Once you're in space, you can simulate any gravity you like.
In relation to Proxima, no matter what kind of planet it is, humans won't be able to live there unaided, or indeed on any other planet, because we only evolved for this one. So its either a future of artificial habitats (and if you're doing that, then the reasons for colonising planets at all get a bit shaky; cheap radiation shielding is about the only reason because resource extraction will be cheaper and more efficient in space), or, we engineer ourselves for the planets we find.
Back in the golden age of Sci-Fi the likes of Larry Niven postulated spindly humans evolved for living on low gravity worlds like WeMadeIt and squat, tank like high grav Jinxians, but he worked on the assumption that we would evolve for these environments. I doubt we could do that quickly enough without the conditions causing serious issues (imagine low grav babies evolving in wombs designed for 1g, or what high grav would do for your blood circulation), so genetic engineering becomes the obvious solution. By the time we got out there, we probably be doing it to ourselves for other reasons anyway.
