Planets gravity and survivability

Based on the Newton's law of gravity

$$g= \frac{GM}{r^2}$$

we calculate the gravity acceleration, gravity exerted, etc.

And now, provided there exist the correct gasses to create a humanly survivable atmosphere, the only thing remaining is to have just enough gravity so that the gasses don't escape. And boom: we have our atmosphere.

Now on to my question:

I want to have enough gravity so as to handicap the humans a bit, but not cause them problems, whether that means more or less gravity.

I'm leaning towards less gravity, but, what's the limit I can reach, without destroying my atmosphere, and being able to have them live in it for an extended period of time without many long term health problems?

The loosening of the skeleton and weakening of our muscles is somewhat acceptable within a limit.
