Loads hamstrings at the hip joint with a 10:1 lever ratio — the hamstring insertion is roughly one-tenth the distance from the hip to the barbell on the shoulders. This maximizes hamstring stretch-under-load at the bottom of the movement.
10:1 hamstring lever at the hip — enormous internal tension per kilogram of external load.
Stretch-under-load 12/15 — the stiff-legged position stretches the hamstrings to near-maximal length under tension, the strongest hypertrophy signal.
Complementary to knee-based hamstring work — loads hamstrings at the hip joint, paired with exercise 5 which loads at the knee.
Placed fourth to start the hamstring block with the highest-scoring hamstring exercise.
