The carriage of the leg press machine at LA Fitness weighs 100lb on its own. I have not been calculating that into my lifting. I have been lifting an extra 100 pounds for the last 6 months and didn't even freaking know it!!!
So today I wanted to see how much my max lb x 1 rep was: 510lbs. YAY! After that when I was doing my normal leg presses I happened to over hear this employee explaining to a woman about the machine, which is how I learned about the carriage.
I feel dumb, but at the same time excited because its cool that I was lifting that much extra.

I just googled this picture; this is not me.
