When? Do these on toprope or bouldering close to the ground, so you can focus on the movement instead of worrying about falling. Set aside dedicated practice time two or three times a week; you can easily incorporate the exercises into a 20- or 30-minute warm-up. Pay attention to how your body feels (sensory feedback) while performing the drills, and practice them frequently. Your new skills won’t become part of your on-the-rock repertoire unless they are natural and familiar. You can accelerate this by attempting these drills on increasingly difficult terrain.
