On November 21 and 22, 2025, around 300 invited guests came together in the Donauhallen Donaueschingen to experience an event that would quickly prove to be a milestone for the future of muscle length training. The focus was on the first public presentation of the completely newly developed five next equipment series - a system that combines modern sensor technology, biomechanical precision and a consistently user-centered training concept.
The mix of inspiring presentations, practical training sessions and the vision of a new training dimension ensured that the event is already considered one of the highlights of 2025. Industry experts are already describing five next as an "insider tip" for FIBO 2026 and a potential game changer that is likely to have a lasting impact on the mobility and muscle length sector.
Strong start with moving impulses
milongroup Managing Director and five co-founder Wolf Harwath opened the event and welcomed Wolfgang Packi and Boris Grundl, two personalities who have been providing significant impetus for the health and training industry for years.
Packi impressively reminded the audience that sustainable pain therapy always begins where movement patterns and muscle chains become functional again. With emotional video sequences, he paid tribute to the pioneering work of his father Walter Packi, whose visions have made a significant contribution to mobility and muscle length training becoming standard in many health centers today.
Afterwards, mentor, speaker and bestselling author Boris Grundl gave the audience goosebumps with his keynote speech "A desire for responsibility", which drew applause lasting several minutes.
The premiere: five next takes muscle length training to a new level
A highlight of the first day of the event was the official unveiling of the five next product generation. Wolf Harwath and co-founder Christoph Limberger, who as technical director played a key role in the development of the new series, presented the devices to a professional audience for the first time.
The new series combines
state-of-the-art sensor technology,
digital training guidance,
precise movement analysis,
an ergonomically revised device concept and
AI-supported data tracking (optionally in the cloud).
five next has not only been visually rethought, the training logic has also been consistently geared towards user experience, precision and results orientation.
Day 2: Practice deepens theory - focus on muscle length
On the second day, five specialists Marco Montanez, Peter Hinojal and Nikolas "Kiri" Kirilow took the helm at the five location in Hüfingen and explained how muscle length training can be integrated into training and therapy in a meaningful way. The participants were given methods that can be implemented directly, were able to experience movement sequences for themselves and try out the new features of the series straight away.
The audience was particularly impressed by the intuitive usability: the devices guide users visibly, tangibly and comprehensibly through each position - a major step forward for healthcare facilities that focus on quality, safety and measurable results.
five next: data that motivates - results that impress
With the new sensor technology, users experience training that provides immediate feedback: "Feel it, measure it, do it - no excuses." Every movement is analyzed, documented and clearly presented. This combination of real-time feedback and clearly visualized training data ensures maximum transparency for both exercisers and therapists.
five next sees itself as the third training pillar, muscle length, alongside strength and endurance. An area that is increasingly recognized as a decisive factor for performance, health and freedom from pain.
Guest comments on the event
"An all-round successful event with top speakers."
"It was fantastic."
"The presentations were great, Wolfgang Packi really impressed me."
"I found Boris Grundl's presentation very enriching."
Guest feedback on the new five next generation
"The new equipment that five has built is mega. Mobility training on a completely new level. Great work, respect!"
"Exactly what will help customers to train more effectively."
"If we had another club, we would have ordered immediately."
"The best step five could have taken."
Classification and outlook: Why 2025 is a turning point
The "five fascinates 2025" event impressively illustrated where muscle length training is heading: towards intelligent, digital and scientifically based training systems. The increasing demand for mobility, pain reduction and everyday performance makes this approach more relevant than ever - for fitness facilities, physiotherapy practices, rehabilitation centers and ambitious sports clubs alike.
Anyone who wants to experience what the future of flexibility and mobility feels like should mark FIBO 2026 firmly in their calendar: That's where five next will be presented to the general public for the first time.
