This may sound a little unfair. After all, a standard Microsoft installation would include something called Equation Editor. Suffice to say, it wasn‘t advertised in the promotional videos. Software like Matlab was considered vastly superior and had the added advantage that you could analyze the equations as well. Anyway, the good news is that Microsoft has taken a big step forwards with Office 2010 and it‘s now possible to correctly display formulas in a pretty painless fashion. In Excel 2010, you should select the Insert ribbon, and click Equation. This creates a textbox and brings up a whole new ribbon with options for inserting equations. As well as providing easy access to the main Greek symbols, Microsoft have provided quick access to a number of simple functions, such as fractions and exponentials.
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?
