R<span>ousey explains to </span>USA Today:<span>
</span>
<p style="padding-left: 30px;"><span style="line-height: 1.5em;">The ESPN Body Issue is about celebrating the peak of human potential and the kind of form the human body, when specialized, can really look lik. The Swimsuit Issue has a lot more [of a] sexual side to it, while I don't think the Body Issue is overtly sexual whereas </span>Sports Illustrated<span style="line-height: 1.5em;"> is. </span>
<p style="padding-left: 30px;"><span style="line-height: 1.5em;">The difference in how I approached it is when I posed for ESPN Body, I really tried to be a lot more cut and a lot more close to my prime fighting shape because I was being photographed as a fighter and trying to look more like a fighter.</span>
<p style="padding-left: 30px;">I purposely tried to get a little bit heavier for the SI issue so I was a little bit curvier and not in top fight shape look but the look at which I feel I'm the most attractive. It's very natural for a person's body to go through seasons.
<img src="http://static2.businessinsider.com/image/54e4d7786da811860cbfaec3-820-1200/x158908_tk1_01448-rawmasterwmsm.jpg" border="0" alt="Ronda Rousey Sports Illustrated" style="line-height: 1.5em; color: #000000;">Rousey is no stranger to gaining and losing weight quickly.
In order to maintain<span style="line-height: 1.5em;"> 135 pounds, the weight limit for the women's bantamweight division, Rousey must make sure she's not a pound over when it's time to fight.</span>
To ensure she'll make weight, Rousey explained to the New Yorker that she goes on an incredibly salty diet for a week so that her body bloats. Then when the fight is close, she removes all salt from her diet so her body lets go of all of that fluid with the help of a steam room.
Before a fight in February 2014, a typical breakfast for Rousey was eggs, turkey bacon, and spinach with a lot of pink Himalayan salt.

"There's nothing put in place for Olympians after they're done. They give you a couple grand, a handshake and they kick your ass out the door," she </span>told MTV<span style="line-height: 1.5em;">.</span>
Rousey was forced to take a graveyard shift at a 24 Hour Fitness in California while trying to figure out what she wanted to do.
In 2010, she returned to fighting at an MMA gym in Los Angeles. <span style="line-height: 1.5em;">In just seven months, she went from an out-of-work ex-Olympian to a professional MMA fighter, winning her first fight in 25 seconds.</span>
<span style="line-height: 1.5em;"><img src="http://static2.businessinsider.com/image/52bdd6ea6da8112749ce32ee-800-600/ronda-rousey-arms-raised.jpg" border="0" alt="ronda rousey arms raised"><span style="line-height: 1.5em;">When the league she worked for, Strikeforce, announced it would shut down in 2013, t</span><span style="line-height: 1.5em;">he UFC scooped her up immediately, making her its first female fighter ever. CEO Dana White, who previously vowed to never employ a female fighter, said, "I think she's going to be a big superstar."</span></span>
<span style="line-height: 1.5em;"><span style="line-height: 1.5em;"><img src="http://static5.businessinsider.com/image/54e50b32eab8eaa008f8ab63-1200-600/ronda-rousey-dana-white-3.jpg" border="0" alt="ronda rousey dana white"><span style="line-height: 1.5em;">Since then, Rousey has </span><span style="line-height: 1.5em;">made the sport mainstream in a way it had never been before and opened the door for more female fighters to join UFC.</span></span></span>
<span style="line-height: 1.5em;"><img src="http://static5.businessinsider.com/image/54e50c00ecad04f427cfe5e1-1200-858/ronda-rousey-ufc-2.jpg" border="0" alt="Ronda Rousey UFC">She has over a million Instagram followers.</span>
<span style="line-height: 1.5em;"><img src="http://static4.businessinsider.com/image/54e515b269bedd51507dac46-1035-726/screen-shot-2015-02-18-at-5.42.32-pm.png" border="0" alt="Ronda Rousey Instagram"><span style="line-height: 1.5em;">And has dabbled in modeling, appearing in a current campaign for Buffalo jeans.</span></span>
<span style="line-height: 1.5em;"><img src="http://static1.businessinsider.com/image/54e504a3ecad048601cfe5e1-1200-572/ronda-rousey-buffalo-sponsored-athlete.jpg" border="0" alt="ronda rousey buffalo "><span style="line-height: 1.5em;">But now, she also has her sights set on acting.</span></span>
<span style="line-height: 1.5em;">In 2014, Rousey made her <span>major motion picture debut in "Expendables 3."</span></span>
<span style="line-height: 1.5em;"><span><img src="http://static4.businessinsider.com/image/54e504686da811766f2d7d2e-1200-800/ronda-rousey-expendables-3.jpg" border="0" alt="Ronda Rousey Expendables 3"></span><span style="line-height: 1.5em;">This year, she will appear in "Furious 7" and play herself in the upcoming "Entourage" movie.</span></span>
<span style="line-height: 1.5em;">"I'll keep fighting and filming together. Having them both allows me to do each one longer," she tells USA Today. "I'm able to step away from one and allow myself to miss the other. I've found an amazing balance. I'm always happy and engaged and motivated."</span>
<span style="line-height: 1.5em;"><img src="http://static2.businessinsider.com/image/54e5112169beddae387dac44-1200-858/ronda-rousey-expendables.jpg" border="0" alt="Ronda Rousey expendables"><span style="line-height: 1.5em;">Rousey adds that creating new goals for herself keeps her motivated.</span></span>
<p style="padding-left: 30px;">I love fighting and it's my passion and it's the reason Hollywood took an interest in me at all, but I'm no dummy. I know there's a short shelf life in the sport and I don't want to be left out like I was after the Olympics [she won a bronze medal in judo at the 2008 Games in Beijing] with no options. I need to have a new grand goal to go after because when I have no goal is when I get depressed and I'm not letting that happen again.
<p style="padding-left: 30px;"><span style="line-height: 1.5em;">I set extremely high goals for myself. The first day I stepped onto a judo mat I was like ‘I'm winning the Olympics,'" she said. "The first day I did MMA, ‘I'm winning the UFC.' The first time I had an acting gig, I said ‘I want to be the highest-grossing actor in the world.' That's what my goal is.</span>
