He's body image

I asked my husband why we're not having sex lately, it's been over a month. He bluntly told me, he feels disgusted with his body and is working out to get back in shape. He's lost weight and the body muscle he used to have. I think he's been looking at our videos we've taken in the past few days and is hitting him hard. I told him I completely understand but to me he's beautiful and sexy regardless what he thinks of himself. I'm sure he can tell when we have sex, I'm all over him. And I want that again. I don't want to push him too much but I miss him, any tips to spice it up? I'm scared he'll reject me, it might take a few months until he gets his desired body image and don't think I can wait that long for sex.
