slant bench or flat bench?
 

im just wondering which one is more effective for incline dumbbell press?

I see people do one or the other. IS there any differences in working different muscles?

Or just depend on each person's preference?

there are two types of "slant" benches... incline or decline..

I don't know what u realy mean by a flat incline... its an oxymoron... if its on an incline how can it be flat?

But if you were to ask me what is better flat dumbell or incline dumbell, i'll tell you to do both... it works out a different part of the pec's so doing them both will benefit you...

Incline makes the top of your chest come out giving it a full look.

Flat bench works the full Chest at once.

Decline works the lower portion giving the shelf look on your pecs.

I like to change up what I start with each week. That way I'm not always fatigued when I get to a certain portion of the chest and not being able to work it as hard as if it were fresh.

Berz out.

what berz said, they each act on a differnt section of the chest

it's best to do them all if you can

i do incline dumbells at 30* and if i dont have a spotter for flat barbell i do em in the smith machine and ill even have the bench at about 10* for that too.

u make no sense... your asking "incline dumbell press" is better on either "flat or slant" ?

if you want to do "incline" dumbell press, well you do it on an "incline" slant bench. please go with a friend (that knows what their doing) or get a trainer for your first few times before you hurt yourself so you know what exactly your doing.

I see too many people doing things all wrong, either setting themselves out for injuries in the near future, or just wasting 1-2 hrs at the gym doing exercises improperly, resulting in slow gains (and also wasting everyone else's time while they hold up the machines)
