Base training is basetraining. Its improves your fitness alot, and is laying the foundation to upcoming gains. You have “practiced” longer intervals for some time now, and your Heart doesnt require so much blood as before, because your fitness is improving - so your heart dont stress as much as before. I am in the same bout here, i can do FTP interval sets, where i am in the zone 3 - but i know, if I bump up the intensity, i wont last the whole session.
Ill leave it . unless your legs is not screaming - Lets the legs decide, not the heartrate.
It’s likely that you are fitter because you have increased fatigue resistance, especially since you’re noticing this after SSB volume 1 (a phase that focuses on “extensive” type workouts). SSB volume 2 will actually do less pure sweet spot work in favor of more “intensive” workouts (threshold, VO2max). That block, and subsequently a Build phase are when you would expect to see FTP increases, if you complete the work and life doesn’t get in the way. Granted, some folks report FTP increases after Vol 1, but it’s not really what that phase is designed to do.
Also, I would not mess with the intensity like you’ve been doing, especially based on HR. Volume 2 will break you of that habit. It’s hard.
My tacx vortex came and i made the first spin the ramp test since I need to have a baseline of how it performs.
My ftp came out as 230 which was almost a 7% increase from less than a week back. I suspect if I had enough rest and harden up at the last few minutes, it would have been even more.
Probably will increase the intensity for the next workout and see how it goes.
All in all,I’m quite happy my training reap rewards.
Use the FTP of 230 from the test, at least for a week or so. It is a better option than just bumping the intensity based on what you think you should have got.
If you feel it is significantly out then wait a day and take the test again before starting the next phase of the plan
