Problem selection:
Select problems based on your plan. 6-8 moves. Avoid problems with dynos or excessively large moves. The problems may need to be very easy for the drill to work right. Be humble and start easy.
Climbing cadence:
Rest as much as needed in between attempts until you reach the intended number of repetitions or time. This is a maximum strength exercise. You should not feel pumped or out of breath.
Focus:
On each move, hover your hand over the target hold for 3 seconds before grabbing it. Continue breathing and try to keep as much of the body relaxed as possible.
Ideally use 15-40 degree overhanging walls.
Combination:
Perform at the beginning of your session, after warming up fully and after any finger strength work.
