The debate over the best running form has gone on for many years. The best way to run is a style that employs good posture, conserves energy, and avoids injuries. Maintain a relaxed, upright position without leaning forward or back, which can strain your neck and core muscles. Keep your shoulders and arms loose—don’t tense up and don’t clench your hands. Avoid twisting your body as you run, and don’t stretch your legs too far out with each step. Your gait should feel natural. As your running improves, your cadence, or number of foot strikes, should increase as well.
If you’re concerned about your running form, or have any foot or lower leg pain when you’re active, don’t wait for problems to develop or worsen.
