WWE's Natalya has been training with UFC Women's Bantamweight Champion Ronda Rousey. Natalya noted on Twitter that she is getting in the best shape of her life for NXT Takeover, posting a photograph of her day with Rousey and 'The Four Horsewomen' MMA team. As you might have guessed, the Four Horsewomen is a tribute to Ric Flair's legendary 'Four Horsemen' stable. Rousey is a huge WWE fan, leading to some speculation that she might get involved with a WrestleMania after her UFC career has peaked. That would certainly be something WWE would be interested in, Rousey is a pay-per-view sensation, the UFC's top star alongside Men's Light Heavyweight Champion Jon Jones. Rousey has noted she watches Raw every week, previously commenting that she finds CM Punk "sexy". Natalya choosing to train MMA with Rousey is indicative of the growing appreciation in WWE of the UFC lifestyle and fitness regime. Even Stephanie McMahon has been training in jiu-jitsu, visiting the ex-WWE diva Eve Torres at her Gracie Women Empowered Self Defence Academy. Training in MMA is clearly the 'in-thing' right now in the physical workout world. Natalya also spent her day with MMA fighter Josh Barnett. While her appearance with Rousey is notable, a WWE star and UFC star, it's vastly unlikely that Natalya could ever pursue MMA further. The women's game is still an emerging force, but the barriers to entry would be beyond Natalya, she would need to possess at least some top level discipline in either wrestling or jiu jitsu. Natalya has no real combat experience, so expect her to stick around in the WWE ring.
