Why is it necessary to do 500 dips and 250 pullups in one day? What was their logic behind that?
You do em explosively. I was a brawler and it gets you used to throwing around your weight. In addition it added hardness to the body as resistance against body punching.
It also got me strong. They told me to quit lifting and do calisthenics, so instead i did both
my lifts all around shot up. I still do it like that today and am benching 305x4, BB row 305x4, weighted pullups +155 @ 172lbs.
When you do em often, as your muscles get harder, it gets very easy. At the time I was busting out 60-100 pushups each set. 50-70 dips each set. 20-40 pullups each set. So it only took like 5 or so sets to finish each exercise
It also helps mentally. Doing that many in one set is BORING. But it teaches you to have the will to push on even through pressure (when your muscles are burning and mind is screaming to stop).
