How do you climbers stop forward head posture from climbing emphasising the pre-existing muscle imbalances of nerd neck? The prevalence of this in my climbing gym (70% of the climbers) put me off the sport.
I think attending ballet lessons for beginners will help fix your nerd neck. The first thing a ballet instructor teaches is how to hold your head correctly and how to stand correctly. They will definitely train the strength of your ankles and feet too. You will like it!
