exercise widow

(名詞) 運動寡婦:因丈夫經常花長時間在運動上而與丈夫「聚少離多」的女子。

當然啦,若是男子則稱為 exercise widower (運動鰥夫)。

The exercise widow often wakes to an empty bed—a sure sign of a morning workout—and may find dinner plans spoiled by a sudden avoidance of anything heavy before a night run.

Dear Amy: My husband ... has become so obsessed with his exercise program that he has little time or energy for me. He goes to bed shortly after our children do and wakes up early to work out. ... I have talked to him about this. He makes an attempt to be with me, but then goes back to his routine.—Exercise Widow
