For those with health issues, regular exercise is not generally recommended.

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.

this is true. vitamins and minerals wounds heal and boost your immune system so you don’t get as sick.
