Full context:   In modern form, the archer stands erect, forming a "T". The archer's lower trapezius muscles are used to pull the arrow to the anchor point. Some modern recurve bows are equipped with a mechanical device, called a clicker, which produces a clicking sound when the archer reaches the correct draw length. Traditional English Longbow shooters step "into the bow", exerting force with both the bow arm and the string hand arm simultaneously, especially when using bows having draw weights from 45 kg (99 lb) to over 80 kg (180 lb). Heavily stacked traditional bows (recurves, long bows, and the like) are released immediately upon reaching full draw at maximum weight, whereas compound bows reach their maximum weight around the last 4 cm (1.6 in), dropping holding weight significantly at full draw. Compound bows are often held at full draw for a short time to achieve maximum accuracy.
