900 lbs of cement and sand and various masonry materials. Loaded, and now in the process of unloading. I had to take a break.
It's less than half a ton. I've done a ton or more with no problems. It might be the 90-plus lb. bags all at once-- the 50- and 60-lb. bags are still pretty easy.
I'm weaker than I used to be. I've probably lost muscle tone from a lack of protein. Lifting and carrying over 100 lbs. of dead weight used to be nothing... well, not nothing, but I could keep it up for an hour.
I have a weight bench that's still in the box, a bar and free weights. I need to put it all together and start using it.
But not tonight.
