Where a woman might head out for a bracing hour of yoga or tai chi, her retired spouse is more likely to pursue a competitive activity with a little more at stake than just breaking a sweat. Sports like golf and bowling are popular for male retirees. Fishing is too, but the fish probably get more of a workout than the fisherman.
A 2003 study conducted by the Sporting Goods Manufacturers Association revealed other popular physical activities for men 55 and over: day hiking, fitness walking, calisthenics and recreational vehicle camping and hunting. Although it doesn't require sports gear, getting some of those chores off the honey-do list can provide a workout, too.
