But the easiest way to train yourself to put all your weight on the saddle is probably this:
That might be going a bit too far with the flat saddle concept. 
After having done some research on the forum I find that the simplest exercise (and easiest to understand) to reach this āfloating on the pedalā skill has been explained by scott ttocs Here
This must guarantee to only use the minimum needed torque to ride a unicycle.
I would hard boil it first, unless you like eggy pedals 
Scott actually admits that heās never tried that method himself!
Itās a good method for learning the āpedal floatingā concept. But as someone else wrote once on the forum (canāt quite remember who right now, must be all the Xmas wine getting at me), donāt forget that unicycling riding has different phases. And the gliding (once youāve reached your speed) comes after an acceleration phase, to go from still to cruise. During that phase, you will put more pressure on the pedals otherwise itāll take hours to reach the cruising speed. Not sure the eggs will love that phase. 
Last night there was one of those āParis by nightā unicycle group ride (this isnāt called like this indeed) that happens every Thuesday evening.
I used to participate to this weekly event with my 26er but havenāt done it that last 2 months (since I started to suffer from ITB) , so it was the occasion to test my 29er on this urban ride and especially to focus on the āflying on the pedalā stuff.
During nearly all the ride I focused on lifting my knees instead of pushing my legs downward and that was it !
Off course the leg that I āliftā is not lifting the pedal under the foot but it decreases A LOT the forces in conflict between my powerful quad (former bodybuilder) that is pushing the pedal downward and the other leg that is resisting to this strength in the crank that goes upward.
This makes the āimagine pedaling with eggs on the pedals tying not to break itā more easy to āfeelā, and fast pedaling seams to be easier too.
Some other muscles are involved in this āupwardā pedaling, like abs, and all the muscles that lift the upper part of legs, but it seams to considerably decrease the stress on the knees, tendons and muscles.
Riding in Paris streets (on the sidewalks) is sometime a little bit like doing a muni ride, it has nothing to do with linear road rides or bike paths rides, it is very variable, so after about 10-12 km of such a ride I should have felt the ITB pain much sooner.
I only felt it coming at the end when I was nearly arrived to my car, and this was a fist try, my technique still can improve much.
you are right Pierrox, the minimal pressure is not possible at the starting point, or when you have to slow very quick, but the cruising speed is attainable in few seconds, so I felt that I only pushed hard downward just after each free mount and during some technical bits of the way.
but during every moment I was focused on lifting my rising legs instead of pushing the downward pedal, the wheel seamed incredibly light.
In the end, when I was more tired, it was becoming hard to āliftā my knees and my āfloating on the pedalsā technique was not as good as in the beginning, and I felt the stress on my muscles and knee coming back.
I plan to test this kind of pedaling technique very soon on my 36er.
I wish I could reprogram my brain to pedal softly like that in an automatically way, and donāt see why it couldnāt happen.
Iāve been following this thread with interest, and Iām already starting to see results. Iāve never quite managed the āfloating on the pedalsā technique before, until I started reading how youāre progressing towards it, so thanks for that one!
Iāve found it easiest to practice it on a very slight decline - just let gravity make your wheel roll, and just let your feet get dragged along. Iāve also found it MUCH easier to practice this technique without using handlebars - maybe mine are too far forward, but when I use them I end up pushing too hard to keep myself upright, losing the smooth floating technique. I reckon Iāll be able to do it soon enough though, then nothing will stop me!
Youāre welcome, itās cool to read other riders progressing the same way 
I recently upgraded my handlebar with new bar-ends (that you can see in those PICS) and I tried to set it closer than before.
When I initially put kh handlebar both on my 29er and my 36er, I set it very much forward (at its maximum) and it was when I started to have this ITB syndrome issue.
Iām not saying it is due to this handlebar setting, (even though it could be) but itās clear than the more forward it is set, the more you are likely to lean forward and pedal fast (and hard if you are not focused on easy pedaling).
Since I set it closer, but more recently I set it even closer.
With closer handlebar, I was less likely to lean way forward and you are right, it was indeed better in order to focus on the easy pedaling work.
There is much difference between my light 29er and this heavy big wheel, even if the wheel is about 800gm lighter than when I bought it.
Not only the wheel and the whole 36er is louder but also I ride it with longer cranks (137 on the 36 vs 125 on the 29), so I donāt know exactly where does the different feeling come from, but itās just different (fore example I have to āliftā my knees higher).
To be more precise, it was a little bit harder to achieve this light pedaling skill maybe because of a fear factor and also because the wheel needs more power to rotate, so the effectively needed power on the down stroke is higher, so you need to remove more weight from the upstroke pedal and this + the cranks being longer, it takes more energy to lift your legs.
I guess I managed to make my pedal stoke lighter cause my ITB pain has been delayed, so I rode about 20km without much pain, I think the 17 first km were pain free.
Normally on the 36er I start to feel the pain after 10km, and when the wheel was heavier it was about 5km
I noticed that I had the choice between two āeasy pedalingā techniques:
-focusing on lifting the legs instead of pushing it downward.
-trying to lower the pressure feeling between the foot and the pedal during the whole 360 pedal stroke.
This last technique can be achieved by keeping just enough foot pressure not to slide from the pedal, but you can also just imagine having those virtual eggs under you feet.
What I did during this ride was just switching between the two techniques, the second one seamed more easy to practice on the 36er.
I tested out āfloat on the pedalsā yesterday. Iām on vacation and packed my 20" in the suitcase. Anyway, I was finishing up my session, and as a warm down, I practiced riding around trying to āfloatā on the pedals. What I noticed, is that my hips had compensate a lot, with a side to side motion, in order to maintain the lightness on the pedals.
Trying new things is great, because that is how we find / rediscover balance in certain parts of our body. I recall that, as a beginner, my regime of balance was a combination of weight-on-the-pedals and flailing-the-arms (extremities). Later on, I discovered the balance coming from the hips (core). Yesterday, I was able to rediscover that balance, by focusing on minimizing the weight on the pedals.
Agree 100%!!!
That thread and the one about Riding twisted should be compulsory riding for anyone willing to go from novice to advanced rider!
Yesterday night I had my first ever ride with no ITB pain at all since nearly 3 months ago.
14km of urban night ride on my 29er.
Is it due to my seat that I set low in a preventive purpose(seat->low pedal =81.5cm, Iām 5ā9) or are my daily special stretching + my lighter pedal stroke beginning to do the job?
I even didnāt wear my Zamst knee brace (special ITB).
Iāll have find the answer by doing slight adjustments on the seat height and see if the pain comes back when I put it higher.
I must admit than with such a low seat, itās a little bit hard for other parts of the knees since legs rise higher when the pedal is at the 12ā position so it puts more stress on the knees when I have to force because of the very variable floor reliefs during this ride on the sidewalks of Parisā¦
with such a low seat it also wasnāt so easy to āliftā my legs instead of pushing it but the ālow pressure under the feetā (or egg technique) worked well when I was focusing on it, which is still not a automatism so far.
Lets say that the more I ride, the more often I find myself remembering to pedal light and when it happens I instantly feel an enormous change: the unicycle immediately moves forward by itself, with nearly no energy needed.
When I do that I also instantly and automatically feel the seat under my crotch, so in my case itās rather light pedaling -> more weight on the seat than what is written on the title of this thread.
In other words the āmore body weight on the saddleā becomes a consequence of the easy pedaling rather than a cause.
