The mass of the air is 10000 kg, but the weight is 0. Make sure to avoid this common mistake when looking at objects here on earth. Weight is a funtion of mass, gravity, and in some ways density.
The only real way to be "crushed" by air is by increasing the pressure. If you put 10000 kg of air in something the size of a basketball (several million PSI), you would liquify Titanium!

There are approximately 14.7 lbs of force per square inch on our bodies caused by air.
Luckily, we have the same amount of pressure inside of us.
Think of it like this.
If you blow up a balloon underwater and then let it float up, it will pop when the pressure outside dwindles enough.
The reverse is also true.
Assume you have a hollow glass ball. If you bring it deep enough in water it will inevitably implode. However, if you poke a hole in it (Assuming the hole doesn't break it.) it won't shatter.
It works the same way for our bodies. When you put your arm out in front of you, it will have 14.7 lbs of force pushing down on it per square inch. It will also have 14.7 lbs pushing in all other directions as well.

The fluid inside our bodies exerts and equal outward pressure that the air exerts inward. Also, the air exerts pressure on all surfaces of our bodies, so that it pushes up as well as down.
