 When wearing focus mitts it is important not merely to hold them but to actively "feed" them into the punches, to balance their force and prevent injury to both parties.Similar to a focus mitt but designed for different purposes are heavier Thai pads used in muay Thai boxing and MMA, kicking shields, body shields and uppercut shields used in a variety of martial arts to help gauge distance and practice techniques with kicks, knees, elbows and uppercuts.It is often said that holding focus mitts can be as taxing as striking them.
