Sweat Sessions

What kind of workout do you want?

Experts say the best exercise is the one you’ll actually do. “One big benefit of taking a fitness class is it’s an appointment on your calendar, so you’re more likely to show up,” says Kristie Willhoit, fitness specialist at Gwinnett Medical Center. “Think about your goals, and be realistic about where you are right now, in terms of fitness. Choose a class that will help you to be successful.”

Confused by the classes available? Here is a guide to some of the latest and greatest ones.


With a combination of shallow-water and deep-water exercises, these classes combine cardiovascular endurance with core stabilization, strength, balance and flexibility. Aquatics are especially great for those new to exercise, people with arthritis, or people who fear falling during exercise.
