1. Get a compression check kit, like this

2. Remove all spark plugs

3. Screw the fitting into a spark plug hole

4. Have a helper crank the engine 3-4 times

5. Write down highest reading

6. Repeat for each cylinder

7. Profit

Your readings should be consistant with each other, a "bad" reading would be one cylinder 30-40 psi lower than the rest.

Look for an average of between 120-160 psi. It varies with the engine.
