REHIT Intermediate: 3x15-second sprints

Presumed to deliver similar fitness benefits as REHIT Intense but in a lighter workout.
With 3×15-second max-intensity sprints, and low-intensity warm-up and cooldown, REHIT Intermediate works like this:

  • Warm up: 20-seconds to 2-minute 
  • Sprint 1: 15-seconds 
  • Recovery: 1-minute to 3-minutes 
  • Sprint 2: 15-seconds 
  • Recovery: 1-minute to 3-minutes 
  • Sprint 3: 15-seconds 
  • Cooldown: 3-minutes 


Despite having a larger overall sprint volume than REHIT Intense (45 vs 40 seconds) and eliciting a similar physiological stress (peak heart rate), and therefore also presumed training stimulus, the 3×15-second REHIT Intermediate workout might be a great choice for you if 2×20-second sprints feel too tough and 2×15-second sprints not challenging enough. 


The duration of this REHIT Intermediate workout is 6:05 – 10:45 minutes, depending on the length of your warm up and recovery.
