A study published this year followed over 5,400 women, ages 63 to 99, for eight years. The quarter of them who could stand up from a chair fastest, five times in a row, no hands, had about 37% lower odds of dying during that stretch than the slowest quarter. Grip strength told nearly the same story, about 33% lower. My take: this isn't about how your arms look in a sleeveless shirt. It's about whether you can still get off the floor to play with a grandkid, or hoist a suitcase into an overhead bin. One of my longtime students, mid-70s, still gets up and down off the floor without using her hands. Her own words about women her age: "there's no freaking way" most of them could do that anymore. Honest caveat: this particular study only looked at women, and the average age was almost 79, older than most of you reading this. So if you're 55 and this test feels wobbly, that's useful information, not a verdict. I found yoga because my joints wore out. I was a full-time parachute rigger, which means a lot of work for the arms and hands, and one day I could not even lift my coffee cup. And I love my coffee, so I had to do something. That’s how I found yoga. A few years later I quit rigging and became a yoga teacher instead. So when I say strong, I don’t mean impressive. I mean the kind that lets you lift your cup, get up off the floor, and keep going. One thing to try today: stand up from a chair five times in a row, no hands, no pushing off your knees. Notice how it feels. If it's shaky, hold the back of a chair and check with your doctor or PT before you push further. Come find your own version of strong in the classroom this week, whatever calls to you.
