How to Shovel Heavy Snow Like a Boss

My first article about shoveling snow described a technique I use to shovel faster with less stress on the back. That technique works great with lighter snow loads. We’ve been getting more snow in the Midwest recently so I wanted to go over another technique I use for heavier snow falls.

In the first technique, the back hand is tucked in front of the hip to better control the shovel. The other hand holds onto the shovel as close to the other end as is comfortable. On most snow shovels, this means the forward hand is still a distance away from the snow. While this is fine for lighter loads, it is less effective for heavier loads due to leverage issues.

To adjust for this, move the forward hand almost all the way to the snow end of the shovel and let the back hand go back behind your hips. This allows you to keep the load as close to your body as possible when lifting.

When you stand up and lift, keep the front arm straight so it acts like the hoist lines on a construction crane. This will reduce the work your smaller arms muscles need to do. On a crane, the lifting isn’t done by the hoist lines but rather by the motor that winds it up. The lines just transmit the forces to the load.

In this case, the “lifting motor” is your legs and your torso and arms transmit those forces. Your back hand functions to keep the shovel level and to steer it when you throw the snow away. When you pivot to dump the snow, you can use your hips and torso together. Since the load is essentially next to your body, twisting your torso won’t be as stressful on your body compared to the other technique where it is farther away.

This method should feel similar to lifting a box with proper form (using the legs, not the back). Your back and other core muscles just function to maintain your posture. They don’t do any lifting.

Finally, since your center of gravity is kept near your center of balance throughout the technique, you don’t have to reset your balance for each load. Essentially, you are just doing leg squats with weights. This allows you to perform each repetition more quickly.

Remember, if the snow is particularly heavy or high, shovel each spot in layers. Work all the way vertically down the snow pile before moving your forward. This technique is especially well suited for working vertically through snow since you don’t even need to move your feet for each repetition. Use this technique and you can plow throw piles of snow in record time!

Let it Snow - Safer, Faster Shoveling and Getting a Good Workout

We just had our first snow in the new year here in the Midwest. What a way to start off the new year. Snow and snow shoveling are simply a fact of Midwest winters. But that doesn’t mean you have to strain your back shoveling when the next snow storm comes to visit. In fact, you can turn it into a good opportunity to build some core and leg strength.

The key to shoveling snow safely is doing the heavy lifting with your legs. Your back isn’t meant to lift heavy objects. It’s especially tough with heavy snow perched far away at the end of your shovel—talk about poor leverage! Rather, your back and other core muscles (abs and obliques) are for maintaining your posture and enabling efficient transfer of forces through your body. In the case of shoveling snow, that means transferring the lifting power generated by your legs to your arms and hands.

With that in mind, let’s go over a better and safer way to shovel snow. Stand near the snow to be shoveled and place your left hand on the handle of the shovel. Keep this end of the shovel tucked against your body in front of your hips. This enables you to use your body weight effectively to maneuver the snow. Next, place your right hand on the shaft of the shovel, as near to the blade of the shovel as is comfortable. This arm only controls the shovel, rather than bending and lifting the snow, which is the job of your legs.

Now for the placement of the feet, which is important for balance and power. Put your right foot forward and left foot back in a wide stance. Then, squat down by bending your knees until the shovel touches the bottom of the snow. Keep your back as upright as you can; bending at the waist will lead to back strain. Center your weight between your feet to maximize stability and minimize the strain on your back when you lift. Push the shovel forward to load it with snow. Then, stand up by straightening your legs, keeping the front arm straight and back hand tucked into your hip. This movement should feel similar to picking up a heavy box with proper technique.

To dump the snow, simply pivot to the side by twisting your hips, not just your torso. For those of you familiar with martial arts, this movement is similar to the hip pivot from a back (60/40) stance to a high front or bow stance. Reset to the starting position and you’re ready for the next load. If you get tired on one side, switch your hands and feet and use your other side.

This technique minimizes movement of your back and smaller arm muscles, leaving the heavy lifting to your stronger leg muscles. It also uses your hips as a brace to reduce the effort needed to maneuver the loaded shovel. With a little practice, you’ll find that you can shovel snow faster since you don’t have to move as much with each repetition. As a bonus, you’ll get a great core and lower body workout at the same time!

If your legs aren’t strong right now, consider preparing for the snow by doing some leg strengthening exercises such as the Squat Progression from The One Minute Workout. Strong legs will help with everything, not just shoveling snow.

Remember, if the snow is deep or especially wet, work your way down in layers. There is no need to do the whole job at once. Take breaks as needed and go inside to warm up. And don’t forget to stay hydrated! When it is cold outside, it’s amazing how much sweat you can work up without noticing it.
