This is a loaded question because the answer is different for everyone, and it can slow change over time.
Probably the first exercise I can remember enjoying was doing workout videos at home. I had a couple Jane Fonda tapes I really liked, and I also enjoyed the Cindy Crawford workout video I had. Since then, I have had a myriad of exercise experiences I have enjoyed. Running was a biggie for a long time. I was the stereotypical runner in that all I ever wanted to talk about was running haha! I ran 5Ks, a half marathon, and a full marathon. I made it a point to run wherever I was, especially on vacation. I ran in Key West, northern Minnesota, Mumbai, Dubai, and London. I have also enjoyed Peloton workouts, boxing, and CrossFit.
The key to finding the most fun exercise is finding something that appeals to YOU. I loved running — lots of people despise it. And that’s okay. My best advice would be to try different things. I tried running so many times before I was successful at it. I would develop shin splints all the time so I would stop. When I would try again, I always spent some time researching how to avoid shin splints, and I kept going until I found something that worked. Boxing and CrossFit are also prime examples of trying something even though it’s way outside your comfort zone. I still remember my husband being incredulous when I told him I wanted to go try a ladies only boxing class. Boxing? Group fitness? Neither were anything I had expressed a great love for. But it turned out to be revolutionary — partly because of the activity and partly because of the culture at the gym I went to. CrossFit is a similar story. I had a stereotype of CrossFit in my mind — big, bulky, muscle types who talked in the weird CrossFit language, but it turned out there were just normal people at the CrossFit gym — big, muscle-y types and regular fir people and overweight people, young and old. And again, the culture of the gym I landed at was supportive and inclusive. So I probably ought to make sure I mention culture as a very important factor in finding an activity you love.
Keeping your body moving is probably the best thing you can do for your health. It’s what will allow you to get older and take care of yourself as much as possible — carry in groceries, get up if you fall, get off the toilet, get around on vacation — and it doesn’t have to be anything intense like boxing or CrossFit! Just walk, or do chair exercises, or ride a stationary bike — just do something!
Here’s to you finding YOUR most fun exercise!
