Recognized by Fitness Living Magazine™ For clear class organization, practical strength training, and a Redwood City community built around encouragement and belonging.
That belief sits at the center of ObstaCourse Fitness in Redwood City, California. Keith’s path moved through early weight training, boot camp coaching, obstacle course racing, Spartan-style training, and the hard process of building a gym from what once felt like an impossible idea. Today, the gym reflects the standard he kept returning to in his interview: community, strength, confidence, and core values.
“It’s a legacy. I put everything into this, and I wanted to have something that would carry on.”Keith Kern / Owner, ObstaCourse Fitness
A welcoming room, a smooth class flow, coaches who explain where to go, and a member culture where people do not feel judged or left alone. Keith described a gym where new members are paired with people who know the rhythm, where coaches watch form, and where the goal is to make someone feel, very quickly, “I belong here.”
The deeper impression is emotional as much as physical. Members are not only trying to lose weight, build muscle, or get through a workout. They are trying to feel stronger in daily life, carry more energy, build confidence, and replace the old internal story of “I can’t” with something more useful. At ObstaCourse Fitness, Keith wants the member experience to feel personal: seen, supported, rooted for, and never shamed.
Keith Kern has shaped ObstaCourse Fitness around a clear leadership standard: build strength, protect the class flow, coach people personally, and create a community where members feel important instead of anonymous.
Inside ObstaCourse Fitness
The fitness legacy Keith Kern has built at ObstaCourse Fitness is not only about workouts. It is about the kind of place a person walks into when they are tired of feeling weak, intimidated, bored, stuck, or unsure where to start. In Keith’s telling, the gym was born from a combination of personal training experience, obstacle course racing, boot camp coaching, financial pressure, persistence, and a belief that everyday people needed a stronger, more supportive training environment.
ObstaCourse Fitness is a strength and conditioning gym in Redwood City, California, led by Keith Kern. The gym combines large group strength and conditioning, small group strength training, personal training, obstacle course training, nutrition support, and accountability inside a community-centered environment where members are coached, welcomed, and encouraged to build strength, energy, confidence, and long-term capability.
Strength Training With Community at Its Core

Who the gym may suit and how to explore its current introductory offer.
A Gym Built From a Hard-Won Idea
Keith’s own introduction to fitness began early. As a teenager, he had a neighbor who was a bodybuilder, and that exposure gave him an affinity for lifting weights. He started with makeshift workouts at home, got his first local gym membership around age 14, and began to see training as something that could shape both the body and the person. Later, after working as an insurance agent and spending time in marketing, he found his way into boot camp-style fitness, coaching, and eventually obstacle course racing.
Before ObstaCourse Fitness opened, Keith had already spent years around training, marketing, coaching, and obstacle course racing. During his time in the boot camp world, he became a head coach and later managed multiple locations. He also captained a team of roughly 30 people for Rugged Maniac and continued into Spartan-style racing with members who wanted to keep challenging themselves.
That experience exposed a gap. Members wanted to race, but there was not a nearby place where Keith could properly teach obstacle technique. He imagined a gym that combined obstacle training with strength and conditioning for everyday people. Encouragement from a client, and support from people who believed in the idea, helped turn that ambition into a gym that opened in 2017.
The current website identifies Keith’s wife, Chrissy Kern, as co-owner and Candace Chan as co-founder. Their roles give the leadership story a broader frame, with shared responsibility for the community Keith described.
Community as the Core Difference
When Keith described what separates ObstaCourse Fitness, he returned again and again to community. Before opening the gym, he said he knew he needed to create one, but he did not yet fully understand how. Over time, he learned that the community had to be built around core values, not just shared workouts. That values-based culture became what he now calls the strongest part of the gym.
In his words, people come in and feel welcomed. They feel supported. They feel like they belong. They do not feel intimidated or shamed. For a fitness business that works with people who may have spent years telling themselves they are too old, too weak, too out of shape, or too far behind, that emotional safety is not a secondary feature. It is part of the result.
The Power of a Full-Body Training System
One of Keith’s clearest programming points is that large group training works best when members receive a well-rounded full-body routine. Many people cannot come every day at the exact right time for a highly split routine. For the everyday member training three or four times per week, Keith believes the workout needs to touch the whole body, rotate emphasis, and stay fresh enough that people who normally hate working out do not get bored.
That is why ObstaCourse Fitness does not rely on the same workout every day. Keith described a rotating style that keeps training new, fun, and challenging while still helping members build strength, conditioning, endurance, and confidence. The structure is practical: serious enough to produce progress, but approachable enough to help people stay consistent.
Seen, Supported, and Ready to Begin
A member at ObstaCourse Fitness is meant to feel welcomed, seen, coached, and included. Keith described a gym where people feel supported, rooted for, and important, with coaches who genuinely care about helping members do their best.
Strength and Conditioning for Everyday Life
Keith describes the ObstaCourse Fitness training philosophy as metabolic-style functional fitness. In practical terms, that means strength training blended with conditioning. It is not bodybuilding-specific training, and it is not cardio alone. It is designed for the everyday person who wants to function better, feel stronger, keep up with kids or grandkids, go on adventures, work around the house, and live with more physical independence.
That philosophy is especially visible in the gym’s large group strength and conditioning classes. Keith described classes that may include 15 to 40 people, with a major emphasis on flow. A class cannot feel chaotic. Stations need to make sense. Members need to know where to go. Coaches need to watch for form. Newer members need to be guided rather than left to figure things out on their own.
ObstaCourse Fitness matters because Keith Kern has made the emotional side of fitness part of the training standard: members are coached to get stronger, but also to feel capable enough to keep showing up.

“I'm so happy I found this gym. Great workouts, really great coaches, and an awesome community. The workouts are fun and challenging! They also teach you about nutrition and how to eat in order to reach your goals.”
Progress Members Can Feel in Real Life
Asked what he hopes members experience, Keith began with strength. He described members noticing heavier lifts, more energy, and greater confidence as they practice consistently. These are the changes he values in his coaching, rather than a fixed timeline or a promised outcome for every member.
For Keith, strength is not limited to the gym floor. Physical strength carries into daily life. Members have more energy, better endurance, and more independence. Mentally, he said, people can become more focused, happier, more confident, and more productive. One of the member stories that stayed with him involved someone who went from hating exercise and feeling unhappy with himself to becoming stronger, more confident, more productive at work, and better in his roles as a leader, husband, and father.
Why This Matters Locally
In Redwood City, a gym has to earn attention through more than a class schedule. Keith said new members find ObstaCourse Fitness through social media, Google, referrals, word of mouth, paid marketing, and research across the web. But the deeper question is what people feel once they arrive. In his view, the gym should make someone think, “This is the place I want to be at.”
For people searching for a Redwood City strength and conditioning gym, a functional fitness gym, a supportive group fitness program, or obstacle course training near them, ObstaCourse Fitness offers a distinct local identity. It is not built only around intensity. It is built around making strength feel possible, making the class experience flow, and making members feel that they are part of a community that wants them to win.
