This is the number you would hit if you were trying to work out at 100% of your capacity. But you don’t want to work out at 100% of your capacity. It doesn’t do anything for you.
You want to work out at somewhere between 60-75% of your total capacity. You learned how to calculate percentages in high school. Since that was a little while ago for some of you let’s review how to do it:
To find 60% of 150: 150
x .6
90 = beats per minute
To find 75% of 150: 150
x .75
112.5 = beats per minute
So you would want to stay in a heart rate range between 90-113 beats per minute. Now that you have the formula, you can calculate your range no matter what you age is. Remember that the example above is for someone who is 70 years old. If you are older or younger you will have to redo the math to get an accurate number.
