Classify gyms and leisure centres in the "Essential services sector"

Physical exercise of all types is a major release for those who partake in all forms of training.
Professionally designed training and dietary programs provide an integral part in preventing many diseases as well as having a major positive influence on mental health. All of these factors significantly improve the health and well being of all those who use Gyms which in turn has a direct benefit on easing NHS interventions on the treatment of many diseases.
