punch in which the arm is
whipped sideways from the shoulder joint with
minimal elbow bend. The name is derived from the motion, which mimics the action of manually cutting hay by swinging a scythe. The most frequent and effective cause of a one-punch knockout or kill. Since a haymaker's power is derived from
weight transfer and momentum instead of muscle contraction, a
long windup is required to generate sufficient force. Haymakers are frequently used from a mounted position in mixed martial arts as part of the "ground and pound" method, as the legs cannot be used to generate power. These punches pack power, but leave the person vulnerable to a counter punch during the wind up or if the haymaker misses generally when both combatants are standing.
