You put it so correctly!
We see so many people exaggerting just to show off. Just visit a gym when a bunch of macho men are training, to me it's just too much energy wasted to wear your body off. Moderation is everything and always adjust your training programme to your body's needs and capabilities. That way you gain physical and mental well-being. It's like my Greek ancestors said: A healthy mind in a healthy body (Νους υγιης εν σωματι υγιη)
