1Rib Cage Bragging
The term was coined by Mail Online (shame on you!), who point towards celebrities including Bella Hadid, Rita Ora, Nicole Scherzinger, and Kourtney Kardashian for popularizing it with the uploading of bikini pictures showing their ribcages loud and proud.

Fox News Medical A-Team physician, Dr. Marc Siegel said the ab crack is a deceptive goal for people to attain: “There is nothing healthy about it, except insomuch as thin is healthier than heavy.

To do the move, you apparently first exhale, pushing your stomach out. While holding your breath, you then pull your abs up toward the chest. Then you isolate your abs and roll them from side to side. This move is called "nauli, " and it's meant to cleanse the digestive system and strengthen the core through a series of abdominal movements. It can also supposedly correct hormonal imbalances, improve willpower, and produce happiness and emotional stability.
Nauli is not recommended for people who are pregnant, suffer from hernias, ulcers or heart problems, and should always be attempted in the presence of a professional yoga instructor. (Source)
5A4 Paper Challenge
The A4 Waist Challenge encouraged women to stand behind a piece of white paper to see if their waistlines were thinner than the 8-inch wide piece of paper. This challenge also had its start in China before spreading globally.

However, what might seem like a harmless pose contributes to a warped version of the ideal body type and a pretty hefty eating disorder. (Source)
Of course, like most of the challenges on this list, the trend was seen by experts as promoting an eating disorder, and some social media users weren't having it either. They poked fun at the collarbone craze by balancing random objects—from half-eaten candy bars to bottles of vodka—on their chests. (Source)
Vonda Wright, a Pittsburgh-based orthopedic surgeon and fitness expert, said the spacing between a person's legs is based mostly on genetics. Even thin people may not have a body type that can achieve a gap, and most won't have a thigh gap because their thighs are muscular enough that they touch. (Source)
The bridge started as a hoax in 2014 when Buzzfeed posted an article entitled "12 Perks of Having A Bikini Bridge." But within just 24 hours, the bridge snowballed with #bikinibridge and #bikinibridge2014 tweeted thousands of times. This type of trending "thinspiration" was immediately panned by experts,who said it put pressure on women to feel increasingly anxious about their bodies. (Source)
