With the Diamond Yoga Pose from a seated position bring the soles of the feet together and bend the legs slightly so that there is a big gap in front of you. Sit with back straight lower ribs lifted and chest open. Put your hand on your knees and as you breath out fold forward and take hands down towards feet.
Be very careful on this one no sudden moves take it slow as there is a slight twist in the hamstring and sudden movements can cause damage to them.
If you get to a point where you feel the hamstrings complaining ease off slightly and use another breath to see if you can go further.
Fold as far forward as your body will allow and rest arms in the gap in front of you.
