Move hubby so that he is sitting facing away from you, or if he's laying, so that his head is toward you and feet away.
Reach under his armpits and raise his upper body to sitting, then slid your arms under his armpits from behind.
You must be in a squatting position, if he is too heavy for you, you won't be able to lift him. Rise from your squat, you are then lifting him with your legs, your arms are just jammed into his armpits they are not doing the work, nor is your back.
If he is still too heavy for you using this method, then he's just plain too heavy for you and you need help.
I've carried passed out drunks this way who outweighed me by over a hundred pounds, but hubby may still be too much for you.
This is terrible advice. If a person has fallen, call for help. It's too much of a risk to do more damage if you move them.
