It’s a commonly-asked question. They’re not hard workouts and they’re not supposed to be hard.

Sustained efforts vs vo2 max and heart rate

Bluebell has caught out others before expecting it to be hard… It needs a disclaimer! Remember to always check the IF of the workout*, not just the intensity of the intervals, to get a true picture of the difficulty. *Be careful when workouts have a long period of endurance pinned on the end as this can bring down the overall IF.

Tuesdays will get tough soon, promise.
