Besides, I'm a lone wolf. A solitary eagle.
haha, I like that.
I'm the same. Even if I have training partners, I don't take a spot or help to get into the starting position. I've just always done it this way, from when I started training in my bedroom, then garage, then when I started training on my own in the gym. It's actually never felt like a problem. I done it when all I could bench was 12-14kg DB's and I do the same with 50kg DB's.
My biggest fear is what Hoose pointed out - basically destroying someone with a flying/bouncing 50KG DB. I'm certain there's some kind of scanner at the door of every gym that injects people with a dose of stupidity and takes their common sense as a deposit. It's unbelievable the stupid things I constantly see from fully grown, adult, independent men who have full time jobs, their own car, house, even kids, some even have their own business, and appear to do very well. Yet they come into the gym and describing them as "stupid" is practically a compliment.
Slight rant but, it's true. You would think seeing someone DB benching with a 50kg DB in either hand would you know, make you not want to practically tea-bag them so you can get prime mirror position for your EZ curls. You might want to stand back a little and maybe forfeit the mirror for just one set of your training life just encase one of those 50KG's goes wayward and smashes your lower leg.
My gym was re-arranged very stupidly and now the DB rack is in front of a mirror which is close to the bench press. So now you get people swarming around the rack infront of the mirror, crowding the bench press which is side on, and they have their back to it. All so they can do curls infront of the mirror. There is always plenty of space away from here. I've seen people walk into the end of the bar mid set. I now need to spot the bench press with one eye on the lifter and one eye on DB rack, to make sure no bumps into the bar mid set.
Before I worked in the gym I figured a smashed -insert body part- would pretty much serve the person right, basically being a painful lesson for them to learn. Like when I was 10 years old and tried to jump 15-ish foot out of a tree. Not my smartest move but the broken leg ensured that i've never attempted anything like that again. However now that I work there and have insurance etc, I have a slightly different opinion i.e the law seems to be on "Stupids" side.
p.s Try going for a 1 rep max on Turkish Get Ups. This can only be attempted if the gym is quiet. The DB literally can go anywhere. A clients recently failed attempt ended up with the DB bouncing out of the free weights area lol. There seems to be a skill involved in getting out of the way but I've not figured out how to teach it yet.
