Explain how finances be a barrier to keeping physically fit?

An individual's finances can affect the means by which they can do physical activiry, which in turn affects their ability to keep physically fit.

If, for example, an individual has a small amount of finances to their name, they may not be able to access specialized equipment that would normally be found in places such as gyms (which require a paid membership most of the time).

In short: There's only so much one can do for free and without any kind of fitness equipment.
