Phasic muscles are action muscles and use force when needed. Tonic muscles are slow twitch, meaning they can stay “on” for long periods of time.

The pre-movement muscles should be the muscles that are closer to bones, as they are stabilizers. Pre-movement is a task sorted out by the cerebellum in the brain in response to input from… Continue reading Pre-Movement

We can have impingements in our fascia from scar tissue, body history, daily activities, and stress. When… Continue reading What is Fascia?
