FST-7, Dennis James' super slow training (God knows what its called), German Volume, Occlusion training, Dogshit training or whatever its called, supersets, giant sets, Milos magic drink blood flow training bollocks,
strip away all the nonsense, basics have always worked and always will.
Lift heavy (Relative) in good form, to good muscle failure, progress by getting stronger in that rep range, increase weight, get out and rest FFS (overtraining undertraining etc just rest sensibly! not rocket science!) EAT WELL...Go again.
Anything on top of that is reinventing something that has never needed reinventing.
