You have elderly people at your gym who have size on them?
The problem I have with Gold's, and most other large commercial gyms, is that they only keep the quipment in stock that generates the most money. Cardio machines bring in the soccer mom's who plunk down their membership dues a year at a time, then never come back. Weight equipment brings in the "wrong" type of crowd, i.e. the Prof. X's, that scares off the soccer mom's. They have some equipment sure, but they only keep their cardio stuff truely up to date.
Case in point - the Gold's around here has 20+ ellipticals, 40+ treadmills, numerous exercise bikes, and 3 or 4 rowing machines.
They have 1 squat rack...
