Ronda Rousey is preparing for what could be the toughest battle that she's faced in the UFC to date in the form of Bethe Correia. 

The undefeated Brazilian will face Rousey at UFC 190, and it looks like Ronda is in pretty good form, judging by these short sparring videos that she shared on her Instagram account. 

They show Rousey dominating her training partner, landing some powerful punches and submitting him with ease.

She also uploaded some footage of her practising some pretty hard shots, so there's no questioning that, while she admits she's not going 100% yet, she's working damn hard to keep her title.
