What are two common errors during the triceps cable push-down exercise?

The correct choice highlights common errors that can occur during the triceps cable push-down exercise, particularly regarding improper shoulder positioning. Flexing at the shoulder can lead to a less effective triceps contraction because this position shifts some of the workload away from the triceps and can compromise the exercise’s targeted muscle activation. Additionally, extending the shoulders can both diminish the intended focus on the triceps and potentially increase the risk of injury by placing undue strain on the shoulder joint.

In contrast, extending the legs, rotating hips, flexing the hips, and extending the knees do not directly relate to the biomechanics and alignment needed for a proper triceps cable push-down. Proper form is essential, as these kinds of movements can be more characteristic of leg exercises or may simply not be applicable to the upper body-focused triceps push-down. Hence, awareness of shoulder movement is crucial for maximizing the exercise’s benefits and ensuring safety.
