This common runners stretch really hits the hamstrings and glutes, and helps prevent lower-back pain.
- Sit with both legs extended in front of you. Bend the right knee placing the sole of your right foot against your left inner thigh.
- Fold over your left leg. Rest your hands on the floor on either side of your leg or on your shin, or wrap your hands around your left foot.
- Breathe deeply, performing this stretch for three to four minutes on each side.
