This seems simply, the answer is yes. But I gain strength in my right bicep and tricept faster than the left. My left side holds me back from increasing weight faster. I could technically lift like 10/15/20 or more in my sets with my right, while I can't get my left above 8/10/15.

But I'm guessing I should take my time and make my gains at the same time vs possibly looking like arnold and his mini-me in the same body, yes?

Right! One of the objectives of using dumbbells is to promote symmetry! Both for aesthetic reasons and health. If one side is stronger, it will lead to all sorts of postural problems. Lift for your weaker side and get that up to the strength of the other side before you move on.

Maybe like arnold and danny devito in twins

Good question. I am left handed and my right side always holds me back.

Thanks for the good answer mel.

That is a good thing about training with dumbells or cables. Most of us favor one arm with machine or even barbell lifts, and may not even notice it.

Even at my current bodyfat levels I can measure a 0.5" difference in my biceps measurements and see a difference in my right vs. left trap. The thinner we get the more noticeable assymetries wil be.

My left hand has about a 10% lower gripping strength (as measured on a dynomometer), but there isn't a visible difference in my forearms.

Maybe Mel will correct me if I'm off base here but ... I saw a ditty on a local news programme about personal trainers ... one of the things they spoke about was having someone to help you with this sort of thing. I think the 'focus' lady of the piece had been sick and wanted to regain muscle strength. The trainer found the right/left discrepancy and helped her fix it.

I spoke to my new chiropractor and he's working between my shoulder blades ... so far that feels better too.
