Final answer:
The proper execution of the single-leg Romanian deadlift will dynamically stretch the hamstrings.
Step-by-step explanation:
The proper execution of the single-leg Romanian deadlift will dynamically stretch the hamstrings. This exercise involves bending forward from the hips and lifting one leg behind while keeping the back straight. As the leg is lifted, it requires the hamstrings to lengthen, which provides a dynamic stretch.
