The tibialis anterior muscle is located on the front of your lower leg, right next to the shinbone. It's primary function is dorsiflexion, lifting the foot upwards towards the shin. It also helps with inversion, turning the sole of the foot inwards. Think of it as the muscle that prevents you from tripping when you walk. It's vital for walking, running, and generally moving without looking like a clumsy oaf. Strengthening it can improve balance and prevent shin splints.
