With a sprint duration that’s higher than REHIT Intense (120 vs. 40 seconds) this is one of CAROL Bike’s tougher workouts.
Here’s how it works:
- Short warm up
- 30x4-second sprints, with up to 30-second recovery between each sprint
- Final 3-minute cooldown
Sprints demand maximum intensity, while warm-up, recovery and cooldown are performed at very low intensity.
The workout lasts 10—22 minutes.
