The Karnage Havok HIIT Bundle combines three of the most powerful conditioning tools in elite functional training into one unmatched performance package:
✔ Havok Curved Treadmill
✔ Havok Reaper Air Bike
✔ Havok HIIT SkiErg & Platform
This trio delivers total-body conditioning, explosive power, endurance development, and metabolic dominance—making it the perfect solution for Cross Training gyms, performance centres, HYROX-style facilities, PT studios, and elite home setups.
The curved treadmill delivers self-powered sprinting and sled-style resistance for leg strength, speed, and calorie burn. The air bike attacks both the upper and lower body with relentless intensity. The SkiErg completes the system with low-impact, high-output pulling power that develops the posterior chain, core, and lungs.
Together, they create the perfect HIIT ecosystem—allowing athletes to move seamlessly between running, riding, and pulling with no compromise in intensity, realism, or training stimulus. Whether programmed for circuits, intervals, endurance blocks, or competitions, the Havok HIIT Bundle delivers brutal efficiency and limitless variety.
