What kind of pulling are you doing when you're conditioning?
I rarely see anyone mention doing any sort of metabolic conditioning circuits anymore on this board.
Even outside of the CF world most of the metabolic stuff I've seen people mention on discussion boards, blogs, website etc. involves strict pull ups, body rows etc. Rarely are there any sorts of high rep deadlifts in a circuit format, and even more rare to see high rep oly lifts. And nobody really does kipping pull ups anymore.
If your hands are taking a beating doing strict pulls in a conditioning workout, then there are a couple options.
A) Stop doing them.
B) switch to strongman medleys and save up to buy a Prowler.
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
