I do it, I go to the Gym 3 times a week and I do strength training at home and some yoga and I walk most days. I have never in my life gotten a mood boost or hid of endorphins from exercise. I do it to stay fit and to not gain weight and other health benefits but to me the exercise is for the most part a chore I just have to do. I don't enjoy watching sport or playing team sports, I'm not competitive in the least all my hobbies are creative and somewhat sedentary.
Anyone else like this?
