The story

Calum Best’s 8-Week Transformation with BTX

For years, Calum Best was known for his high-energy, fast-paced lifestyle. As a public figure, his image often revolved around being a party boy, moving from one event to the next without much structure when it came to fitness and well-being. However, as time passed, he realised that he needed a change—not just for his body, but for his overall health, mindset, and longevity. He knew he needed expert guidance, structure, and accountability, which is why he turned to BTX.

The Turning Point

Recognising that he needed a structured approach to fitness and nutrition, Calum committed himself fully to an 8-week transformation programme at BTX. With the support of our elite coaching team, we developed a bespoke programme designed to strip fat, build lean muscle, and enhance overall fitness. The goal was never just about dropping weight—it was about sculpting a strong, athletic, and sustainable physique that would keep him in top form well into his 40s and beyond.

The Results: 100kg to 94kg in 8 Weeks

Over the course of 8 weeks, Calum’s transformation was remarkable. By staying disciplined with his training and following a nutrition plan built around his body’s needs, he successfully dropped 6kg, going from 100kg to 94kg while preserving muscle definition. Unlike typical weight loss programmes that focus solely on shedding kilos, our approach ensured that he built strength, endurance, and maintained an aesthetic, well-balanced physique.

But more than the numbers on the scale, the biggest transformation happened mentally. With the right structure in place, Calum found consistency and accountability, something he had previously lacked in his routine. His training evolved from being just another workout to a focused, goal-driven system that delivered real, lasting results.

The Training & Nutrition Approach

  • Tailored Resistance & Functional Training: To create an athletic, sculpted physique, we designed a programme that combined strength training, hypertrophy work, and functional movements to keep him lean, strong, and conditioned.
  • Progressive Overload & Adaptation: His programme was constantly adjusted to ensure he was progressing each week, allowing him to burn fat efficiently while increasing muscle tone.
  • Structured Nutrition Plan: By focusing on whole, nutrient-dense foods, tracking macros, and ensuring a balance of high protein, healthy fats, and controlled carbs, we created an approach that fuelled performance while promoting fat loss.

The Outcome: Fitter, Stronger, Happier

Now in his 40s, Calum Best is in the best shape of his life. His transformation is not just about looking good—it’s about feeling stronger, more confident, and happier than ever. This isn’t just a temporary change, but a lifestyle shift that he can maintain for years to come.

His journey proves that with the right guidance, structure, and accountability, true transformation is possible—at any stage in life. At BTX, we don’t just help you train—we help you build the best version of yourself.
