I hope you make a tutorial how to do bodybuilding poses with some explanation and no music, because your body is insane mann!! btw im your fans now and good luck mannn:)
You use the same technique as big Jay Cutler on the incline dumbbell press. Focus on the stretch at the bottom instead of the peak contraction at the top. It's pretty clear from research right now that the stretch is the most important part of the movement. Well done.
