Making fitness matter for 5-9 year olds. The benefits of exercise are huge! School Gym will get their hearts pumping, lungs working, increase memory, and concentration, strengthen muscles, joints, and healthy bones, promote self-confidence and self-esteem, and lower stress levels. Cool dances and aerobic routines are motivating workout breaks for school-age kids, offering balance from studies and time in front of the TV and computer. The U.S. Department of Health recommends 60 minutes a day of physical activity. Make time for School Gym and make exercise a daily priority for a healthier life.
