I have these shots I captured from my adventures training the other day. Rail balancing and walking is a simple, yet challenging exercise. Balancing is a great way to increase core strength/stability and alertness through your mind body connection.
I like balancing a lot. Mainly because it forces me to slow down-take my time- I must focus on precision and also being light and feathery in order to not make any sudden movements that may cause me to fall.
Even ignoring distractions such as people honking (which does happen) can show some symbolism as to why focusing on balancing can help you in focusing to get through some major life challenges.
