Explain the importance of safety measures

obesity is a result of eating unhealthy junk food which increases the fat content of the body and makes you obess. it is also further because of not doing proper exercise and not participating in any physical activity.

the more fit you are, the faster the recovery. your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute—a drop of less than 12 beats a minute is considered abnormal. this “recovery heart rate” is measured as part of an exercise stress test.
