I'm 16, female, and 5''6. I see boys about my age all the time using the squat rack on their own, though its mostly middle aged men using the 2 that are at my gym.
Today, some random old dude (looked like he was in his 60s) got off his treadmill and came up to me to say he's not sure I should be squatting weights unsupervised. I usually use the Smith machine and lift double the amount, and when he came up to me I was only doing 10kg so I was a bit confused what the fuss was about. I had proper form, wasn't doing many reps as I was just working on form, and wasn't struggling whatsoever. I don't look particularly young either, so I'm confused as to why I was told this?
Any comments would be appreciated - imo his tone was a touch patronising and it might've been sexism because well you never see girls on the squat rack but hey
