​Do you want to be the grandfather wrestling with your grandkids, or the one who can’t lift them because of a bad back? Do you want to watch them play superheroes, or help them vanquish the bad guys? How many years of your grandchild’s life do you hope to be around for? If you haven’t been motivated to take good care of yourself, perhaps being a grandparent is the inspiration you need. Would you take up exercise to squeeze out a few extra years?
 
I’ve always hated exercise. That endorphin rush that you read about has never happened for me, and the only physical exertion I’ve ever actually enjoyed is kayaking in still waters. Which, since I don’t live near still waters, is not something I can pursue as a regular workout. I was lucky: my genetics meant that even without a vigorous exercise program, I stayed healthy and strong for the first fifty years of my life.
 
Eventually, however, my excellent genes began to age. I found myself having trouble lifting my suitcase into the overhead bin. I got stiff if I sat on the floor too long. And then my grandson arrived. I realized that to be part of his world I would need to be able to carry 30 pounds and spend long stretches sitting on the concrete with a fat piece of chalk in my hand. And I joined a gym for the first time in my life.
 
Pilates, yoga, weight training: these are all excellent ways for older adults to keep fit enough to play like a toddler. The average age that someone becomes a grandparent today is 50, hardly a senior citizen. No matter what your age, though, staying in shape is a powerful gift to your grandchildren. Getting down on the floor allows you to see the world from their vantage point and be a part of their world. Being able to get up again without difficulty is a bonus!
