Chain Reaction Fitness & Nutrition

At Chain Reaction Fitness & Nutrition, we help San Bruno and the surrounding Peninsula residents reach their fitness goals with personal training, group classes, and nutrition plans in an uncrowded, well-maintained space. Our gym is stocked with a wide range of machines, attachments, and free weights, so there is equipment for every type of workout.

We offer everything from general gym memberships to classes, along with personalized coaching and nutrition guidance tailored to each person's goals and any past injuries. Our trainers take time to listen, design sessions around your needs, and patiently teach you how to use each piece of equipment.

We keep the gym clean and welcoming, and our community of friendly regulars makes it a comfortable place for newcomers and long-time members alike. Our flexible schedule works well for busy families and anyone with a changing routine, and rates are reasonable for the quality of coaching.
