Gymnastics is the Eye of Rebirth. Five Tibetan Pearls

I recommend doing these simple exercises every day. They will take you no more than five minutes.

This practice has been known for a long time, so you can use any resource to get acquainted with it in more detail. There are enough links on the Internet. But you can not bother too much and just do it.
