The Rope Climb stuff.
RC PE1 Hinge Rows
Okay, the hinge row threads got my all confused so I settled on doing them with only my heels touching the ground. I'm not even sure if that's easier or harder now that I stop and think about it. Most importantly, is it correct? I let myself protract at the bottom of the rep, that's correct...right? Anyway, be harsh and clear, I won't be offended. Except about the fatness.
