The most important aspect of being fit enough to shovel, however, is to be fit enough to enjoy life. You don’t have to be the fittest that you can be, but you should be “fit enough.” Fit enough to walk, to dance, to enjoy life and yes, to shovel. Get some type of exercise a few times a week, stretch afterward (while your muscles are warmed up) to stay flexible. And while you’re out there. Have a snowball fight with your kids or grand kids, build a snowman, or a snow fort, and find a way to laugh and socialize.
