Don’t Use a Long Stride
Leaping forward while you run is inefficient and an energy drain. Instead, stand tall and lean forward, and when you feel like you are going to fall, step forward just enough to catch yourself. This should be the length of your stride. It takes less energy to fall than to reach your foot in front of you.
Do Take Short Effective Strides
Less motion through the joint means less wear and tear and improved efficiency during your runs, says Figueroa. Using a shorter stride reduces the movement within any joint (for running, this means the joints of the ankles, knees, and hips), and less movement means a longer, healthier life for these joints.
