If you have ever spent a winter driving in Minnesota, you can appreciate the need for traction. When you’re on ice, you can have all the horsepower in the world, but if your tires don’t have traction with the road, you’re going nowhere. The human body is no different. You can have a ton of strength in your hips, but without a strong and stable ankle, much of that power will never reach the ground. And, like a Honda Civic in 12 inches of snow, you’ll be going nowhere quick.
