Many people only think about gymnastics once every fourth year, when it is one of the most popular sports in the olympics. But events for gymnastics, both professional and amatuer, are happening all the time. Gymnastics Day is a holiday that celebrates gymnasts and the incredible athletic ability they possess. Celebrate it by going to watch local gymnastics competitions or getting your kids into a gym to learn some gymnastics themselves. Some gyms may offer free or discounted lessons on this day.
