The Self Defense Club is located in Blankenfelde-Mahlow, a town just south of Berlin. It is run by Marcus, who built the club alongside his full-time job as a soldier. For over eight years, he has been teaching self-defence, Krav Maga, MMA and boxing with a clear focus: a welcoming atmosphere rather than competitive pressure.
The studio attracts a surprisingly broad audience. In addition to adults, many children and teenagers train in age-appropriate groups. There is also a dedicated Ladies Class to help women get started more comfortably.
Marcus initially managed everything manually, until the pandemic made attendance documentation mandatory.
"It just took time away from training. I knew I needed a system where people could book themselves in."
After a short period using Fitogram, he quickly ran into limitations: lack of flexibility, no further development and no support. It soon became clear that he needed a new solution. This search ultimately led him to bsport.
“I wanted more flexibility, like when creating classes or choosing payment options. At some point, I simply hit a wall.”
Efficiency is everything for Marcus, who runs the Self Defence Club alongside his full-time job. bsport helps him keep core tasks streamlined and reliable.
Marcus saves the most time when it comes to managing memberships. New clients choose the membership that suits them, sign up online and are ready to go within minutes.
Bookings are also handled entirely through the app. Members register themselves for sessions, view the training schedule and easily find classes that match their needs.
“Clients can independently select and complete their membership. That takes the task off my plate.”
Every minute counts in a busy studio. That’s why it is crucial that last-minute updates, such as trainer substitutions, run smoothly. If Marcus cannot teach a class himself, he simply selects a replacement and activates the notification setting. All attendees are automatically informed. For him, this is not just convenient but essential to keep things running professionally and without extra work.
The automated trial booking process makes it easy for newcomers to sign up and get started right away. With just a few clicks, they can register, create their account and book their first session. This smoother experience has significantly improved conversions and helped grow the studio’s membership.
Marcus has a clear vision for the future: "My goal is to offer more training slots and keep improving the quality of our classes."
To achieve this, he regularly invests in advanced training for himself and his coaches, and relies on digital tools to support his growth.
bsport plays an active role in helping him move forward. Many processes have already been simplified, allowing him to focus on what matters most: delivering great training.
“With bsport, we are really on the right track: things are running smoothly and the focus is finally back on the training itself.”
