|Here's some good balance exercises:
Begin with your planted foot turned outside to a 45 degree angle with your knee slightly bent. Project your other leg forward, locking your knee by pushing with your heel and pulling your toes back towards your shin. Sit back as much as possible without leaning. Flex your raised quad and planted glute in order to relax the hamstring of the raised leg. Exhale and grip the ground with your toes.
