I am doing the 40+ plus MTB base program. When I do zwift workouts, should I be following power zones or HR zones. My heart rate typically has me one zone above my power zone based on FTP.Thanks!

Indoors HR is often higher due to being warmer.Coach LyndaAuthorPostsViewing 1 reply threadYou must be logged in to reply to this topic.Log In Username: Password: Keep me signed in Log In
