The kneeling cable triceps extension is an single-joint exercise meant to isolate the triceps muscles, using a high pully on a cable stack and a bench. It can also be performed in a tall-kneeling stance from a low pully. It is most commonly used in muscle-building triceps or overall arms workouts.
Benefits
Emphasizes stretching the triceps under load, which can increase muscle growth
Constant tension throughout movement, including at peak contraction
Easy to change weights for dropsets
Stabilizing elbows against bench can make it easier to focus on mind-muscle connection
