Britney Spears gave a gift to her 23.3 million Instagram followers on Sunday, when she showed her favorite workout routine.

The 38-year-old pop star posted a video of herself practicing yoga on the grass.

The quick-motion clip showed her youthful figure in a vibrant green bikini, while she was sweating.

‘Another day in yoga … consistency is the key. With me it is like a prayer. Such a beautiful day … speed of God and God bless you, ‘he captioned the photo, followed by a group of emojis.

Britney arched her back and also showed her flexible legs in a lateral angle position.

The singer let her long blond locks hang on her back in wavy tendrils, and completed her minimalist look with a pair of bright white sneakers.

He didn’t specify where he was, although he seemed to be doing some exercise in the backyard of his mansion in Thousand Oaks, California.
