Any thoughts on this one? Whenever I’m doing FTP-type intervals (8 minutes to 1 hr.), it always seems like the first 3 minutes of the interval is the worst. More accurately, the first 45 seconds are almost easy (I assume because creatine phosphate is being used to fuel the effort), but from 45 seconds to 3 minutes the interval is always the hardest. After 3 minutes, though, I seem to get into a “groove” and I can usually keep going almost indefinitely (up to an hour) at that effort. In that context, I thought that it might make sense to do 3 minute ftp repeats, with a very short rest interval (probably @ 50% ftp to maximize lactate clearing) of around 30 sec. to 1 min. (to allow for rebuffering of creatine phosphate?) and then go again with the 3 minute ftp interval - essentially until exhaustion. The aim of the workout would be to train that first 3 minutes, because, I assume there is something important happening during that time based on my subjective feelings.
For reference, I’m 54 yrs. old. 1 hr. FTP is 256 watts. Weight is approx. 62kg. WKO5 says my VO2Max is 64 @ 324 watts (I’ve been as high as 73 @355watts).
