AP - Older people would rather exercise alone than be surrounded by a bunch of youthful hard bodies in Spandex, suggests a study that examined how group fitness appeals to people of different ages.

AP - Like a lot of people, former flight attendant Mary Nicholson wasn't an exerciser. But two years ago she changed all that — at age 71. For Nicholson, part of the motivation to exercise was to be strong and agile enough to avoid a fall. "I'm bound and determined I'm not going to fall and break a bone," she said during a workout that included balancing on one leg, working with weights and stair-climbing.
