There is a danger that one can have tendon inflammation if it is too extreme. I'd probably start with looking at my seat height. Personally, I like the exercise of unclipping, while the bike is in the trainer, and putting my heel on the pedal. If I can't pedal backwards without rocking my hips, I've likely got the seat too high. As it turns out, I’ve spent years dealing with occasional flare ups of the tendons on the right leg. Once I got the seat down a few mm, that all went away. In any event, once I had my seat height adjusted correctly, a pedal stroke with less "toe down" was easy to maintain.
