Dynamic boxing training in a modern gym: a group of motivated athletes in action ( (C) )
Nuremberg, December 20, 2025 – According to current market analyses, interest in fitness boxing and martial arts-based workouts has increased by over 180% since 2023. Boxing is now considered the ultimate “fitness revolution” because it combines peak physical performance with mental stress relief. But in practice, many trainees fail because of the technology – not the athletic aspect, but the digital one.
Science proves: The quality of the intervals is decisive The secret behind the success of boxing training is high-intensity interval training (HIIT). Science magazines such as Quarks confirm that HIIT not only burns 25-30% more calories than moderate training, but is also a real booster for the cardiovascular system. The decisive factor here is “anaerobic capacity” – the body’s ability to work under maximum stress. This can only be optimally trained if the stress and recovery phases are adhered to. Smartphone frustration in the boxing gym In theory, fitness apps sound practical, but in the practice of a boxing gym, they are often out of place:
Usability: A touchscreen is impossible to use with bandaged hands or boxing gloves. Acoustics: In a room where punches are landing on sandbags and music is playing, cell phone speakers are simply drowned out. Focus: Every notification on the display interrupts the “flow” and destroys the mental toughness that defines boxing.
The “sacred bell”: KondiMaster as conductor Professional gyms and ambitious home athletes are once again turning to dedicated legacy training equipment instead of app solutions. KondiMaster’s interval timers have been specially developed for these harsh environments. “A trainer needs to be able to focus on their prot?g?’s posture, not on an app,” explains Stefan Burger from KondiMaster.
With a volume of approx. 95 dB, the signal cuts through any noise level and replaces the classic ring bell. As a stationary device, the timer becomes an integral part of the equipment – indestructible, loud, and absolutely reliable. The integrated programs for classic lap times or individual HIIT intervals allow you to concentrate fully on the next hook.
If you want to train like a champion in 2026, you don’t need a smartphone on your punching bag, but a tool that sets the pace – unyielding and precise.
With the new KondiMaster FLEX Timer, KondiMaster responds directly to practical use in the gym. Particularly popular intervals such as 40/10 (classic for intensive HIIT & MMA drills) or 50/10 (ideal for hard training phases with minimal breaks) can be set to specific positions. This means that the operation remains familiar, while the timer accurately reflects the training logic of modern workouts – loud, robust, smartphone-free, and consistently designed for precise intervals.
