Nearly every strength and conditioning coach in the country relies on percentages to enforce desired intensities to athletes for certain lifts. Basically, the client would perform their lift at a percentage of their 1 repetition max. If they had a max bench press of 100lbs, and you wanted to do 3 sets of 12 reps at 60%, they would do 3x12 at 60lbs. This is absolutely necessary in most strength and conditioning environments for multiple reasons, including consistent program design as well as enforcement of intensity (speaking from experience, some people WILL slack if given the chance). So the question becomes, are percentages right for you?
Now that the columns you want reformatted to a different size have been chosen, it is time to do just that. Using your computer‘s mouse, right click anywhere within the highlighted area. This will bring up a pop-up menu. On that menu is the option ”column width”. Click on that option. This will bring up a window asking you to enter in the width of the columns. If there is a number already in that box you will need to erase that first by highlighting it and pressing your ”delete” key. Now type in the number ”12” and click the ”Ok” button.
