I strictly use DBs for all of my pressing movements. I have a bum shoulder and barbells aren't something I can use anymore. I've always looked at it like this. Barbells build a solid ego, dumbells build a solid body. I know that's not really the case, but barbell bench is more for show and bragging rights for a lot of new gym rats and egomaniacs. I've been personal training for years (not bragging, just showing some credentials) and I feel that dumbbell bench is a much more thorough workout than barbell because of control and isolation. BOTH have their places and BOTH are amazing workouts. But like all of you guys, I always get asked "how much do you bench"? To which my answer is always, "I don't know". I really don't.
What I'm blabbering on about is this. You don't need a bunch of equipment to have a good workout routine. Dumbbells are an essential. No equipment is a waste. You sometimes have to adjust your routine to what is available to you and you can have great results.

Guys, I know I talk too much, lol.
