What W/kg do I need for club rides?

That depends on the pace, terrain, and how the group rides. W/kg helps on climbs, but pack riding and drafting still matter a lot on flats.

Which zone model should I use?

Use the model that matches your coach, training platform, or team setup. Consistency matters more than the number of zones itself.

Do zones change when my FTP changes?

Yes. If FTP moves, zone boundaries should move with it so the training language stays aligned with your current capacity.

How do I know if wkg and power zones is the main lever to change?

If a small change produces a clear, repeatable difference in how the ride feels or performs, wkg and power zones is probably a useful lever. If not, move to the next variable rather than making a bigger guess.

When should I get a coach, fitter, or clinician involved?

Get help when the issue keeps returning, when more than one system is involved, or when the symptoms are sharp, persistent, or happening outside normal riding.
