A stretch for the hamstrings, avoiding the common "mistake" of bending forward. You can make this stretch more specific to the lateral portion of the hamstrings by turning your toes further in, or bring the stretch to the medial part of the hamstrings by turning your toes outwards and drop your hip on the side of the high leg. The stretch should always be comfortable and never forced. Always do both legs and remember to even tensions in the leg by also stretching your quadriceps (front of the thigh). To use at your own risk.
