虐腹 [nüè fù] v. Abuse+abdomen. To do intense ab workouts, especially to develop a visible Adonis belt or a V-shaped core.
Fit people just have springy feet. —Consort Hua “The Legend of Zhenhuan”
[Note: The original line is “Bitches are always pathetic.” 贱人 “despicable person” and 健人 “fit person” are homophones—[jiàn rén], while 矫情 [jiáo qíng] “pathetic” sounds like 脚勤 [jiǎo qín] “physically active, especially in walking or running.”]
