Focus on the movement of shoveling snow, what is the best way to swing the shovel and not strain your back. Make a workout out of the chore for myself. Keep my back straight, sit back and use my legs to get lower when scooping snow. Count reps, 20 on the right side and then switch to the left side. Doing this will keep you mind occupied while doing such a repetitive task.
See how fast you can get the drive shoveled. I go for a PR each time I go out the door with my shovel. It’s not that I find soooo much enjoyment from clearing the drive etc. I want to get it done and this is the fastest way I can get myself to complete this mundane task. If you must do the chore… get the most out of it.
