I do some training on and off, sometimes it goes on for months. Never in the gym however.
I'm fairly active otherwise I do exercises every day just to make all of my muscles move, I like to take walks, and go on hikes, I live near to the woods. While I walk, most of the time I do various stuff, like breathing exercises, or posture fixing ones.

I do agree, everyone should do something. Our societies do very little to their health, and we focus way less on physical training in schools, and we miss the opportunity to give the new generations a healthier lifestyle.
