What happens if you don't get enough exercise?

Answer 1

You get flabby and weak.

Aside: Exercise is not just a formal exercise program (weight lifting, yoga, running, etc.) it can include an active lifestyle like a postman (walking), stevedore (lifting), mothring (cleaning, cooking, lifting children)

Answer 2

Little or nothing. The resting values stay the same.
What you will effect is total blood volume (it goes down) and the maximum capability of the heart.
The body is constantly (but slowly) adapting to whatever stresses you subject it to,
go out into space (or any low gravity situation - including lying in bed) and you turn into a flabby weakling.

Answer 3

you die.

I had to go to physical therapy for a pulled muscle, the therapist said i wasn't breathing during the excercises (kind of holding breathe and counting i guess) The therapist stated that this can ..... increase your blood pressure.

Answer 4

You become at risk of being overweight, your muscles don't develop making you more prone to injury, your energy levels are lower, you are more prone to sickness and disease.
