximum score. Zagers personal story of proving medical expectations wrong has become central to her coaching philosophy, which emphasizes patience, consistency, and the connection between physical strength and mental resilience. Clients recovering from injuries or looking for sports rehabilitation support can pair their NZ Fitness training with visits to Rx Rehab And Performance in Pacific Beach for chiropractic and rehab services. NZ Fitness is open weekdays from 5 a.m. to 7 p.m. and weekends from 7 a.m. to 2 p.m.
