So, JuJu, when I envision that, I think it's more of a pushing at the back of the stroke, than a pulling up. But then, as you lift your toes to get it over the gooey stuff, that's where the pulling comes in.

Hmmm. I'm going to visualize that while on the bike,

When I was consciously pulling up, it was all about the muscles on the top of the leg. Like I was lifting my feet while sitting so someone can sweep under my feet. I can see how different that would be when described as above. I think it's a matter of degree, but I think I am probably pulling up a little. I would like to maximize it, though.

Thanks!
