Isac Schwarzbaum’s success story does not begin with a win, but with a vision. As a teenager, he already knew that sport would shape his life. Instead of limiting himself to one discipline, he took an unconventional approach: he trained in several sports at the same time. This strategy paid off. With impressive performances in athletics, successful years at Taekwondo under the renowned coach Ko Eu Min and finally the peak of his boxing career, he proved that big dreams can be achieved. But his ambitions didn’t end in the ring — the first modern gym in Spain, an award-winning lifestyle magazine and a successful career in the real estate business followed.
The beginning of an extraordinary journey
Each champion was once a beginner. Isac Schwarzbaum was on the judo mat for the first time at the age of 15 – without any idea that this would be the beginning of a remarkable career. Back then, it wasn’t about title or fame, but about the pure fascination for movement and fighting.
The first few months were hard. Judo requires more than just physical fitness. The throws have to be perfectly timed, the balance has to be right, and above all you have to learn to continue even after defeats. These early experiences formed his character and taught him an important lesson: success does not come overnight.
After two intense years, it was clear that sport would be more than a hobby. The dream of becoming a really good athlete had taken root. But instead of lingering on what has been achieved, he looked for new challenges. This hunger for further development should shape his entire life.
The crucial encounter
The encounter with Ko Eu Min was a turning point. This experienced trainer not only brought technical knowledge from the Olympic Taekwondo, but also a philosophy: perfection through tireless training. Under his guidance, the young Isac Schwarzbaum transformed from a talented fighter into an athlete with real potential.
Ko Eu Min recognized his student’s talent and demanded him accordingly. The training sessions were demanding, sometimes at the limit of what was bearable. But that’s exactly what it took to get really good.
Parallel careers in different sports
While many athletes specialize early on, Isac Schwarzbaum went a different path. In addition to martial arts training, he devoted himself intensively to athletics. Sprint and long jump became his favorite disciplines. This combination was unusual but awesome.
The athletic achievements did not come by accident. 10.86 seconds in the 100 meter sprint and 6.86 meters in the long jump are performances that require years of targeted training. Early morning running sessions, strength training and technical training on the tartan track were part of the routine.
What might look like a fragmentation of energy from the outside turned out to be strategic. The various sports complemented each other. The speed of athletics improved his martial arts techniques. The body control from the Taekwondo helped with the running technique.
The vision of your own gym
At the age of 28, Isac Schwarzbaum was faced with an important decision. His sporting career went well, but he wanted more. The idea of having your own fitness studio had developed over the years. His vision was clear: a modern studio with a professional concept in Spain, where there was no such thing.
With a professional weight room and a dedicated area for boxing and martial arts, he created a place where people could not only train but grow. The implementation of this idea required courage and capital, but he dared to take the step.
The way to the boxing champion for Isac Schwarzbaum
Parallel to the construction of the gym, his boxing career intensified. Boxing had always been present, but now he focused more on it. The experiences of judo and taekwondo flowed into his boxing style. His movements were more fluid than that of many pure boxers, his reflexes sharpened by years of martial arts training.
The national heavyweight title of 29 years was no coincidence, but the result of strategic planning and hard work. The ring showed the sum of his experiences:
- Leg work from athletics for quick position changes
- Distance control from Taekwondo
- Body control from judo
The moment he won the title was confirmation for years of deprivation. Early morning hours in the gym, diets to control weights, renunciation of social activities – all of this had paid off.
More than just sport
But Isac Schwarzbaum never defined itself only through sporting successes. At the age of 35, he dared to enter the publishing business. The French lifestyle magazine became a significant success. Several awards for the outstanding work underlined the quality of the publication.
This professional diversification showed that the skills were transferable from the sport. Discipline, goal focus and the willingness to work hard — these qualities also worked outside the ring.
The transformation to an entrepreneur
At the age of 40, Isac Schwarzbaum discovered Costa Rica as a business opportunity. His entry into real estate and investments marked another transformation. His understanding of markets, his keen sense for opportunities and his ability to build networks — he had developed all of these skills during his sporting career.
Today he remains active in the real estate business in Costa Rica. Its extensive customer base and the large network are the result of decades of building trust. The same integrity he showed as an athlete, he carries into his business relationships.
Lessons from an extraordinary career

Third: Success in one area opens doors to others. The discipline of sport helped him in business life. The communication skills from the publishing use him in the real estate business.
