Speaking of mass monster. Looked more into it and one of the top God’s of calisthenics trainings on line is 511 to 6 foot and clocks in at under 170 with sub par leg mass.
But let’s be honest your not going to many guys over 200 plus doing all those circus tricks you see. Since the added mass is a disadvantage.
People assume that all of these guys aren’t doing some other form of resistance training.
But let’s be honest if BW exercise were truly the only optimal way of building size and strength . No one would would be doing any other form of resistance training.
