Okay buddy let me just tell you...
calisthenics do not work for mass. It doesn't matter what you do because nobody on this whole board has put as much work into calisthenics as I have.
I've been working out hard/serious for about 8 years now, and because of my line of work I only had gym access for about half of it, sometimes would go 6+ months without gym.
I am very good at calisthenics, I know everybody else's routines like the back of my hand and I've basically done all of them, plus my own experiments by the assload, and NONE of them will get you big. Doesn't matter if you do it weighted, unweighted, high rep, low rep, high intensity moves, low intensity for a lot of volume, some mix of all of the above.
Doesn't matter your diet, doesn't matter unless you take steroids.
At best you can maintain strength/endurance but you will never look like more than an overdeveloped teenager on calisthenics.
Anyone who is all ripped to shreds on calisthenics, including that green faggot Frank Medrano, they are DEFINITELY on gear. 100%. No question at all in my mind.
I mean stop and think about what it must be like to try to cut and get ripped while doing calisthenics - as you cut you get lighter, and the calisthenics moves get EASIER, leading to less muscle mass. Being lean and muscular at the same time on calisthenics doesn't make sense worth a fuck unless you are frauding hard.
The ONLY person in the calisthenics world who MIGHT be natty is D300, because that nigga is puffy as fuck and only looks buff because he does this shit for high volume at 300 pounds.
Just go to the gym if you're able. If you want to do muscle ups and shit, work on them as a skill, but just lift dude. Seriously. Listen to your elders.
