If it has been a long time since you’ve gotten up from the couch from binge-watching “Breaking Bad” on Netflix, then you might find it harder than you think to get back into the routine. This is what happens to your body when you substitute working out with being lazy.
First of all, your blood pressure skyrockets. Almost instantly your blood pressure is higher on days that you don’t work out versus days that you do. Your blood will adapt to a sedentary lifestyle after two weeks, which increases your blood pressure immensely. You know what also goes up, your blood sugar. Your blood sugar rises after you eat, then drops once your muscles and tissues absorb the sugars for energy. After a week of lazying around, your post-meal blood sugars remain elevated and can raise your risk of heart disease and diabetes.
You’ll get winded a lot faster. When you’ve walked up the stairs and stopped for a breather at the top, it usually hits you that you’ve been away from the gym for a while. Within two weeks of avoiding the gym, the amount of oxygen that your muscles can use decreases as much as 20 percent! You lose mitochondria, an area in your muscle cells that convert oxygen into energy.
Your muscles eventually disappear. Strength lingers a lot longer than endurance once you stop training. Your quads and biceps could shrink sooner rather than later. Significant declines in muscle mass could be as soon as two weeks, and recovering those muscles would take a lot more time to gain that the time it took to lose.
You plump up. Within a week of not going to the gym, your muscles lose their fat burning potential and your metabolism slows right down. The longer you spend away from the gym, the bigger you’ll get.
