IFBB Bikini Model

Surrounded by health and fitness by her father, it was in Marissa’s blood to compete. Making a resolution in 2013 to change her body, she stepped into the gym with a goal in mind to win her Pro card with the IFBB.

Marissa’s not only achieved her goals with the IFBB and become a Pro, she’s also known for her background in dance and competitive cheerleading, and this is her story:

“I am extremely competitive if I want something I’m going to go after it! No excuses! You have to be willing to do what others won’t to achieve what others don’t!”


Cheerleading To IFBB

Marissa first became inspired by her father who was always interested in exercise and healthy eating. Although she didn’t walk into the gym until 2015, Marissa always appreciated people who would keep fit and strong.

Before her competitive history started in bikini modeling, Marissa’s also know for being a professional cheerleader and dancer, she would compete in national championships across America.

One day she decided to change her body and document it on social media.“It was kind of a New Year’s resolution type thing” recalls Marissa. Her friend who’d competed before was the one who gently pushed Marissa into training, seeing that her friend was full of potential.

Becoming Hooked With NPC

Not being altogether familiar with the NPC competitions that her friend took part in, Marissa went to a show and was blown away, this, she recalls is what got her hooked. “The first show I went to I was hooked and decided to make it my goal to one day step on stage.”

Marissa’s friend and bikini competitor eventually persuaded her to compete. In 2015 she stepped into the gym with a serious goal in mind. She gave herself 6 months to get stage ready.

Not only did Marissa manage to get her body in peak condition, she also smashed the competition and took 1st place in her very first show, which also qualified her for the nationals.

Team Edge Partnership

Marissa took her goals very seriously and trained rigorously with her coach Ingrid Romero, in the process, she met Joe DiScuillo (a professional bodybuilder) through social media. They hit it off immediately and soon became partners, and later husband and wife. They both saw how incredibly well they worked together, not only as a couple but also as business partners.

They decided to create a partnership with their brand “Team Edge”. The company supported Marissa in getting ready for her first NPC show, which took place on June the 8th 2015.

“I made the gym my number one priority and joined Team Edge. I gave myself six months to prep, and by June 8th I was on stage at my first show where I placed first.”

Winning Her Pro Card

Marissa built herself up quickly and won her pro card with the IFBB after only two shows in the NPC division. Her first competition took place in June 2015 taking the 1st in the NPC, this is where she qualified for the nationals.

After tasting victory in the NPC, she knew that the IFBB was within her sights, Marissa decided to get her feet wet one more time in the NPC to see what she could do. Marissa took 1st place again.

Being pushed by her coach, close friends, and husband to go straight for the IFBB, as she was proving to be a top competitor in the NPC division. Marissa stepped on stage in 2014 and took home 2nd place in the IFBB, which rightfully secured her with the Pro card.

Marissa now continues to work with her company in helping others prepare for their first bikini show. She want’s to make the process as fun and enjoyable as possible for each person, along with helping them to make the right choices through their cutting edge information.

“I would do legs hard and really heavy and my quads grew out of control.”


Building Stong Legs

Marissa is only 5ft tall, so when she trains her legs, she really gains muscle fast. Her good genetics and work ethic means she can build muscle relatively fast.

So much so, that 8-12 weeks before one of her competitions she had to completely stop leg training altogether as they were growing too much. Marissa had to switch to cardio on her legs days to reduce the size.

Marissa’s know for having great legs, this is one of her features she admires the most. She notices her best results come from doing light to moderate weight with higher repetitions.


As for cardio and fat loss, Marissa prefers HIIT cardio as it’s the most effective for her. She says that it helps her to retain hard earned muscle whilst shredding the fat.

“This has been the most effective for me. It has helped me lean down while keeping a substantial amount of muscle.”
