6: Wide-angle forward bend pose (prasarita padasana)
Benefit: Strengthens and stretches the legs, particularly the hamstrings, which are one of the tightest muscle groups in runners.
Technique: Stand with legs about five feet apart, feet parallel and toes pointing straight. Exhale as you bend forward from your hips, keeping your heels on the floor. Place your fingertips on the floor shoulder-width apart, chest parallel to the floor. (If you can't reach the floor, rest your hands on two blocks.) Exhale and lower your upper body toward the floor. Let your head hang.
7: Mountain pose (Tadasana)
Benefit: Helps achieve proper posture that will improve your running form. "Runners that plod along tend to roll their shoulders forward," Logan says. "Elite runners, by contrast, are in tadasana, whether they know it or not."
Technique: Stand erect, feet together and planted into the ground, heels, tailbone, and base of skull in a straight line. While standing in this position, try to extend your legs, lift your chest, and roll your shoulders back and down. Hold for one minute--but take it with you. "Be conscious of standing this way in your daily life, and while you're running," Logan says.
