The tibialis anterior muscle is primarily responsible for the movement during a seated toe raise. This exercise involves dorsiflexing the foot, which is the action of raising the toes upwards towards the shin. The tibialis anterior is located on the front of the lower leg and plays a crucial role in this movement by contracting to lift the foot.

In contrast, the gastrocnemius is more active during plantarflexion, which is the opposite movement involving pointing the toes downwards, typically seen in exercises like calf raises. The biceps and triceps are upper arm muscles and do not engage significantly in movements of the ankle or foot, making them irrelevant in the context of a toe raise. Understanding how each muscle group functions relative to specific movements is essential for effective exercise programming and training.
