The pop star, 35, shared a montage of an outdoor arm workout combined with some exercises on a yoga mat in the gym to Instagram on Sunday. The video was set to JAY-Z‘s song “BBC,” which features a reference to Spears’ famous “Britney, bitch” lyric.
“When this song came out, I lost my mind like a little kid!!!” the singer captioned the post. “I fangirled and cried!!”
Spears donned a pink sport bra and purple shorts that showed off her toned abs before sporting a grey top for her indoor workout.
Spears is a documented fitness fanatic who gives fans a peek into her intense gym sessions – and showes off the results on Instagram. It’s not rare to see her breaking for selfies mid-split to doing an impressive handstand in only a bikini top when browsing her social media feed.

Spears previously said having her sons — Sean, 11, and Jayden, 10 — changed her approach to exercise.
“Daily exercise is important for me both mentally and physically,” Spears added. “I don’t mind working out. Trainers keep you motivated, but I don’t have a problem being motivated.”
