Stand tall with a flat back and braced core. Keeping your chest up and your gaze straight ahead, shift all of your bodyweight to your left foot. Bend the right knee, allowing the right foot to lift off the ground. Maintaining a flat back and a slight bend in your left leg, slowly hinge your hips backwards. Control your descent and inhale as you do so. Simultaneously, allow the right foot to counterbalance the shift in weight. Feel the stretch in your hamstrings and pause once your upper body is almost parallel to the ground. Reverse movement by driving the hips forward and bringing the right knee to your chest. Exhale as you do so.
