"You mentioned, in your Canadian seminar, the bit about one-armed exercises being inferior to growth. However, I noticed you doing SOME one-arm exercises years ago. It appeared you were doing them in, let’s say, a "negative" style; controlling the lowering with slow, concentrated effort. Am I right and did you get results from this?"
Vince: "One-arms stink unless you are genetically superior! Serge Nubret just does one-arm DB curls for biceps and that’s all! Almost a concentration curl. He doesn’t need anything else. When he shows a preacher curl in a seminar – that’s just for the troops to show them HOW it is done."
