You overly discount the intimidation of gyms, but I agree you can definitely find one that works for you. They range from young & beautiful to very specialized and accepting. I suggest you try a community run or neighborhood (doesn't have to be your neighborhood!) as these tend to be very low key, and probably significantly cheaper.
Motivation for gym work can be a huge problem; what suggestions do people have for that?
I was hoping to convey that the intimidation factor is completely made up and it just stems from your own self-doubt based on your (not you specifically) own conjured up straw man.
I agree with your general suggestion though too. Though from the sound of the scenario the OP was describing there probably aren't many neighborhood gyms. But hey maybe the OP or someone in that scenario could start a friendly gym?
