Sounds like a good breakdown, although I’m not sure what mobility involves. Yoga, Tai Chi, Core? I’ve been remiss in not doing core and upper body but am changing that. I think endurance or polarized plans make the most sense for 60+ if our goal is health and longevity, over a constant reach to “improve.” I’m finishing a recovery/endurance week, which has felt great. If I’m not doing a TR workout, I tend to push myself at times where my normalized power is close to my FTP.
As far as recommenations to balance the components, I don’t have easy answers. Earlier in this thread @Nate_Pearson teased out that TR had (and still has) something in the works for masters and above cyclists, but the adaptive training obviously is taking priority.
A broader comment for 60+, I have not yet seen comments here or in the AT thread (Adaptive Training Closed Beta Update) from “old guys” who are in the current closed beta (4,000 subscribers so far.) If I understand AT, it should help with the balance issue.
