To understand why the overhead triceps extension is essential for any triceps workout, we spoke with Luiz Silva, a personal trainer, spin instructor and certified strength and conditioning coach.

That puts the main point of focus extension. The biceps curl, on the other hand, emphasises bending the elbow to bring the forearm closer to the upper arm, making it an extension-focused movement.

That greatly expands the benefits of movement snacks on muscle mass. “Our results highlight the importance of breaking up prolonged sedentary periods with brief activity snacks,” he added.
