I’m not sure if this is a joke or not so I wanted to clarify. IF can’t be used to gauge training zone.
For example this is a VO2 Max workout that has an IF between .82 → .9
It was indeed meant to be a joke … I fall into the trap of trying to be funny on the internet and failing over and over again.
It was more meant like: Be happy of “just” being “accused” of too much sweetspot when you bring up an example which contains 4x intensity (3xVo2max and 1x ss) and 1 easy ride on a 5day plan.
And the SS day has a Z2 alternative available 
.
So basically 0 Sweet spot at all in that plan if you choose…but we’re “just” sweet spot. 
I used TrainNow for the first day and it was SPOT ON with the intensity and duration. Well, I picked the duration. In the last 2 years I have never been able to complete the Sweet Spot workout “Phoenix +2” I always fail somewhere between 43-51 minutes. Once again, my Build cycle had it on my training plan for today. Instead, I used TrainNow and was suggested “Carson +2” which is very similar to Phoenix except that it breaks up the 90 minutes with 2 minutes rests. And whatddya know? A challenging, sweaty, hard workout that I actually completed. And that’s just from the first TrainnNow that I’ve picked. Can’t wait to see how predictive it continues to be,
Woohooo!

Hope that @brendanhousler doesn’t mind me posting this here? I thought it was very interesting.
I had a very similar experience. I really struggle with VO2max workouts (I know that’s the point, but I mean I struggle to complete them on plan at full intensity). In my rest week now, but as I flunked last week’s VO2max workout so badly, I decided to do one. I chose Ansel Adams, but TrainNow suggested Thimble - much easier. I went with the recommendation and it was just doable, so I think it got my ability spot on.
No to all that. Who would want that when you’ve got TR?
I had Ansel Adems +4 on my build block today but knowing I was not keeping up with the past couple weeks of workouts at this intensity, I swapped to Thimble +2 after seeing your comment. I can confidently say that it was a challenging workout, but if I had kept the original prescription, I would 100% not have even finished all the intervals.
don’t mind at all; Cody was great, so knowledgeable. I will post my own person thoughts on the YouTube channel hopefully later this week or next week. Good luck with your training @PusherMan !!
