I am currently doing mid volume polarized base which looks like this:
M: VO2 (60-90 Minutes)
T: Endurance (90-150 Minutes)
W: Rest (Sometimes a TrainNow Endurance workout)
R: Threshold (60-90 Minutes)
F: Endurance (90-150 Minutes)
I typically do these workouts in the evening after work (starting around 5-6 PM) but the WFH thread here has me considering adding second workouts to my day. For example a 60 minute TrainNow endurance workout or a low intensity Zwift ride during lunch. So I guess this boils down to several questions:
As long as I feel “good” does adding a second workout add more upside than downside?
If I do add a second workout should I just stick to adding z2 since I am doing Polarized? Could I add an additional high intensity workout on a day I am already scheduled to do an interval workout?
Splitting up endurance rides: I am not too familiar with the science but I am assuming doing, for example, a contiguous three hour z2 ride is more beneficial then say a one hour ride at lunch and a two hour ride in the evening. Both of these is still three hours of volume but I would assume the former is more conducive to adaptations?
If I am doing multiple z2 rides in a day is there a specific way I should split them?
