Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Lie on your back on a flat bench with your head hanging off the edge. Place a small weight plate or resistance band across your forehead. Keep your shoulders relaxed and your body stable throughout the exercise. Slowly curl your chin towards your chest by flexing your neck. Pause briefly at the top of the movement, ensuring full contraction of the neck muscles. Slowly return to the starting position with control, avoiding any sudden movements. Repeat for the desired number of repetitions.
With how heavy most weight plates can be, directly resting one on your forehead can be quite uncomfortable. Placing a cloth (or some sort of hat) along the forehead can act as a cushion and greatly enhance the comfortability of the exercise.
