Every time somebody talks about picking up an ST from a tip over somebody else posts the video of a woman righting a GW or a 12you girl doing the same as though it's an apples to apples comparison. It's not. It's more like oranges to guavas.
If an ST and GW were both leaned over to their respective TOBs I bet the ST would be lower (closer to the ground) and therefore require more effort to right than from the same angle as the GW. I also believe the weight distribution of the GW compared to an ST also contributes to an easier chore.
There's no getting around the physics. Whether righting an ST or putting it on the center stand, physical strength is needed and it's the same amount for everyone if the bike's weight is a constant. IRL that weight varies so the effort required varies as well.
Traditionally a bike is raised or lifted onto the stand then rolled back slightly to lock it in place. As pointed out the raising/lifting is done with the leg and not the arm. It's no mystery. Increase the distant between the center stand tang/lever and the hand hold (or any other purchase point) sufficiently and the bike can be rocked back to the resting position. With enough enthusiasm it "parks" itself no rocking required.
There are those who's weight on the center stand tang/lever alone is sufficient enough to pop the bike up and into position with a hand on the upper handle unnecessary. That's not me.
I'm sure the minimal required effort can be measured on a given ST (or any other bike). I can provide it – I just don't enjoy it but it would be an interesting metric to know. And I've done it with a pair of Clarks loafers and don't enjoy that either. So it's a 1/2" board and empty upper tank (not to mention solid soles) and I'm good with that.
