I borrowed my brother-in-law’s treadmill and have been using it for exercise since winter started slapping us around. Honestly, I don’t enjoy walking on the treadmill or any other form of forced exercise.
I recognize the value but don’t enjoy the practice.
Some people really enjoy exercising. They are, in fact, effusive about it. These are not normal people. Such people should be studied, perhaps locked away in rooms far removed from the rest of us.
