Comment on Weight Lifting: How are you supposed to know the weights of unlabled things?
litchralee@sh.itjust.works 6 months agoI agree with wanting to know the empty weight for machines. For my leg press at home, I forgot to weigh the sled/carriage before fully assembling the machine. So I did the next best, which was to measure the uphill force of the carriage at its 45 degrees, using a cable that pulls uphill and dangles vertically off the top of the machine. I then progressively loaded the cable with plates until it started to move the carriage.
The force uphill is sqrt(2) of the carriage weight, so I multiply the plates by 1.41 to arrive at the empty weight. This is only useful when I compare to the leg press at the office gym, though.

That is some ingenuity! Smart move.
I am lucky that I have been working with a trainer for a couple years, and she knows this info for every piece of equipment in my gym. It will get harder as I taper off working with her.
