HOW HARD?
How hard you workout is also determined by your goals. If you use your Horizon
Fitness Elliptical Trainer to prepare for a 5K run, you will probably work out at a
higher intensity than if your goal is general 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 exer-
cise intensity. The first is by monitoring your heart rate (see page 27), and the sec-
ond is by evaluating your perceived exertion level (this is simpler than it sounds!).
Note: Always consult your physician 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 con-
versation 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 overex-
ertion.
