body position for lat pulldowns

[toneloc85]

was wondering what difference you place your body at(straight up,laying back) is better. also i see guys at the gym when laying back moving their body up with the weight then back down with each rep is this bad form?

Im interested in this one as well. Cause I see both forms on veteran and novice users.

Do pull-ups instead. You'll grow faster. Keep your body straight and flare your lats as you contract.

yes pull ups are a staple in my back routine but also use pulldowns towards the end of workout.any info on the proper form or if they are both good but for different parts of the back?

if you are advanced enough start doing pull ups no matter how much weight u use with pull downs pull ups will always be better espacially if u do it weighted!

ok so pull ups are great, but anyone have on comment on wether keeping a straight back or moving up to laying back with each rep is correct because like CEELO i have witnessed both advanced and novice people using both of these forms.
