We can see in some museums of history the weapons which men used in warfare even 150 yrs back are so big and heavy that now a normal man can only dare to lift.. Maybe humans are one of the rarest creatures facing problems of obesity, and have to do heavy workouts to build up, whereas animals are naturally born strong..

By evolution? No. There is not nearly the influence on the human species to increase our strength potential these days due to the lack of a need to run down our own food, the availability of machines, etc. but there are also no diadvantages from a reporductive point of view to being strong. If the average person was trained from a young age today to be able to do the same things a caveman did a few thousand years ago, they would be able to. We have the same potential for strength from a genetic standpoint as we did millenia ago, since weakness isn't an advantage. The only difference is we are not becoming stronger or weaker as a species, as mental facility in western countries is more strongly selected for than phisical strength.

The same museums contain suits of armour which were made for the big and well fed elite caucasians of their time. Few of them could contain a caucasian of average height today, obese or slim.
People are growing taller, and have the potential to be stronger than their forebears, but this is seldom achieved, due to the sedentary existence (relatively speaking) permitted by modern living.
Heavy workouts are therefore only a substitute for ordinary past living. Evolution is not making humans physically weaker.
The average current man enjoys a likelihood of being of greater stature than his ancestors, and any physical weakness is not due to some diminishing intrinsic factor, driven by evolution, but to day to day non-use and development of physique.

> Are humans getting physically weaker by evolution?
Nope. Strong men (and women) have children.
Using heavy war-axes and hammers properly takes a lot of practice. I'd bet that if people these days trained for years to use those kinds of weapons, they'd do just as well as the medievals.

They're are some examples that may show possible reason to believe that the human body on average is shrinking, but in acctuallity, over the last few centries the average size of people has been growing.

One reason no person looks to have suggested so a procedures is the commerce-off between capability and dexterity. specific a ninety pound woman chimp has greater arm capability than Arnold Schwartzenegger in his top, yet attempt to get the chimp to throw a spear, or style complicated strategies.

Evolution isn't going to happen that quickly unless people are dying because they are too strong. That just isn't happening.
People are just getting lazier.
