I might give that physics problem to my boys this week (I homeschool and we are doing physics and chemistry this summer): how much actual "weight" are you pulling when you drag 132 pounds across the floor? And the related problem of whether or not the weight being in a smaller surface area that contacts the floor has the same friction force as same weight with larger surface area (i.e., does a heavier weight per unit area create more friction?).

Sorry, we've been physics crazy lately around here! Really though, I love this idea of horizontal pull-ups, I can't do full vertical ones here at home (no equipment and no way to gradually work up to it), so this is very cool, thanks.

I do this!

I tried BJ's way too but there was not enough friction on my palms and wood floor so I was "clawing". I wore a pair of rubber gloves but that didn't work either.
Then I had an idea! I just bought a jacketed rope from AoS. I looped that around a post and dragged myself using the rope. I am sure I will not be able to climb a rope when it's vertical. Horizontal is easier. Next time, I'll put a face towel between my face and the floor.
O I like Calistro's suggestion! Where can I buy that?
