This probably sounds like a pretty dumb question but want to see if anyone has experienced something similar and knows why!
I've always trained in standard commercial gyms with rubber coated plates and standard cheapish barbells then last summer I started to set up a gym in my garage, got a Texas power bar and a bunch of standard 100% metal plates.
Long story short I still work out at both my local gym and in my garage and every time find the weight in the garage feels significantly heavier and I get far fewer reps per set.
I've weighed the plates I have and they are what they say they are (give or take 0.5lb ish). I've also done a few meets using calibrated plates and hit prs having only trained at the commercial gym beforehand so don't think the plates there are lighter than they should be.
Would love to hear if someone has had a similar experience as its driving me mad!!
