Can push-ups be used to develop stamina? For instance, could a trainee use them like running for the lower body, like doing push-ups for an hour without rest?
The physical workers that work all day round with their hands, such as blacksmiths, are known for their strong hands. They also have high stamina in their upper bodies. I'd probably be exhausted after 10 minutes if I did what they do. I get tired quickly when carrying something heavy in my hands, yet I've seen tradeswomen carrying about 20kg in each hand for kilometers. So my hands definitely require strengthening.
So would it be a good idea to do as many push-ups as possible to develop upper-body stamina? I can't imagine doing 1000 push ups at the moment, but many people don't imagine even fast walking for over an hour.
