Just wondering how fast you guys perform your repetitions, specifically when you looking to maximise hypertrophy/mass gain? (I.e. How much time is spend on the positive, negative, and also the contraction in each rep.)

I'm currently spending about 1-2 seconds on the positive, 0.5-1 second on the contraction, and about 3 secs lowering the weight for most exercises.

I'd like to know what sort of speed the rest of you guys use, and why?

Cheers y'all!
