I agree with Mael...for mass do about 6-8 reps...3 sets for each form.
Make sure you give more time between sets, to breathe & rest. (about 1-2 min.)
This is not about burning calories...but building...you need breathers.

I know you are going for more weight...but at the same time be sensible.
Make sure you can do the form correctly & smoothly.
(both push/pull & return)...this is MORE important than weight.

Try for full range of motion (all the way up, all the way down)
Do not lock your arms.

Do not jerk or go fast. Control is necessary at ALL times.

Make sure you are breathing out during the push/pull,
and breathing in during the return.

**These are the basics of weight-training.

Now, if you are getting used to doing it...you are advancing.
Try for a bit more weight...but do it safely
And maybe try to hesitate & hold for a split-second at the end of the push/pull (this is a bit more advanced)
