So you think that going to a gym is the best use of your money to get the best exercise that you need. Let’s do some calculations to figure out roughly what the cost would be in a year. You may extrapolate from these figures what you might spend. Assume that you will go 5 days a week and it is 5 miles from your house. A membership averaged out based on the part of the country you’re from will be roughly $40/month or $480/year. Your car gets 20 miles per gallon and traveling roundtrip makes a total of 10 miles a day. Going five days a week times 10 miles is 2600 miles a year divided by 20 miles per gallon times an average gas price of $3.50/gal. Equals $455.00. So in a year we have spent $480 in membership dues plus $455 in gas which equals $935.00 to use a gym. We are not talking about how much your time is worth but you might add it into your equation.
