I think this is due to two things:
- Theyβre trying to keep it as close to Seilerβs literature and what heβs said as possible, so they kept it as close to 80/20 as they could. Seiler also prescribes the 4/8/16 interval structure, as well.
- The efficacy of a 4 hour/week Polarized plan remains to be seen. I would think that little time on the bike is below the floor of effectiveness for such a plan, and I donβt appear to be alone if you check out the feedback thread Nate made prior to the launch. Below is a link to Nateβs post, which also notes the oddity of a LV Polarized plan.
