Ronda Rousey's striking was her undoing at UFC 193, when she lost her UFC Bantamweight Championship to Holly Holm.
The former champion Rousey looks to be doing her due diligence to make sure that doesn't end up being the case against Amanda Nunes during her return at UFC 207. Rousey brought in Olympic boxer Mikaela Mayer to work with her ahead of the December bout.
Mayer represented the USA at this year's Summer Olympics in Brazil in the 60 kg weight division. She nearly medaled, but was eliminated in the quarterfinals by Russia's Anastasia Beliakova.
In the past, Rousey has worked with the likes of Vic Darchinyan, which you can check out above. You can also see a photo of Rousey with Mayer below.
