Stretch the muscles in your arms and legs, as warm muscles will work more efficiently and are less likely to be injured. Wet snow is much heavier than dry snow. Govern your shoveling accordingly. Push or sweep away as much of the snow as possible. Drink plenty of water.
Dehydration is an issue in cold winter months just as it is in the summer.
When shoveling, stand with your feet about hip width for balance and keep the shovel close to your body. Avoid twisting movements. If you need to move the snow to one side, reposition your feet to face the direction the snow will be going. Wear appropriate footwear, and exercise caution to avoid slipping or falling. Make use of ice-melting materials to make the job as easy as possible.
