I found the topic of exercise addiction to be interesting. I didn't even know that it was a thing. I have heard people say that they are addicted to exercise and working out but didn't realize it is recognized in the psychological community. I would say that I like to exercise myself and it makes me feel good but it doesn't give me the high some people get from it. Exercise addiction follows drug addiction in a few ways. One difference is that exercise addiction is a positive addiction, meaning that it benefits health. it can turn into a negative addiction if it gets too extreme.
You often don't think that exercise can be harmful to your health. When you exercise, you are building muscle and improving your tolerance to it. This is like drug tolerance where the user needs to increase the amount of drugs they take to achieve the high they want. People with exercise addiction will start to need to exercise more and more. This can be harmful to the health because if you work out too hard, too fast, you can cause harmful affects to your body. This is one of the rare addictions that can improve your health but can also become harmful and addictive.
