With that diverse clientele in mind, the Y is again redefining itself. A new strategic plan envisions the organization as America's paramount fitness and anti-obesity crusader, combatting what it calls "the nation's ongoing lifestyle health crisis."
While maintaining its varied youth programs and vast child-care network, the Y is aggressively expanding health-related initiatives, notably through a program called Activate America.
At hundreds of local Ys nationwide, officials are retraining staff, redesigning facilities and revising activities to better serve the millions of Americans who find it hard to stick with weight-loss and fitness regimens.
"Our history has been one of taking a lead on key issues facing our society," said Neil Nicoll, who since May 2006 has been president of the YMCA of the USA
- the parent group that coordinates activities of the 967 independently run YMCA associations across the country.
Founded in Britain in 1844 by Christian evangelicals, the YMCA opened its first U.S. branch in Boston in 1851 and soon adopted as a goal "the improvement of the spiritual, mental, social and physical condition of young men."
It established hotel-like residence halls, organized summer camps, and oversaw the invention of volleyball and basketball. During both world wars, it deployed thousands of volunteers to provide services for U.S. troops and war prisoners.
One by one, barriers to participation fell - women and non-Christians were welcomed, and in the 1960s the Y greatly expanded inner-city operations. By the 1980s, it was embracing the fitness boom, and building many new facilities.
Now, more than 370 of its associations already have joined Activate America, which Nicoll said is targeted at the 40 percent of Americans who crave a healthier lifestyle but waver in their pursuit of it.
"A lot of our population doesn't respond to what your gym teacher told you," he said.
"They're looking for personal support, done in a more holistic way. We want programs geared to group activity so people can develop connections instead of just running in and out."
One example: the YMCA of Greater New York in September began offering a 12-week, personalized exercise program
- free to members - that includes four individual sessions with a fitness coach.
In Anderson, S.C., the Y is holding monthly weigh-ins as part of a communal weight-loss drive. Other Ys are reassessing the nutritional value of food offered in their vending machines and at their child-care centers.
Karen Leslie, CEO of YMCA of Greater Providence in Rhode Island, said the initiative means her nine-branch association will focus less on gung-ho fitness buffs and more on those who struggle to achieve good health.
