Your arm weighs 5.3% of your total body weight

So, that means the arm of a 150 pound persons weighs close to 8 pounds. Picture an 8 pound brick on top of your bow. Now place the middle of the bow on the string and press the stick to the hair using only your first two right hand fingers. Makes a good case for where to get your bow pressure, right? (Once again reminding us that less is more.)
