Not necessarily. Three-and-a-half years ago (March 2017), I massed 140kg;
today I mass 85kg. I have no doubt that in Traveller terms, both my STR and
END, both then and now, were below 7 _at best_, and I was hardly "fit" then
- or now. I might tire more easily on a world with 1.63G (which would make
my current weight equivalent to a mass of 140kg in a 1G field), but I have
no doubt that I could engage in normal activities - because I _did_, for
quite a few years. (Some of you who are regulars at TravellerCON/USA and
know me probably saw the difference - it was pretty marked, even at TCUSA
2017)

I'd expect that the lower limit for problems for an unmodified human would
be at _or_above_ 2G. I expect that NASA has some research done on this...

To be pedantic, neither mass nor weight are the problem; it's _inertia_.
