ON Wall Street, when the going gets tough, will the tough get yoga mats?

Adding classes in yoga, meditation and other so-called mind-body regimens is just one way fitness professionals in the financial district are responding to recent economic uncertainties roiling their corporate clientele. Some are also offering shorter, cheaper personal training sessions and, in at least one health club, quiet discounts for members who lose their jobs.

Amid layoffs, concerns about staying buff could seem trivial. (Imagine the headline “World Markets Near Collapse: Muscle Tone Under Threat.f221;) Yet, businesspeople themselves wonder how a perilous financial climate will affect their physical fitness  and if exercise could help them weather hard times.

Some struggle to squeeze in any workouts at all. But others, like Amy Sturtevant, an investment director for Oppenheimer & Company in Washington, find themselves doubling down on conditioning for relief. “Professionals are doing their best not to panic, but I know a lot of professionals who are panicking” about the markets, she said. “The only way to get away from it is to have some kind of outlet.”

Ms. Sturtevant, a mother of four, is training for her fourth marathon. With brokerage clients needing more hand-holding, she said, she stints on sleep rather than skip her 5 a.m. daily boot camp and 20-mile weekend runs.
