Tight hip flexors can inhibit the firing of glute muscles. Do this stretch after every run. Step forward and lower your back knee. Keep your knee over your ankle. Hold for 30 seconds on each side.
Stand on your left leg. Lift your right out in front of you. Stand tall (don't round your shoulders), and keep your left knee over your ankle as you lower down into a squat. Your hands can extend out for balance. Push into your heel to come back up and repeat. Start with shallow squats; go deeper as it becomes easier.
Side-Lying Leg Lift
Lie on your side with your legs extended out straight. Your lower arm can rest under your head; your top arm can rest on your hip. Lift the top leg up while keeping your hips steady and facing forward (do not rotate backward). Lower down and repeat. For an added challenge, wear an ankle weight.Sign up for your next race.
