People live and die by their barbell bench press numbers it seems. I never got much out of it- probably because I have relatively long arms and so am mechanically disadvantaged. I hit 285 and that was enough. So yeah, I'm thrown out of the GetBig club, lol
But for chest development, which I am after, the use of dumbbells gives far better pectoral development. Most likely because I can turn my wrists and place my elbows in a position that feels far more natural. I never get injured using DBs because all that balancing required, plus being able to actually get the dbs in position, tends to limit the weight I use.
