HIIT is often associated with some form of “4-minute fat burner” workout, which IS NOT what I am talking about.

HIIT workouts consist of repeated bouts of high-intensity work performed above the lactate threshold (a perceived effort of “hard” or greater) or critical speed/power, interspersed by periods of low-intensity exercise or complete rest.

HIIT has the benefit of adding speed to your training without adding much fatigue when compared to traditional interval training.

Research shows that completing a workout of 3x {13x 30sec ‘fast’ - 15 sec ‘easy’} can increase your workout time above VO2max by an average of 54% when compared to traditional long intervals (4 x 5 min work-intervals, 2.5min rest) (Almquist NW, 2020).
