Walking at Oxford Recreation Complex (Hix Gym). The gym is open from 5:30 am to 1:00 pm for Senior Adults, Monday through Friday. From 1:00pm to 5:00pm the gym remains open for walking for the general public. (Exceptions on days that require maintenance or special events are in progress) This facility provides shelter from the elements and a safe environment. Cushioned flooring minimizes stress to hips, knees, and feet - that is commonly a problem linked with walking on hard surfaces such as asphalt and concrete.
