常见错误
Lower Back Rounding
Rounding the lumbar spine under load is the primary cause of deadlift-related disc injuries. It shifts compressive and shear forces onto the posterior elements of the spine.
Bar Drifting Away from the Body
Allowing the bar to drift forward increases the moment arm on the lower back, dramatically increasing injury risk.
Jerking the Bar Off the Floor
Using a jerk start creates a sudden spike in spinal load and bypasses the proper tension-building phase.
