Winded, shoveling snow, how can I exercise?

Start small. Walking helped me tremendously. Started walking a slow and easy mile and slowly increased to 4 miles. Helped me greatly with endurance and fitness levels that I was able to start running and complete a 5k.

It's all about making progression. Don't push too hard or go balls to the wall. Just start with what you can do and slowly increase from there.

Shoveling snow is different from walking on a treadmill, a light jog, or yoga. You'll be fine. Start slow.

I'm quite active, but shoveling snow is one of the most intense exercises I've done!

I've shoveled heavy, wet snow while wearing a heart rate monitor. The calorie burn per hour - one measure of how hard the work is - exceeded the burn rate from spin class, rowing hard but below competitive race pace (I row on water and machines - race pace is close to heart rate max), or biking on a heavy hybrid bike at >10mph!

So, +1 to the idea that you can get some exercise, just start slowly with something that's not as intense (!), then progress gradually as you are able. I wasn't always able to do all the things I do now, but over time, lots has become possible . . . and you're much younger than I (I'm 60 y/o);
