HOW: Grab a relatively light kettlebell or dumbbell. Begin in a standing position holding the kettlebell between your legs. As you hinge through the hips, keep your spine and legs stiff. Push your bottom back slowly until you feel a stretch in the hamstrings. Hold the bottom position for a few seconds before pulling back up.
FEEL: You will feel a stretch in the hamstrings as you move into the hinge. You may feel the lower back muscles, glutes, and hamstrings working when moving back into a standing position, but this should be minimal with relatively light weight.
COMPENSATION: Do not bend the knees or flex through the trunk.
