Yoga for feet, ankles and calves is a great class for anyone. It's so important to bring awareness to our feet...most of the time, our foundation for many yoga poses plus we spend a great deal of time on our feet. If you wear shoes a lot (like most of us) then the muscles of the feet begin to atrophy. If you've mostly worn shoes for many, many years and you begin yoga later in life, you'll probably have a difficult time balancing until you start to strengthen the muscles in your feet. Ankles and calves need to be strengthened as well to keep us supported.
