Nikki kicked off her fitness journey with training sessions, gradually transitioning to weightlifting despite initial struggles. Over time, her progress became evident to all, both in mind and body.

Recognizing her potential, the gym’s coach began working closely with her, guiding her from lighter weights to heavier ones and incorporating more cardio exercises. Nikki developed a passion for exercise, leaving behind the allure of parties and alcohol.

Encouraged by friends and her coach, Nikki took a leap and entered her first bikini show at 21. Though victory eluded her, the experience left her feeling empowered and fueled her determination to train harder and participate in more competitions.

After her first bikini contest, Nikki received multiple offers for modelling, and so launched her career as a fitness model. While her career as a bikini competitor has somewhat collapsed as she hasn’t managed to win any competitions, her career as a fitness model became quite successful, and she has since become a sought-after model.

Nikki has posed for numerous fitness magazines, and has appeared on their cover pages, and in numerous commercials for some worldwide known clothing brands. She served as an ambassador for the Cellucor supplement company and has also posed for the GymShark fitness clothing company.

She is a YouTuber as well, as she launched her channel on 17 January 2014, and there are currently more than 697,000 people subscribed to it, it also counts more than 115 million views of all her videos combined, which generally relate to her everyday life, while she also gives tips and advice to all those people who would like to start exercising.

Nikki’s training and dieting

Nikki has five training sessions per week and splits these into two days of upper body workouts, and three days of leg workouts. She does cardio as well, but doesn’t have certain days on which she does it – they come when she feels she needs them.

Some of her favorite exercises include step-ups, squats, and lunges as these are all very important for her legs and glutes which are her favorite part of her body – she has shared her entire workout routine on the greatestphysiques.com website.

Nikki follows the ‘If it Fits Your Macros’ (IFFYM) diet – this allows the person to eat whatever they want, but in limits. She eats five to six times per day while breakfast is her favorite meal – she mostly eats eggs, bacon, oatmeal, waffles, and chicken.

When it comes to supplements, Nikki is only taking Vitamin C and Biotin, and occasionally branched-chain amino acids (BCAA).

Personal life and relationships

Nikki is very secretive when it comes to her love life, as she hasn’t really shared with the public any details regarding her past and present affairs.

Back in 2014, the model found herself entwined in a romance with Christian Guzman, a connection sparked amidst the intensity of a shared bodybuilding competition. Their paths intertwined further when Guzman stumbled upon Blacketter’s online presence, leading to a blossoming friendship.

Guzman often made appearances in her YouTube videos, their affection apparent to viewers. However, despite the initial promise, their love story unraveled, and by 2015, they found themselves drifting apart, their separation occurring just days before their respective birthdays, with Christian initiating the breakup.

Speculations have surfaced online suggesting Nikki’s sexual orientation might lean towards being a lesbian. There’s no proof of that, though.

A chance encounter at a bustling Los Angeles nightclub brought Nikke face to face with Miles Sullivan, introduced through the common thread of Sterling, a mutual friend.

Their meeting transpired in 2017, with their first date in March. Initially cautious about diving into anything too serious, Nikke approached the budding relationship with trepidation.

Yet, as they shared moments and built memories, the gravitational pull towards each other grew stronger. Sullivan, a proprietor of a digital marketing firm nestled in the vibrant hub of Venice Beach, California, also dabbled in crafting rap melodies on SoundCloud.

Symbolizing their bond, the couple opted for matching wrist tattoos, sealing their commitment. Alas, their storybook romance encountered stormy seas, and by June 2018, they parted ways.

Since then, it is believed that Nikki is single.
