Jane Fonda, at 86, is not quite doing her eponymous ’80s workout anymore. But it doesn’t mean she’s stopped exercising. “Slow—you’ll find out that’s the operative word,” Fonda told Julia Louis-Dreyfus when she was a guest on her Wiser Than Me podcast. “I do kind of the same moves, but slowly and with less weight.”
It’s smart to follow Fonda’s lead and adjust your approach to physical activity as you age. But you needn’t—and shouldn’t—wait till you’re an octogenarian to do so. Instead, think about recalibrating by about 55.
