Knowing when to stop?

I never do 3 exercises for biceps but than again I'm not a bodybuilder. Your biceps are only a 1/3 of your arm so make sure you're really hitting your triceps. And of course more isn't better.

Here's something to think about. Deadlift more and guess what.... your biceps will grow.

Agreed 100%

3 set of hard work (squeeze / flex your bi at the top of the movement) will exhaust your bi
