Some good info in this thread. I believe that even an overload of 105% of your one rep max, would be enough to elicit true negative training. Trying to go 140% more then your used to is suicide i m o lol. I think on a limited bassis this can be benifical.
As far as spot traing for growth, i do belive its 100% posible. Why do curls and such for arms if it wasnt?
I find people who follow the squat deadlift bench type of system, get stronger and a powerlifter look,"cough cough fat" looking.
I will tell you again. No matter what anyone tells me, or you, DIRECT STIMULATION OF A MUSCLE GROUP is absolutly necesary.
Now do i think thats the best way to train? Of course not.
Multi joint compound moves first, isolation moves next.
Im realy looking forward to seeing your progress man.
