There is a video going around called the "baby-swinging yoga" video, and it looks too crazy to be real.  But it is.  It shows a Russian woman swinging a baby around by its arms and legs, and she swears it helps babies the same way yoga helps adults.

And she even owns a legit baby-swinging business in Egypt.  But experts say it's VERY dangerous, and it's not beneficial for babies at all.
