thanks for the advice there guys, I already do one armed overhead press and I do feel that a bit in my 'core' i guess but I would like to isolate my obliques if I could. Overhead stuff I feel in my abs as well and I'd like to take them out of the movement.
I don't really understand what you mean about the shovel lifts, I like the name though.
I'm a long way away from ever looking like a bodybuilder, I know a lot of folk think bodybuilders shouldn't train their obliques or they'll look bulky, but that doesn't really apply to me, I'm a right skinny fuck.
My diet is alright I think, it's not perfect but it's pretty good.
And as for doing side bends correctly I only do them with one dumbell at a time, and yeah I've never really understood what that was all about when folk use 2 and just kind of rock sideways. It's pretty weird, anyway the dumbells in my gym go up to 40k and I can do loads of side bends with those and I'm not strong at all, those 40k dumbells are the heaviest I can press and I could only maybe manage them for 1 or 2. It's my grip that gets it more than anything else when I do sidebends.
Just want a movement that isolates the obliques but it sounds like it's hard as hell to isolate them!
