Bowling is a sport in which players attempt to score points by rolling a bowling ball along a flat surface, usually a wooden or synthetic surface, into a formation of pins. There are many forms of bowling, with one of the most recent being ten-pin bowling. Bowlers have a high injury rate in the shoulders, knees, hips, elbows and wrists. You can reduce your injury potential by paying close attention to these areas in your conditioning program. Upper body power is required to propel the ball down the lane.
