I think I've been robbed by my barbell supplier.
I've got a home gym with cage, barbell plates etc that I use all the time but I also work away sometimes. This last two weeks I've been using a commercial gym and all of my lifts seem harder at the same weight. I'm convinced my home barbell is only 15kg when it was meant to be 20kg. Its a 7ft bar. All my PRs are now in tatters. I need to weight the bar when I get home.
If it isn't the bar, what else could it be? Why am I struggling more in commercial gyms than my home gym? Could it be mental? I don't feel anxious about lifting infront of people or anything.
Home gym master race.
