You can learn alot by observing! One evening I was watching a TV interview of Hicham El guerrouj, the Maroccan Middle distance runner when I saw him do the following leg stretch.

This is my favourite leg stretching exercise. The benefit of this leg stretching exercise is that you stretch the arms, legs and the back at the same time.
Benefit of this leg stretch
1. Relieves leg pain and lower back pain
2. Reduces risk of injury
3. Opens important energy channels from your spine to your feet.
4. You get the benefit of working three muscles at the same time. Saving your precious time
One important thing to remember when stretching, “Stretch slowly, gently & smoothly”
