I like to start with a active stretch for the back of my legs after a run; it just feels good to keep moving a bit.
- Standing on your right leg, step your left leg forward with your toes flexed.
- Reach your left hand to your toes, keeping your back flat — you should feel a gentle stretch in the back of your thigh. Hold this position for just a moment, then place your left foot next to your right as you return to standing upright.
- Switch sides to stretch your right hamstring. Continue alternating sides for 20 to 30 seconds.
