Only persons in good physical condition and good general health should shovel. Whenever the snow begins to feel especially heavy, take a break. As with any moderate to strenuous activity, you should warm up before shoveling. Start by walking for a few minutes or marching in place. 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.
