Want to be more consistent with dynamic movement?
Have you ever missed the sweet spot on a hold when being dynamic at the gym (or on rock)? We certainly have in the past.
Rather than focus on the hold in general, work out the exact spot you want your index finger to hit/connect with. Focus on it.
We are far more coordinated with our index fingers due to daily tasks, our proprioception is far better and as a result the rest of the hand will follow.
Aim with that finger, keep focus and enjoy being more accurate and consistent!
