1. Bodies are a creature of habit. The more you exercise, the more your body learns to burn fat rather than store it.
2. If you had every single muscle in your body working together at the same time, you could lift about 50 000 pounds.
3. If you are not a regular exerciser, by the time you are 65 you may experience as much as an 80% decrease in your muscle strength.
4. Between birth and old age you will walk about 70 000 miles.
5. It takes only about 23 seconds for blood to circulate throughout your entire body.
6. If you are 25 pounds overweight, you have nearly 5000 extra miles of blood vessels through which your heart must pump blood.
7. People who cross-train with a variety of exercises are more fit and less prone to injury than those who do only one or two types of exercises.
8. Your heart is the strongest muscle in your body and beats about 100 000 times a day in the average adult.
9. The best way to judge whether you are exercising at too high of an intensity is to do the “talk-test”. See if you can carry on a conversation. If you can’t, you may want to bring down the intensity a bit.
10. Aerobic exercise is one of the best preventable medicines available and one of the cheapest.
