Description
The Cable Lying Triceps Extension is an effective exercise performed lying flat on a bench using a cable machine to isolate the triceps muscles. It can be considered a cable variation of the classic skull crusher. Thanks to the constant tension provided by the cable, the triceps remain under maximum activation throughout the entire movement. Compared to the classic barbell skull crusher, it places less stress on the joints, offering a safer movement, especially for the elbows. It works all three heads of the triceps, providing a deep stretch particularly on the long head. When performed regularly, it significantly improves triceps hypertrophy, back-of-the-arm development, and isolation quality.
