Problem selection:
Select board or spray wall climbs that are easy for you with down-pulling holds and uncomplicated sequences. Some crossovers, bump sequences, etc. may need to be performed normally, with no snapback. Problems should be 6-8 moves.
Use your judgment on which moves make sense for the drill, and use all footholds if needed to make the difficulty correct.
Rough estimate: for a climber who can do a 7C/V9 problem, perform on ~6C/V5 problems. For a 7A/V6 climber, perform this drill on 6A/V3-6B/V4 problems, with any feet. It should be hard, but not desperate.
Climbing cadence:
Rest as much as needed in between attempts until you reach the intended number of repetitions. This is a maximum strength exercise. You should not feel pumped or out of breath.
Focus:
After you do each move, prepare your feet for the next move, then remove the hand you’re about to reach with. Let your body sink into the fixed arm and establish a relaxed, “reset” position. Now snap back up towards the target hold, generating momentum with the hips, upper body and free arm as needed.
Combination:
Perform at the beginning of your session, after warming up fully and after any finger strength work. Do not combine with one-arm training.
