Josh is a high-performance specialist with over 20 years in Major League Baseball, including 12 seasons as Head Strength and Conditioning Coach for the Milwaukee Brewers. Integrating strength & conditioning with sports medicine, he played a key role in designing return-to-play systems and injury prevention strategies that consistently ranked among the lowest in MLB for total days lost to injury. As a member of the Brewers’ Sports Science Committee, Josh helped translate performance data into actionable training interventions, bridging the gap between rehabilitation and performance. He holds dual Master’s degrees in Sports Nutrition and Sports Medicine and specializes in modern resistance strategies, including flywheel training, to accelerate rehab and optimize return-to-play outcomes.

Having been part of Exerfly's journey from its early stages, Dejan has had the privilege of watching the company grow into what it is today. As the longest-serving member of the sales team, he has seen Exerfly's unique Motorized Flywheel Technology evolve from an exciting innovation into a trusted performance and rehabilitation solution used by elite sports organisations, commercial fitness facilities, physiotherapy clinics, and research institutions around the world. His role is centred around building relationships, understanding the unique needs of coaches, clinicians, and organisations, and helping them discover how Exerfly can make a genuine impact. Sport has always been a huge part of his life, with football being his greatest passion. He has always believed in staying active and continually finding better ways to train, and incorporating flywheel training into his own routine has completely changed the way he approaches strength, performance, and resilience. Being able to experience those benefits first-hand makes it even more rewarding to share Exerfly with others.
