Older Adult Fitness

Our goal at the St. Peters Rec-Plex is to help you get the most out of your membership so that you can enjoy a healthy and active lifestyle.


Fitness experts recommend that older adults do moderate activity for at least 30 minutes a day on five or more days a week. As we age, it’s as important as ever to exercise regularly in order to avoid falls and injuries as well as problems such as heart disease, diabetes, colon cancer and high blood pressure.


All St. Peters Rec-Plex members enjoy access to our fitness equipment, rubberized indoor track, adult swim lap lanes, and more. LEARN MORE ABOUT REC-PLEX FACILITIES. You can also take advantage of our Personal Trainer on Duty and Body Basics class for beginners to learn how to use our fitness equipment—free of charge. CHECK OUT ALL OF OUR CURRENT CLASSES.


Plus, the Rec-Plex offers some programs that give active older adults even more options to reach 30 minutes of daily exercise!

We’ve added Active Older Adult fitness classes to our lineup of group aerobics classes FREE to Rec-Plex members. These are 30-minute classes, offered in the morning Monday through Thursday, taught specifically for active older adults. We’re getting great feedback from class members who say they feel better, stronger and more active because of these new Active Older Adult group aerobics classes.











The St. Peters Rec-Plex offers a Walking Club to help active older adults reach the guideline of at least 30 minutes of moderate activity, 5 days a week in order to maintain a healthy lifestyle. Walking is a simple, but important, way to stay active and fit by going at your own pace. The Walking Club is a fun way to meet that goal while also socializing and having a chance to win prizes!


Our Walking Club meets at 9:30 a.m. Monday through Friday on the indoor rubberized track. 


To earn miles in the Walking Club, be sure to swipe in at the Rec-Plex front desk and also sign in at the indoor track.


If you can’t make it to the Walking Club on weekdays at 9:30 a.m., but you still want to be part of the fun, you can choose a different time to swipe in at the front desk, sign in at the track, and walk for 30 minutes. Or, you can swipe in, sign in and attend 30-minute Active Older Adult fitness classes (see above).
