Detraining: What Happens When You Stop Working Out

Written by Austin Moy | Mar 23, 2023 12:00:00 PM

We all know that working out is essential for maintaining our physical and mental health. But, sometimes life happens, and we need to take a break from our exercise routines. Whether it’s due to an injury, illness, or simply a lack of motivation, taking a break from exercise can have consequences. This is known as detraining, and in this post, we’ll explore what happens to your body and fitness level when you stop working out.

Loss of Muscle Strength and Endurance

One of the most significant consequences of detraining is the loss of muscle strength and endurance. When you stop working out, your muscles are no longer being challenged, causing them to lose the strength and endurance gained from your workout routine. Studies have shown that after just two weeks of detraining, significant losses in muscle strength and endurance can occur. This means that if you take a break from working out for an extended period, you will need to start from scratch when you decide to return to your routine.

Decreased Cardiovascular Fitness

In addition to losing muscle strength and endurance, detraining can also lead to a decrease in cardiovascular fitness. Cardiovascular fitness refers to your body's ability to efficiently transport oxygen to your muscles during exercise. Regular exercise helps to improve this ability, but when you stop working out, your cardiovascular fitness levels can decrease rapidly. Studies have shown that after just four weeks of detraining, significant decreases in cardiovascular fitness can occur.

Changes in Body Composition

Detraining can also lead to changes in your body composition. Regular exercise helps to build and maintain muscle mass while reducing body fat. When you stop working out, your body will begin to lose muscle mass and gain body fat, leading to changes in your body composition. This can result in a slower metabolism and an increased risk of chronic diseases such as obesity and type 2 diabetes.

Mental Health Impact

Detraining can also have a significant impact on your mental health. Exercise has been shown to improve mood and reduce symptoms of anxiety and depression. When you stop working out, you may experience a decrease in these benefits. This can lead to feelings of sadness, anxiety, and irritability.

Sleep Quality

Regular exercise has been shown to improve sleep quality. When you stop working out, you may experience a decrease in the quality of your sleep. This can lead to feelings of fatigue and a lack of energy.

Detraining is a natural part of life, and there are times when we need to take a break from our exercise routines. However, it’s essential to understand the consequences of detraining and how it can affect our overall health and fitness levels. If you need to take a break from working out, try to maintain some level of physical activity, such as walking or yoga, to help minimize the effects of detraining. Remember, consistency is key when it comes to maintaining a healthy lifestyle.
