Well, you could use <small>(all 3 gyms)</small>
and adjust the size with CSS if you want the text to be even smaller. For example <small style="font-size:7pt;">(all 3 gyms)</small>
And you might want to remove all but one of those <tr>
tags, and add a closing </tr>
after the </h4>
(which isn't properly nested, but as long as the table looks the way you'd like it to, it probably won't be much of a problem)
Hope this helps,
