Our body is mostly water (a fluid), and most of what is left is some form of solid (bones, ...).
Fluids and Solids are for all intensive purposes, incompressible, only gasses gas be compressed to any reaonable degree.
So when the atmosphere squeezes in on us, our bodies just push right back causing the net force to be zero, thus no accelertion, no crushing.

Pressure is all relative and the pressure of the atmosphere is equaled by the pressure that we all have within us as the guy above me stated. Take for example, a balloon with 2 atmospheres (just a way to measure pressure innacuratley)
would be normal in a 2 atmosphere environment but when placed in a 1 atmosphere environment (Earth), it would pop as it expands. If placed into a 4 atmosphere environment, however, it would shrink and collapse and be "crushed" as you have put it.
And as so, we are not crushed by earth's atmospheric pressure but if we go 15,000 feet deep into the ocean where the pressure can reach 1,000lb per square feet, we would be crushed in a second.

There is a limit that every human body can withstand some highest and lowest pressure and since the atmospheric pressure is within this limit human can with stand this pressure.
How do our lungs work? If it cannot exert a pressure more than the atmospheric pressure how can we breathe out air

because we have the same atmospheric pressure inside us. There are many experiments you can do to use atmospheric pressure to crush metal cans.

Because we have the same blood pressure inside us so the 2 forces cancel each other out.

our body experiences about 2 atm pressure per metre .but this is counteracted by our body's blood pressure.thus we dont feel the pressure exerted by the atmosphere.

the atmosphere pushes you in and you push back. your body was made for this amount of pressure. if you go way down in the ocean or out in the vacuum of space, you would not be so lucky. in fact, you'd die.

Because we have the same pressure inside us (lungs, etc) so the 2 forces cancel each other out.

Because we are invincible! Or the atm pressure is just a whimp!
