What is the secondary muscle group involved during the incline bench press?

The secondary muscle group involved during the incline bench press primarily includes the anterior deltoids and triceps. When performing the incline bench press, the angle of the bench shifts the focus onto the upper pectoral muscles, but it also significantly engages the anterior deltoids, which are responsible for shoulder flexion and stabilization during the lift. Additionally, the triceps play a crucial role in extending the elbows as the weights are pressed upward, providing the necessary strength to complete the movement.

In contrast, while biceps assist in stabilizing the movement, they do not significantly contribute to the pressing motion itself. The pectoralis minor, although located near the working muscles, does not actively participate in the pressing action of the bench press. The latissimus dorsi, primarily involved in movements related to the back, does not contribute significantly to the incline bench press mechanics. Thus, the engagement of the anterior deltoids and triceps makes them the correct secondary muscle group during this exercise.
