Fitness Classes Offered
Morning Water Exercise
7:30 – 8:30 am Monday – Friday
By combining the elements of movement and water, you will improve muscular strength, endurance, and flexibility as well as cardiovascular performance. This program is especially beneficial for those who have not been physically active, those who suffer from arthritis, back discomforts, and/or other physical limitations. No swimming skills are necessary and only those participating in the class will be in the pool during this time. Water exercise is a low impact exercise designed for all fitness levels. The buoyancy effect of the water increases benefits by applying minimal stress on the feet, ankles, knees, and hips.
Evening Fitness Classes – Aqua Zumba/Water in Motion
6:30 – 7:15 pm Tuesday and Thursday
Teachers may choose to teach either Aqua Zumba or Water in Motion
Aqua Zumba
Splash your way into shape with an invigorating low impact aquatic exercise. Known as the Zumba “pool party”, the Aqua Zumba program gives new meaning to the idea of a refreshing workout. Integrating the Zumba philosophy with traditional aquatic fitness disciplines, Aqua Zumba blends it all together into a workout that’s cardio-conditioning, body-toning, and most of all exhilarating beyond belief. Using a combination of exercise and aerobics techniques, you get a vigorous workout with the added resistance of water. Your instructors will occasionally add use of resistance bells or other apparatus to get specific results within the workout. No special skills are required. Swimmers and non-swimmers alike are welcome to participate. Aqua Zumba offers a more vigorous workout while still being appropriate for beginners; you work at your own pace. Members that take this class may also take advantage of our incentive program.
Water in Motion
Water in Motion will change the way you look at aqua exercise! This workout provides a low impact, high-energy challenge for participants of all ages, skill and fitness levels. The choreography and music is refreshed every three months, so jump in and make a splash with this dynamic cardiovascular workout that tightens and tones the entire body. It’s more than just another aqua class, it’s a pure fun, 45 minute water extravaganza! Water in Motion offers the benefit of a high energy calorie burning workout without the pull that gravity plays on the body. Experience the cross-training effects that water provides, reducing the impact on your joints, specifically the knees and back.
