I wouldn’t mind. I may not take your advice - but I wouldn’t mind hearing it.
I take a boot camp class (with a really good trainer) but he can’t be everywhere at once - and often the others in the class have offered suggestions on form that really are helpful.
Fit, at the gym usually 5 days a week. Girl.
I was talking to the manager of my gym this morning and I told her about this question and asked her opinion.
She said that if she was working out in her own clothes and wanted to offer advice to someone she would take into consideration how well she knows them. If she had never seen them before she would tell one of the staff on duty that perhaps they need some help. However if she knows them well she would go up and say hello and subtly advise them.
I did a few winters powerlifting and absolutely depended on advice from other lifters on technique and form. Have to say that none of it was unsolicited, I’d usually ask. The properly strong guys were always very polite and reasoned in their advice, not sure if it’s a general trend. I noticed similar when I did martial arts, the real bad men where the politest guys in the room.
There were few, if any, women in the room I lifted in, so it would be odd if one of the female gym instructors went in and started dispensing advice. I’d still listen, mind - I found the weight room a very contemplative and respectful place in that regard.
With the heavier weights you probably need to give out advice more often if you’re a trainer type - I’d never in a million years consider commenting on the fine details of someone’s form, but I’ve had to say something once or twice when I’ve seen a blatantly unsafe deadlift or squat.
