What is the rationale for using a 45-degree incline during tabletop tasks for strengthening the triceps?

• A. It requires the triceps to work against gravity.
• B. It eliminates gravity.
• C. It eliminates resistance.
• D. It places the hands below elbows.

Answer: (A)

The main idea is to use gravity as the loading force to strengthen the triceps during elbow extension. When the tabletop is set at a 45-degree incline, gravity creates a component of force along the direction of the forearm as you try to extend the elbow. That means the triceps must contract to push the forearm upward against that downward pull, providing a consistent external resistance that challenges the elbow extensors and promotes strengthening. On a flat surface, this gravitational resistance is less pronounced along the extension motion, so increasing the incline adds load rather than eliminating gravity or resistance. The arrangement also isn’t about placing the hands below the elbows; the key is that the incline makes gravity work against the triceps as you extend.
