How do people approximately calculate their LT1 and LT 2 without a blood test?

[image] DarthShivious: It might be great to do the LT1 stuff on trainer, but too boring. Got a CTS email in my inbox last week on The Role of Zone 2 Training During Indoor Cycling - worth a quick read IMHO.

I estimated LT1 at 210w from my ramp test a few posts up. Xert has it at 213w, with an FTP of 270w.

Really depends on what his goals are. Lots of ways to go after raising VO2max - aerobic build into FTP work, high power lactate clearance/tolerance, anaerobic work. Just depends on what the athlete wants/needs.

redlude97: Anyone with LT1 and Xert LTP data to compare? I know that theres a few coaches starting to measure those over on Xert The thing I’m finding more and more about this stuff, and even FTP, etc., is using the data to inform “feel”. HR and power (to a lesser extent) will change with a …

Yep, I just didn’t see what his goals were, so it’s tough to answer. :slightly_smiling_face:

redlude97: especially with “stuff” thrown in like a lot of the pros are doing is making endurance training enjoyable. I can’t tell you how excited I am to be freeing up time to increase my Z2 time. I’ve seen great gains the last year by adding Z2 time to interval workouts, but I’m typically …

[image] kurt.braeckel: Yep, I just didn’t see what his goals were, so it’s tough to answer. :slightly_smiling_face: My only goal at present is to be reasonably fit and have fun riding when the weather turns. To be “reasonably fit” the way I think of things, will require a couple blocks of ac…

[image] DarthShivious: It was the comment above that had me thinking about what to do after an LT1 block stopped giving improvements. Here. is my perspective: I don’t do lactate testing so for me its “zone2” work (power if good zones, otherwise HR) all year round there is a foundation of 4-…
