If you have tight hamstrings, please watch this video first (for all the details), and then play it again, and follow along. Make sure you attend to the small details—this is what will make the difference.

Once you have stretched one leg, play the video again and do the second side. If one side is noticeably tighter than the other, repeat for this side (so tighter side gets two stretches). In time, both legs will get closer together in function.

Do this sequence only once a week in the beginning, because if you do get deeper than normal, you will be muscularly sore tomorrow (and maybe even the next few days). We have found that there's no point in stretching sore muscles, but any limbering (mobility) practises will be fine. A hot bath with Epsom Salts is good, too.
