He is utterly useless in 2h+ hikes with 1000m+ elevation gains. Kind of a false equivalence. Firstly, I'm not sure that long, arduous hikes are very relatable to e.g. moving around in old age, whereas doing a single squat is absolutely comparable to getting out of a chair for anyone. Secondly, my guess is that you'd be utterly useless if you had to carry a pack whose weight equalised the difference between your respective bodyweights.
