In the video ahead, the teenager named Charles can be seen following the warning and using the mats while deadlifting. The noise is still pretty loud but this is the maximum Charles could have done, even after the warning. 40 seconds of the video goes by when we can see a man walking in Charles direction, on purpose. The youtube account of Pete Rubish that posted this video attached in the next slide gives this account: “The backstory is that the staff at a Buzz Fit gym in Montreal, Quebec have given my client a hard time in past weeks about deadlifting too loudly in the gym. They said he still could, but he had to place mats underneath the plates.”
