Your quadriceps (front thigh) muscles work hard when you're running, so they'll need a good stretch when you're done. Here's what to do:
1. Stand straight, lift your right foot up behind you, and grab your right foot with your right hand.
2. Pull your heel gently toward your butt, feeling a stretch in your quadricep (front thigh).
3. Keep your knees as close together as possible.
4. Hold the stretch for 15 to 30 seconds.
5. Repeat with the left leg.
