On 100% Max Resistance

When I teach I like to guide the class using "% max resistance" for the simple reason that "100% max resistance" is a relative number that is the same for everyone - because it's relative! That is: while 100% max resistance is the same for everyone the absolute amount of resistance applied to each person's wheel will differ!!

So...what exactly IS 100% max resistance?
I define 100% M.R. as the absolute maximum amount of resistance you can apply to the wheel while still pedaling in a smooth, round pedal stroke at 60 RPM!

Once you have a handle on your 100% M.R. everything else becomes relatively easy to comprehend....
  • A hill starts around 50% of your M.R.
  • The amount of resistance required to juuust counter-balance your weight in the jog position is 35% M.R.
  • Flat roads will have anywhere from 20% to 50% M.R., while one's cadence will be no lower than "your favorite happy pedaling speed" (or 80 RPM, whichever is lower).
How do I find my "100% M.R."?
Well, first warm up well and then once warm set your leg speed to 60 RPM. Now start adding resistance a little at a time all the way until you can just baaaaarely hold that 60RPM. That amount of resistance is ~100% M.R. Remember that feeling in your legs and work all other amounts of resistance relative to the feeling of 100% M.R.
Oh, and don't forget that 100% M.R. is going differ in absolute resistance on the wheel depending on whether you're seated or standing. That is, if you're at 100% M.R. you could still stand up and add more resistance! I usually estimate that there is a 10% difference in % resistance between the seated position and standing position.

Remember, if you ever hold back on the resistance the only person you're cheating is yourself ;-)

Keep those wheels spinning smoothly.
