To be clear, my point was less about getting buff then staying flexible and having enough muscle to pause the aging process. Ask any CrossFit trainer: the reason people get old and start complaining is that they stop using basic muscles. Just watch older people trying to get in and out of chairs. Even squatting with no weight and just a broomstick will be fantastic for your overall health and sense of well-being and ability to ride a higher peg machine like the Busa. Nothing wrong with building muscle, though the CrossFit guys did convert me to the benefits of full range of motion.
