i'm trying to work out why leo costa is in there?
are you leo funk?
if you are, that's cool. he had a great physique. got busted for some roid distribution rap back in the 90's, but had some very good ideas re training.
he learnt some things from the bulgarian sytem and tried to apply it to bbing ie 'serious growth' principles.
it was innovative, insightful and somewhat revolutionary considering that, with yates bringing hit well and truly back into the spotlight, 'serious growth' went completely in the other direction ie 6 days pw, 3 times per day, etc and costa had the physique to back his talk which is always refreshing. i actually tried it and made great gains naturally. only problem was that i ended not having time and motivation (stuffed from all the training) to do all the training sports specific training that i was supposed to be doing.
Some guys have pointed out that, the East block and Soviets, hand picked only the Most Genetic superior to train.
That the average guy has little chance of holding up to that volume and intensity.
I tried 6 days wk in my 20s and it quickly became overkill. And, I was practically indestructible then.
