Try to carry something that is close to the amount of weight that you lost... Yesterday I attempted to carry two tubs of cat litter up the stairs from the basement. They are each 40 pounds full, but one was only about half full. I'm gonna say it was like 65 pounds total. I couldn't do it.
I have lost up to 78 pounds. It's INSANE to me that I was just walking around carrying two tubs of cat litter. I literally dont know how I used to carry just my body up the steps! INSANE.
