Romanian deadlift
This exercise differs from the traditional deadlift in that the legs are more or less fixed during the lift. The knees should be slightly bent, but this is more of a pulling exercise that engages the hamstrings and glutes. It probably even targets the hamstring more, but it also needs to be developed to increase overall performance.
How to do this exercise:
Hold the bar at hip height with a straight grip (palms down). The shoulders should be lowered, the back straight, the stomach tense, and the knees slightly bent. This is the starting position.
Lower the bar down, pulling the pelvis back as far as possible. Keep the barbell close to your body, looking straight ahead and not raising your shoulders. Lower until you feel the hamstrings are fully extended—usually just below the knees.
At the bottom point, squeeze the buttocks and use the back of the thigh to begin to rise.
