LEWISTON — HealthSteps, part of the prevention and wellness services offered through St. Mary’s Health System, offers a wide variety of classes for adults. Among them are aquatic fitness and lap swim, available with a core membership.

Aquatic fitness offers a toning, calorie-burning workout. While swimming skills are not needed, a comfort level in both deep and shallow water is important. Classes are offered from 6:30 to 7:15 a.m. Mondays, Wednesdays and Fridays and from 11 to 11:45 a.m. Tuesdays and Thursdays.

During lap swim, adults may swim at their own pace in the 25-meter, eight-lane pool, supervised by a certified lifeguard. Lap swim is scheduled from 6:05 to 7:30 a.m. Mondays, Wednesdays and Fridays and from 6:05 to 7 a.m. and 11 a.m. to noon Tuesdays and Thursdays.

Swim classes are held in the Bates College Merrill Gymnasium.

All instructors are certified and can lead participants through a safe and productive workout no matter what the fitness level. For more information or to register, call HealthSteps at 777-8898 or visit www.stmarysmaine.com.
