Your blood pressure soared.

This change is almost immediate because your blood pressure is higher when you exercise than when you don't exercise. When you don't take any form of physical exercise, your blood vessels will adapt quickly. If you don't exercise for only two weeks, your blood pressure will rise several levels. Within a month of neglecting your body, your arteries and veins will harden, and your blood pressure reading will return to the level when you never leave the sofa or start exercising. If you have high blood pressure, going back to the gym for a month or two will lower your blood pressure and make your blood vessels work effectively.

2. Your muscles contract

Elite Daily reported that even if you haven't exercised for three days, your body will start to change. Your muscle mass will begin to decline, fiber will lose its ability to burn fat, and you will begin to lose the strength you have spent so long cultivating. You can't look in the mirror and see that your body is shrinking, but when you finally go to the gym again, your muscles will tire faster than before. Muscles that are rarely used in daily life, such as the abdomen, lose their tension the fastest, while muscles used for walking, such as hamstring, decline slowly.

Your bones are getting weaker and weaker.

One of the long-term effects is related to your bone health. Of course, you won't see this change in the mirror. But if you don't exercise for months, the effects will reach your bones within a year. "As we get older, as time goes by, we need to work harder to stay healthy," ShapeScale explained. "In the absence of weight-bearing activities, bones are more likely to become fragile and you are more likely to suffer from osteoporosis."

4. Your mood has changed

Everyone who is addicted to fitness knows the excitement after exercise. You will feel relaxed, healthy, clean and strong. Why? Explain that exercise can improve your mood and suppress the chemicals in your brain that cause depression by releasing other chemicals that relieve depression. Not only will you miss the excitement after exercise, but when you lose strength and start to gain weight, you are more likely to feel irritable and embarrassed about your appearance.

Your brain function has changed.

When you stop exercising for a period of time, your mood is not the only change. An article in Men's Magazine recorded a study by the University of Maryland, which examined the effects of stopping sweating on cognitive function. This study tested endurance athletes for 10 days, and the results showed that these athletes "reduced the blood flow in hippocampus and other memory-related areas of the brain." Of course, a few days' rest doesn't necessarily lead to complete amnesia. But this should be an extra motivation to start exercising again.
