ASSAULT BIKE

The Assault AirBike is widely regarded as the single most brutal conditioning tool in any gym — and Spark Fitness Zone has it in the functional training zone for a reason. Unlike magnetic or friction resistance bikes, the Assault Bike uses a large fan to generate resistance: the harder you pedal and push, the more air resistance the fan creates.

This means resistance is completely unlimited and self-regulating — every member from beginner to elite athlete trains at their own ceiling. The dual-arm handles engage the upper body simultaneously with the legs, recruiting an estimated 80%+ of skeletal muscle mass in a single movement. This produces the highest metabolic output — calories per minute and VO2 max stimulus — of almost any single piece of cardio equipment.

It is used extensively in CrossFit, military fitness, NFL conditioning, and cardiac rehab for exactly this reason. At Spark Fitness Zone, the Assault Bike is a key tool in both the fat loss programme (20-second Tabata intervals with 10-second rest) and the athletic performance conditioning work. The LCD console tracks calories, RPM, heart rate, and watts in real time.

Because it requires zero electricity for the resistance mechanism, it never breaks down mid-session. An essential machine for anyone serious about metabolic conditioning.
