Other runners advise to stand on one leg with knee slightly bent and hold our other leg under or knee. Our hamstring is parallel with the floor. Of consequence, we would have to hold for two second and then we would bring our heel back under our knee. I'm curious to know what do you Think about this. I hope that all you are getting an effective stretching :)
A special good luck to Anne and Amy for their first half marathon :) Have a good running everyone!
