if you're so wrecked after a session that you can't fingerboard the day after then you were probably overdoing it.
Repeaters maybe, recruitment hangs no..
if you're getting pumped then surely by deffinition its not power endurance, its stamina work. power endurance is more like 8-18 moves.
I've always heard that in relation to power/strength work.. but I fail to see how you're going to get good at 20-80 move routes where you fall off due to pump without getting really pumped.. and then i'm usually too sore the next day to be really strong. Repeaters maybe, recruitment hangs no..Anacdotally, amongst my friends the ones who are the fittest are the ones who often wreck themselves whilst the strongest are the ones who stop strong etc..
Why not just do your recruitment hangs before a PE endurance session on the same day? Seems the easiest thing to do. Today i did 30 min maximal hangs in the am and am going to the wall for routes this pm, this way neither session interferes with the other which would be the case if i did it the other way round!
