Hi again, those seem OK in some respects. The band on the feet one though is not really a functional exercise for the way the hamstring works or is involved in your discomfort. You need to consider 'Is the hamstring weak' or is it just functionally weak to due pain? If it is not weak it does not need to strengthen. It is perhaps overworked and might be stronger than the other side. I think the high stepping is a good way to go perhaps progressing that to a more plyometric movement e.g. small jump at the top (as symptoms resolve). Skipping might also be something to try if you want something extra that had a cardio element and also a calf/ankle component.

The stretch with the slightly bent knee is the true hamstring stretch which you can vary the amount of bend in the knee to alter slightly where you feel the pull. It seems that this one is telling us that it is indeed related to the hamstring origin issue.

Yoga ++ for patience. It's not what you gain with it, it's what you lose AND it's not so expensive ;-)
