Seiler’s 8-minute intervals (Polarized)

Often possible to push yourself hard on the final interval - that sense that you don’t need to leave anything in the tank.


what? I dont recover and then i can go even harder…?

i guess i should’ve add that first two didnt feel too hard

trial and error i guess

I wouldn’t worry too much. As with all workouts it’s not about nailing an individual workout perfectly, but about consistently completing it. Besides a few watts either way can just be because you had a decent night’s sleep.

So true! Trial and error. We’re only human and every day is a little different too. Good luck training!


As far as I can remember the guide was the maximum heart rate you got to in the final interval, he recommends not exceeding a percentage of max, was it 92%, haven’t read the article for quite a while now.
