By far, my favorite stretch to do after a run is anything that involves my hips. If you own a treadmill, try this the next time you finish a run. Of course you could do it at your gym, too, if you feel comfortable, but if not, you can do this stretch on stairs instead. Also, if your hips are really tight, you may want to place your top leg up on something lower, like a bench or chair.

• Before doing this stretch on a treadmill, make sure to turn the machine off and stand firmly. Keep your left foot planted and bend your right knee, lifting your foot up and stepping it onto the front of the treadmill.
• Bring both arms so they're on the inside of your knee and draw the weight of your torso forward. You'll feel this stretch in your right hip and your left hip flexor.
• Stay for twenty seconds or longer if you love it. Then do the other side.
