The gym can be a great place to go. Do some cardio, lift some weights or do some weight machines. However, the gym seems to be a hot spot for a lot of people to go that really have no interest in working out. These varied groups people come to the gym for many reasons, to be seen, to fish for compliments, to find partners, to fit in, etc. The point being that none of these people are really there purely to workout, or for health reasons.
The most annoying group are the short men with inferiority complexes. They are short, and they are overcompensating for their lack of height with obsessive devotion to muscle tone and an aggressive persona. These guys are usually just standing around looking for an excuse to start a confrontation. Of course none of this will make them any taller, or hide the fact that they mostly shop out of the children's section. However, to be fair, they are actually doing some exercises between (and sometimes as part of) all their overcompensating. So they have a legitimate reason to be at the gym.
Next we have a group of women. Older women with to much plastic surgery. They are at the gym to collect compliments on how good they look. Ironically nothing about their looks has anything to do with going to the gym or a regular workout. They have facelifts, fake tits, liposuction, and clothing that was meant for a women at least half their age. Do they look good for their age? Yeah, but they should after 100k spent with a plastic surgeon. What they really want is for people to think they are much younger than they really are, but that never really happens. No matter how tight the skin on your face is, or how perky your tits might be, your skin and hands will always give your age away every time. 50 year old skin will always look 50 no matter how tight it is, or how much silicone you get underneath it.
Then there are the steroid enthusiasts. These are mostly men. They have bulging muscles, bacne, and shrunken testicles. They are at the gym every chance they can get. They might go to the gym more than once a day, that is if they ever leave it at all. Much like the first group, they are legitimately getting a workout, they are just taking it to an unhealthy extreme.
There are other groups at gyms. Maybe we will talk about them some other time.
