Stretches to Gain Flexibility

Standing Hip Flexor Stretch

Your hip flexors - muscles that help you lift your knees and bend waist - can get tight if you're a runner or you sit for long periods. Drop one leg back, keeping it straight or slightly bent. Try to keep your torso upright and your spine straight. Drop your tailbone down toward the floor and tuck your butt forward until you feel the stretch of the inside thigh of your rear leg. Hold for 20 to 30 seconds and then switch legs.
