HOW HARD?
How hard you workout is also determined by your goals. If you use your Horizon Fitness recumbent
bike to prepare for a 5K race, you will probably work out at a higher intensity than if your goal is gen-
eral fitness. Regardless of your long term goals, always begin an exercise program at low intensity.
Aerobic exercise does not have to be painful to be beneficial! There are two ways to measure your
exercise intensity. The first is by monitoring your heart rate (see page 17), and the second is by eval-
uating your perceived exertion level (this is simpler than it sounds!). Note: Always consult your physi-
cian before beginning an exercise program.
PERCEIVED EXERTION LEVEL
The second and simpler way to gauge your exercise intensity is to evaluate your perceived exertion
level. While exercising if you are too winded to maintain a conversation without gasping, you are
working out too hard. A good rule of thumb is to work to the point of exhilaration, not exhaustion. If
you cannot catch your breath, it’s time to slow down. Always be aware of other warning signs of
overexertion.
