The following two examples compare calculations of the 220- and 180-Formulas.
| Example 1: A 35-year old sedentary overfat person beginning an exercise program. |
| 220-Formula |
| 220−35 × 60−85% = exercise HR range of 111–157 |
| 180-Formula |
| 180−35, then |
| category (b) (−5) = 140; exercise HR range of 130–140 |
| Example 2: A 35-year old healthy competitive athlete. |
| 220-Formula |
| 220−35 × 60−85% = exercise HR range of 111–157 |
| 180-Formula |
| 180−35, then |
| category (d) (+ 5) = 150; exercise HR range of 140–150 |
