Like ds asked... what exactly does this mean?
And I'm assuming they do have other gym basics like assorted benches (flat/incline/adjustable), pulldown/cable stations, various bodypart machines, leg press, etc.
That mostly depends on what you plan on doing there. Think of your current abilities (strength-wise), think of your short-term goals, and think of the types of training/workouts you'll need to do to get from point A to point B.
Do you think you can design an effective training program using the equipment available here? Maybe you can, maybe you can't. Maybe it'll be too much of a hassle and you won't progress very quickly.
If it's a ridiculously good discount, it might be worth it. But ideally, I'd find someplace that has a more complete selection of free weights.
