It also rises the more tired you get. I did 9 2 minute vo2 max intervals at >110 revs last night. My max hr is 178′ my first interval topped out at 162 and the last 173. If you look at the HR profile the general trend is it get higher the longer the workout goes on.
It was Mills, jeez did it hurt. I couldn’t complete them all losing about 20 secs of cadence or changing down a gear at then end of the interval of but according to the on screen instructions this is perfect as long as the initial 45secs/1min at v02 max is achieved. I completed the 9th by gritting my teeth and imagining I was winning a crit, but felt very sick and unsteady for about a minute after.
Fwiw, after 8 months of TR I think I’ve reached a point where my Ftp gains will be much more marginal than in the past.
Does anyone else do there workouts on an incline based resistance with a view to improving power quickly? 😈
