Britney Spears says she knows she's not perfect but that she's trying to give boyfriend Sam Asghari's abs a run for their money!

We feel confident Ms. Spears will get there -- 'cause she's working out like EVERY DAY and documenting it all on Instagram, thank god! Brit's near-daily exercise clips are like having your own personal trainer. She DJs with inspirational music, shows us the repetitions, and all while wearing a sports bra and short shorts!
