Okay so I've been doing a lot of reading in the forum and it's basically confirmed that doing basic barbell exercises builds strength. If I could just get a barbell and do stuff with it I wouldn't even be making this thread, but unfortunately I do not have anywhere near the required real estate to be able to own an operate a barbell. Yes, it's that cramped in here. The only thing I could actually do besides basic calisthenics would be to get some dumbbells and do some finger grip pullups. It'll also be a while before I can just go to a gym and just lift, bench, and squat my way into power. This leads to the thread title. Is it possible to gain strength with just dumbbells? Specifically, is it possible to get similar results with a dumbbell as you can with a barbell? Granted there's going to be the time factor against them since you can put a lot more weight on a bar and have balance and stability support that weight instead of it being mostly just your arms individually, but if it is at all possible I'd like to at least try.
