You're supposed to lean back to some degreee. That's what hits the lats. Do you think you are hitting the muscle effectively with your neck all shrugged like that? You need to relax that neck and feel the lat pulling the weight. If you don't lean back, it becomes a shoulder exercise.
That's okay..that's how the old ladies in the gym do it too, rookie!
And how would know if you were stronger than me?
If I beat you, you'll just make 5,000 post claiming you're the winner anyway, you whining bitch (making everyone sick of you in the process)
And, you make up some funky rules by some weird formula, why you really did win even though I lifted more weight.
Then, you'll say you are a lifetime natural and I'm not (even though I am).
Your last bitch-ass excuse would be there is no one at your age who can lift as much as you.
Did I leave anything out?
