A hand balancer from Russia, Nikita Sukhanov, recently released a new video full of powerful balancing moves on hand balancing stands performed in a controlled manner. My favorite parts are at 0:43 and 2:55.
Apart from great strength and coordination, these and similar hand-balancing moves require a great deal of flexibility. If you’d like to increase ranges of motion, decrease pain and become MUCH more flexible, make sure to check out GMB Focused Flexibility.
