Is it common for men to tell their female s/o to do heavy lifting to save installation charges?

My s/o is insistent that I help him lift a new, sixty pound microwave up in the air over the stove since the other one broke. Before this, it was a lawn mower into the back of the car. He already has a hernia but has no idea what that means (in the abdomen). Is this a common request from a man to a woman? They wanted $100 to install it but he wanted to “save the money.” I don’t see something this risky as saving anything.
