Well thats ridiculous. If I want to be in contact with someone or my dog is sick or my friend needs someone to talk to I'm not going to ignore them because I'm working out. I dont lift less weight because Im txting between sets. And also sometimes Im just changing music or writing down my new PR or something.
But the point is you're taking up equipment because you want to sit there on your phone and console your friend or talk to your sick dog. I understand people change their songs etc. on their phone but anything outside of that can wait. Or at least get off the equipment and take care of it somewhere else.
