Components of internal training includes stance training , stretching and strengthening of muscles, as well as on empty hand and weapon forms which can contain quite demanding coordination from posture to posture. Many internal styles have basic two-person training, such as pushing hands. A prominent characteristic of internal styles is that the forms are generally performed at a slow pace. This is thought to improve coordination and balance by increasing the work load, and to require the student to pay minute attention to their whole body and its weight as they perform a technique.
