They may not be on the fast track anymore, but they aren't ready for the junk yard. In most cases, all baby boomers need is a tune-up and, in a way, Cindy Schulze is in the restoration business. She a certified instructor who conducts a franchised exercise program called Jazzercise Lite and, although it can be used by all ages, she has been concentrating on an age group whose only physical activity may have been walking to the mailbox to get a Social Security check. "I really love this group because they're not in the fast lane," explained Schulze, who walked away from the business world after she joined a 50s-something crowd last year. Jazzercise Lite is geared toward aging baby boomers, people with special needs and people who have gotten out of shape. "They're not gym people," Schulze said. There isn't any impact hopping, skipping or strenuous routines commonly associated with aerobics. Instead, the program is designed for cardiovascular improvement, stretching and strengthening muscles. Karen Frick has been a Jazzercise Lite regular for more than 10 years. "It just gets you warm and tingling all over," she said. "I feel like this has kept me in shape and really healthy. Before I started you couldn't have told me how much better I'd feel about myself." All the exercises and movement are controlled by the participants. "We talk about listening to your body," Schulze explained. "It depends on how hard you want to work. How high you want to lift your knees, how large you want to make your steps or how deep a lunge you want to do." Even though they aren't rookies at life, there are newcomers that might need a little encouragement. "Some people think they can't do it or that they can't keep up," Frick added. "I tell them to start out in the back of the room and they'll learn." Even if beginners don't recognize the routines at first, they should be familiar with the music. "We mix some old stuff with some new stuff as well as jazz, dance and country," Schulze said. "They love it." Classes meet at 9:30 a.m. on Tuesdays, Thursdays and Fridays at the Centerpointe Dance Studio on the Elliott-Warner Loop at Equestrian Trail and, starting on March 3, at 9:30 a.m. Monday and Wednesday at the Desert Foothills United Methodist Church, 2156 E. Liberty Lane. Information is available via email at email@example.com.
