the nonlinearity of force is very counterintuitive it is not obvious why for example being on a bike even if you are riding at a very high level of power so remember on a bike your leg is going around at 90 times per minute so even if you did a one minute all out that's 90 reps or call it 45 reps that's nothing compared to when you're doing an allout set for 10 reps in the gym it's such a difference in force
