In a nutshell, DC is basically doing some warmups and then one all out Rest Pause set per exercise. But if you want full details, hit up google.
My split, it's pretty damn ridiculous, or at least is far from traditional and it's probably not what you are looking for.
You can look up a Yates 3 way split...Something like Chest and Biceps, Legs, Off, Delts, Back, Off, repeat, or do all 3 workouts, take a day off repeat etc. Follow a heavy light approach, going heavy all the time with little rest can burn you out quick. It's not that hard though to structure a good routine and stick with it, if it isn't working out, you can always change things up, if you never try it, you'll never know if it will work better or worse than your current program, that's why I am game for trying new things out in training and after trial and error you can figure out what program will work best for you. And listen to that ex-bodybuilders advice if you see him as an adavanced trainee/trainer.
