Regular exercise will help improve cardiovascular health, reduce blood pressure and increase blood circulation. Exercise also helps control weight, promote metabolism, burn more calories, prevent obesity and chronic diseases such as diabetes and high blood pressure, according to the health website Medical News Today (UK).

When you stop exercising for a long time, the body will experience the following adverse effects:

Muscle loss and decreased strength

When you stop exercising, within just a few weeks, your muscles will lose their optimal shape. Both muscle mass and tone will decrease. As a result, your muscles will weaken in terms of performance, leading to a loss of strength and endurance. Over time, activities that were once easy for you, such as climbing stairs or carrying heavy objects, will become more difficult to perform.

Weight gain

Without regular physical activity, the body's metabolism slows down. The ability to burn calories decreases. As a result, the body accumulates excess fat and causes weight gain. Excess fat accumulated around the abdomen increases the risk of high blood pressure and diabetes.

Poor cardiovascular health

Not exercising regularly also affects the cardiovascular system. The heart pumps blood less efficiently, leading to reduced endurance and a higher resting heart rate. Over time, this condition increases the risk of heart disease, stroke, and other cardiovascular problems.

Decreased bone density

Regular strength training such as weight lifting, push-ups, squats, and pull-ups will maintain bone density and keep bones strong. On the other hand, skipping exercise will cause bone density to decrease and bones to become more susceptible to fractures. This is especially true for older adults.

Reduced immune function

Regular exercise boosts immunity by stimulating blood circulation, which helps immune cells move efficiently throughout the body. When you stop exercising, the opposite effect occurs, causing your immune system to weaken, making you more susceptible to common infections like colds and skin infections, according to Medical News Today .
