Well, at least for mounting tires, you can make it easy by using one of these:

today i rode 35 miles on the mr pink and set 8 PRs....on segments i've been riding for years. the only thing i can figure is that riding these heavy ass bikes that i've been on the last 3yrs somehow conditioned me and now this 25lb road bike feels like way less and seemingly hauls ass.
So you are cheating then.

In the age of featherweight carbon bikes, riding a 25 lb road bike is pretty hardcore.
We used to fill our water bottles with sand and rocks for training rides.

the mr pink is far from light, but still ~15lbs lighter than the riv and other bikes i've been on the past few years. weighs more than the nature boy, but the gears make up for it.

If a heavy bike makes you want to push harder, then I can see how it's a good motivation tool, however.

I've always hated swapping tires. Until now.
The Clement's on my nature boy come off and go on so easy I'm looking for excuses to take them off. Just like my pants.
I loled.
Sh–––t.

I've never understood this. How does riding a heavy bike make you stronger? IME it's how hard pedal that makes you strong, less the bike. Your effort is independent of the machine you're on.
If a heavy bike makes you want to push harder, then I can see how it's a good motivation tool, however.

Saying that effort is independent of the weight of the bike is like telling a weight lifter that his effort is independent of the amount of weight being lifted.
Pushing a heavier bike up a hill is no different from pushing a heavier stack of weights in the weight room. It takes more effort to move a heavier weight.
Another way to look at it is work. Moving more mass requires more work. Someone who rode a 30 lb bike up a hill did more work than someone who rode a 20 lb bike up the same hill.

However many w/kg is going to be the same no matter the bike, so bike weight doesn't really matter for training.

Today I learned that a tennis ball and a wall make for a damn satisfying self-massage on the back muscles.

But before then it was heart rate, and perceived exertion before that.
The weight lifting analogy doesn't work because bicycles have gears and with sufficiently low gears you can get a huge bike up a hill without too much power - or work / time.

Power is an instantaneous measurement. Work is measured over time.
At the risk of sounding condescending, what I'm talking about is basic physics. It is middle school curricula.

This is not true because a lower gear will cause the duration to increase. It will simply take you longer.

Work = Force x Distance
Power = Work / time. Power is not an instantaneous measurement, and time is the missing variable in the weight lifting analogy.
Pushing a bike up a hill is work. Doing it faster (in less time) requires more power. The point I've been trying to make is that your body doesn't know the difference between bikes - just how hard you are working.
EDIT: It might be easier to think about this in terms of heart rate - another metric of aerobic expenditure that is directly proportional to power, with some drift of course. If you rode at ~180 bpm for 5 minutes, do you think it would make a difference to your cardiovascular system what bike you were on?

Unfortunately for me, the cutoff age to become a Trappist monk is 50.
