While standing beside a wall for balance, bend your knee and grab your foot behind your back with the opposite arm. The key to doing this stretch correctly is to keep your abdominal muscles tight so you do not arch your back. Also, make sure to keep your knee pointing straight down towards the floor with both thighs as close as possible to one another. To increase this stretch, try pushing your hips forward a little.
Stretch should be felt along the front of your thigh.
