Change bike fit to reduce amount I "lift up" on my pedals It's folklore than a benefit of clipless pedals is that you can generate power while pulling your foot &quot;up&quot; as well as pushing it &quot;down&quot;. I've noticed that under very particular circumstances (while on an indoor trainer, in non-ERG mode, on a climb) that I've started having slight pain which is easiest explained by this point.
Note that this pain has only shown up in these circumstances (which I can easily avoid) and I've always stopped immediately when I noticed it (and it did not linger after that). This is to say that this is a rather minor medical issue, so I'm unlikely to schedule an appointment over it during the pandemic. This means that my options are either:

Try to fix it myself (likely via adjusting bike fit)
Only ride outside/in ERG mode during the pandemic

Either one of these seems fine, I just thought I'd ask for advice about the first before jumping to the second.
In particular, I've been having some pain (roughly) in this region of my left foot:

People other places online say that this part of your foot is responsible for lifting up your toes. I suspect that poor bike fit (and poor pedaling form) is causing me to try to do precisely this. Are there modifications that I could make to my bike to make this movement less likely/&quot;encouraged&quot;?
I would suggest that changing your bike fit to optimise the mechanics of riding a turbo trainer is somewhat cart-before-horse.
However to take it seriously for a moment, if you want the best possible bike fit for pulling up on the pedals on your trainer when the resistance goes up, this will probably involve substantially changing the current relationship between hip/shin/ankle etc. E.g. putting the upstroke of your pedal cycle where the downstroke currently is might do the trick. This may have... consequences for other, perhaps slightly higher priority, aspects of cycling.
I would not describe your issue as originating from poor bike fit or poor pedalling form. I would say it originates from doing something that you would never normally do in the course of riding a bike, and so that the solution is to... not do it (i.e., your option 2)
