In recent years, I have added yoga to my "body list." For the uninitiated, it likely sounds foreign, but the strength, flexibility and mind-centering aspects of a yoga practice must be experienced to be fully appreciated.
"Sounded?" That word suggests that they have only read or heard about it, without actually trying it.
I wonder if they would consider the physical and mental development required to hold Mayurasana as soft?
Sarcasm aside, lifting is far more effective than anything else for building strength.
