I was doing the lateral pulldown exercise today when out of nowhere a personal trainer appeared and began to tell me how wrong I am doing the exercise and how I will get myself hurt. I had to tell him "I'm all good" 5x times in order for him to leave me alone, and this was a clear case of him trying to sell me his services. I have been doing this exercise for bunch of years without any accidents and now he tells me that I will hurt myself.
