UK-based YouTuber Deji (formerly ComedyShortsGamer) has recently taken up a challenge proposed by his brother and fellow YouTuber JJ (KSI). The bet? To achieve a six-pack. While Deji is no stranger to training—like JJ, he too is a boxer—the YouTuber recently revealed that he almost lost track of his fitness when he visited Las Vegas earlier this year. The 27-year-old admitted that the vibrant city’s allure led to some lapses in his workout routine and diet.

Determined to get back on track and win the bet, Deji has chosen none other than BTX Body Transformation London as his training camp. With BTX’s expertise in personalised fitness programmes and elite training methods, Deji is set to embark on a rigorous journey to achieve his fitness goals and prove his brother wrong.

Stay tuned as Deji works with BTX to transform his physique and reach peak performance, showcasing the power of dedication, expert guidance, and the right training environment.

The BTX Approach: How the Six-Pack Challenge Works

A six-pack challenge isn’t just about aesthetics — at BTX, it’s a full body composition transformation. Deji’s training at our North London studio followed the same science-backed framework we use for every client: InBody 770 scanning to establish a precise fat mass and lean muscle baseline, periodised strength training, and nutrition coaching built around realistic daily habits.

The abdominal muscles are present in virtually everyone — they’re simply not visible until body fat percentage drops below a threshold. For most men, visible abs become apparent below approximately 12-15% body fat. The process to get there isn’t a mystery, but it does require a structured approach: a consistent caloric deficit, sufficient protein intake to preserve lean mass, and progressive strength training to build and maintain muscle while fat is lost.

What BTX Clients Achieve in 12 Weeks

The six-pack challenge at BTX is a 12-week intensive programme. Clients typically lose between 5–10% of their body fat percentage over this period while maintaining or increasing lean muscle mass — as confirmed by InBody 770 rescans every four weeks. The combination of one-to-one personal training, nutrition coaching, and accountability check-ins creates the conditions for body composition change that gym-going alone rarely achieves.

If you’re based in North London and want to pursue a body transformation with the same coaching team working with Deji, book a consultation at our Hampstead studio at 529a Finchley Road, NW3.

Deji’s training at BTX also included detailed nutrition guidance focused on achieving a caloric deficit while maintaining high protein intake to preserve lean mass. The InBody 770 scans taken throughout his programme allowed the coaching team to track muscle retention and fat loss independently — ensuring the visual changes in his physique reflected real, measurable body composition improvement rather than simple scale weight loss.
