I agree and disagree with all of you. As time goes on new training methods will prevail over other ones. I think now days it is good to have both principles. I think every body part you should start off with 1 or 2 core lifts and lift heavy. And for the other exercises for that body part try to focus on using the muscle with good form. I think everyone should incorporate both methods. And another thing is everyone is different. There are a lot of different body types out there. What makes my chest grow wont make your chest grow the same. Everyone is different. Also respect the pro's man. They bust their ass 24/7 365! Look at them...... Who wouldnt want to look like ronnie or jay?
