直臂下壓 — 動作分析

Bending the Elbows Excessively

Excessive elbow flexion (bending) shifts the emphasis from the lats to the triceps and biceps, reducing the isolation of the target muscle. This can lead to less effective lat development and potential elbow strain.

Using Too Much Momentum/Body Sway

Swinging the torso or using hip drive to pull the weight down indicates the load is too heavy or control is lacking. This reduces lat activation, increases risk of lower back strain, and turns the exercise into a less effective full-body movement.

Shortened Range of Motion

Not fully extending the arms overhead at the top or not pulling the bar down to the thighs at the bottom limits the stretch and contraction of the lats. This compromises muscle development and the effectiveness of the exercise.
