I get the annoyance, that said, you should cut this guy some slack. At least it shows he cared about your well being. Much better than all the trainers who watch members do terrible movements and say nothing.Yesterday i was doing pendlay rows with 315 and the gym employee (hes not a trainer screw that) told me i was going to injure myself and that i should use the rowing machine they have... so annoying. Its an absolute necessity that i find myself a new gym now. Cheap or not, i cant take this anymore.
You should get this guy a cup of coffee to say thank you instead...lol
