Your target heart rate should be between 75-85% of your max heart rate. To find your max heart rate you take 220 and subtract your age from it to get your max heart rate. Then you can find your target heart rate easily by taking a calculator, typing in your max heart rate, and then type in "subtract (-) 15%". Record that number on a piece of paper of some sort. Then retype your max heart rate and then type in "subtract(-) 25%". Also record that number down on the same piece of paper you wrote the original number on and put a dash (-) between the numbers. This will show you the two numbers your target heart rate should be in-between.
