Britney Spears opened up about her struggles with self-esteem in a revealing Instagram video. The 37-year-old shared what she does to combat those negative insecurities.

In her most recent Instagram post, the "Toxic" singer shared video clips of her talking to the camera and doing acro-yoga with her coach.

"Body language is everything!" she wrote to caption the video clips. "The way you speak to yourself and carry yourself can [affect] your mood .... I have self-esteem problems so I slouch ... These poses help me every day become stronger and it’s quite fun doing them."

"I feel so different every time I do it," she added. "Cause I’m not used to the feeling of my back being out !!!!"

In the first video, she describes how working out has helped her feel physically better. "Basically what I'm going to do today with my gym coach is basically arch my back," she told the camera.

"By hanging upside down it opens my back and it enables me to breathe better and to open up and to feel better," she said. "So here I go," she added while beginning to demonstrate the moves.

Spears climbed atop of her coach's legs and began to do the acro-yoga poses and stretches where she balanced on top of his feet while "Fields of Gold" by Sting played in the background. Hey

The pop singer has seemed to have gotten her groove back, after a rough year of dealing with the legal battles of her conservatorship.
