Ron Stoffer and Ralph Davis work out on the treadmills. W ith renovations to its health clubs shaping up, the Jewish Community Center must now convince ex-members and non- members that the clubs pass fitness muster. The hurdles are high but are by no means insurmountable. Obviously, the JCC must compete with other health clubs like the Sports Club of West Bloomfield, where many former JCC members are said to belong, Franklin Racquet Club, Powerhouse Gym, Gold's Gym and others, said JCC Executive Di- rector David Sorkin. "In the past, we didn't have to have the best equipment because when you came, your chaver (friend) was there. We have to be competitive with early childhood care, too," he added. He pointed out that socio-economic shifts have sent women into the workplace and into the workout clubs, necessitating the expansion of both fitness and child- care areas. When the West Bloomfield JCC was built in the early 1970s, it was a "man's world," he noted. And today, Jews are no longer unwel- come at private clubs. In early 1995, the Center offered a two- for-one membership deal. Early this year, it opened its doors to non-Jews. Beginning last month, the JCC began offering a 30- percent discount on health-club member- ships to new members. Since August, the JCC has spent $200,000 on new exercise equipment, $25,000 of which was installed at the 3- year-old health club at the Jimmy Pren- tis Morris branch in Oak Park. By the end of the month, the updating of the locker rooms and recarpeting of the health club at Maple-Drake in West Bloomfield will be finished. That branch is also scheduled to get the "Cardio Theater," which allows exercisers to plug individual headphones into the TV program they wish to watch. That would be a good thing for Dr. Shel- don Gonte, a 6-year health-club member who wears headphones to block out the incessant noise from the TVs. "Here I am working out, I'm listening to CNN, and I've got a headache," he said. While Dr. Gonte likes the Maple-Drake health club offerings, he wishes the Cen- ter offered more family-oriented activities. Bringing his 4year-old daughter to swim isn't easy because he must navigate through the women's locker room. He also wishes the babysitting hours were ex- tended. `That's why membership is down. How many 30-year-olds do you see here?" he said. Other health-club members at Maple- Drake and JPM complain about the lack of younger members, odd hours, mediocre aerobics classes, high membership dues and occasional waits to use machines. Yet, none plans to find another club. "I think it's fun that they're trying to improve, but I was not unhappy with it before. I know a lot of other people were," said Susan Grant, a West Bloomfield mother who works out at Maple-Drake four or five days each week. Ilene, a longtime Maple-Drake health club member who did not want her last name published, said club hours on Fri- day, in particular, are "unattractive" for working people. And the best aerobics classes are taught before most people have left work for the day, she said, explaining that the evening classes are not as rigor- ous. "I used to see a lot of people I know, but a lot less people are here now," she said, adding that many of them belong to the Sports Club. Attorney Michelle Zeltzer, 25, returned from California a few months ago. She's been working out at Maple-Drake since her parents bought her a JCC health-club membership. "It's not a bad health club, but there aren't many around here that aren't," she said. Ms. Zeltzer believes the JCC is too ex- pensive, but neither the nearby Sports Club ("too gossipy") nor Powerhouse Gym appeals to her, and she wishes there were more younger members.
