I often hear weight-lifters lament the conversion/removal of hardcore iron dungeons in favor of more mainstream workout facilities.
Honestly, what would be so great about
regularly training in a Metroflex or Temple?
From my perspective, the negative aspects are substantial:
1) Access to equipment.
- It is well known that serious lifters generally perform more sets of any given exercise. In addition, they are more likely to use the limited equipment highly sought after by serious lifters (squat racks, the narrow benches, etc). Their attitude and focus limits the possibility that they would be willing to let another user work in with them, not to mention that few train alone, so you must take into account the length of time their partner(s) take as well.
2) Attitude / Annoying Habits
- In general, the serious trainers feel entitled to more "space." They generally occupy more territory than the average gym participant, and remain planted for much longer. I've trained at hardcore gyms such as Hercules, and feel like I'm walking on eggshells around many of these guys. Although mainstream gyms have problems (such as curling in the squat rack, groups of 4-5 guys alternating on a bench), these problems are exceeded by the hardcore facilities (working out in front of the mirror while limiting access to dumbbells, planting their gymbag on the seat of good equipment while they're not using it, supersets, giant sets, etc.). The problems presented by the hardcore facility are much more difficult to circumvent too.
3) Microcosm
- These hardcore facilities have a smaller base of guests, so it is difficult for newcomers to get established. On the same note, it is far more risky to be assertive due to the possibility of pissing someone "important" off. People in smaller hardcore facilities have their workout routines firmly entrenched, and are not as willing to deviate to secondary alternatives if you're somehow "in their way".
Imagine occupying Ronnie's deadlift platform / squatrack when he first arrives to Metroflex??

The subtle rules, the implicit seniority, are distractions and a dedicated trainer should not have to memorize other people's routines, just simply have the freedom to do their thing yet be willing to find a suitable alternative should a conflict arise.
Don't get me wrong, I do understand the benefits (ambiance, motivation, camraderie). Unfortunately, its largely cosmetic and of peripheral importance to a bodybuilder's primary quest: to build muscle. It is far more important to perform the right exercises with the right period of rest in between sets to promote hypertrophy, and from my experience this can be accomplished more efficiently within a standard gym.
I've trained in a variety of gyms (university, boarding school in a weightlifting class, YMCA type public gyms, on-base military gyms, home gyms, exclusive "spas", private gyms, and hardcore facilities). In my opinion, the standard gym that many bodybuilders bitch about is in fact the most conducive environment for a good workout.
