Weight / Fat loss

Dumbells are your friend. Not only far better for engaging all the smaller stabilising muscles in the bench press and allowing your hands to rotate through the pressing motion you can also max out without ending up getting crushed under a barbell.

Setting up for dumbell press on a bench is a bit of a faff with bigger weights though - also a bit of a pain if you're doing a hypertrophy routine and want to include reps to failure/include negatives.

Neither is better, just different.
