흔한 실수
Rounding the Lower Back
Allowing the lumbar spine to flex (round) during the eccentric (lowering) phase places excessive shear stress on the intervertebral discs. This significantly increases the risk of disc herniation, bulges, and chronic lower back pain, while also reducing hamstring and glute activation.
Squatting the Movement
Excessive knee flexion turns the RDL into more of a conventional deadlift or squat, shifting the emphasis away from the hamstrings and glutes towards the quadriceps. This reduces the intended hamstring stretch and limits the effectiveness of the exercise for posterior chain development.
Bar Drifting Away from the Body
When the barbell drifts too far forward from the body's center of gravity, it creates a longer lever arm, significantly increasing the load on the lower back and reducing the mechanical advantage. This compromises form and increases injury risk.
