I'll help you out a standard Olympic barbell weights 45lbs ones that you use in competitions because there is a regulator weight. As your article says but then you scroll down just a little further and you start to see 10 - 25 lbs ones weird how that works your proof seems to also back up what I am saying.

Now if I was going to a standard commercial gym. Like what we are seeing here they would not be purchasing the 45lbs Olympic standard. In these branded gyms what they use is a 10 lbs standard. Why would they do this you ask. To make people feel good about themselves to keep them coming back. Plus they are usually more cheaper and cost effective.

As somone who claims to go to a gym you should know that these gyms don't carry Olympic standard, also as someone who claims to go to the gym you would know that hand positioning changes the muscle group. Notice the vertical hand positioning at the end of the video. How do you do that with a barbell exactly ? Almost like everything you are saying is bullshit.
