Loss of Hip Extension (Piking)

This occurs when the hips flex excessively during the eccentric phase, creating a 'pike' shape. This significantly reduces the load on the hamstrings, shifting it to the lower back and glutes, and negates the primary benefit of the exercise for hamstring eccentric strength. It also increases shear stress on the lumbar spine.

Excessive Speed in Descent

Dropping too quickly through the eccentric phase reduces the time under tension for the hamstrings, which is crucial for building eccentric strength and injury prevention. It can also lead to a loss of control and increased risk of impact when catching yourself.

Incomplete Range of Motion

Stopping the descent prematurely, before reaching the maximum controlled range, limits the eccentric stretch and strength benefits. The greatest gains in hamstring length and strength occur at longer muscle lengths.
