Last December 2024 Grisonscollaborator of ‘La Revuelta’, left all of Spain completely speechless with his great transformation. dAfter several months of the Men’s Health Challengethe beatboxer made it clear that with Effort, perseverance and hard work can get you anywhere.
And although Grison already started with a good base, the training of Aarón Santos, our technical director and fitness expert, made the television player become very very strong. “He trains with great intensity, following the plan in detail and does not rest either in the gym or at home.“said the sports professional.
After learning how to take care of yourself and how to get the most out of trainingGrison did not hesitate for a moment to continue with the sport. It’s been 12 months since he showed off his biceps and abs on the cover of MH, but he’s still going strong. And not only with exercise, but also with diet.
In addition to commenting on ‘La Revuelta’ how he continues to train (the other day he said that he even has muscle spasms when he exercises a lot), the TVE collaborator has been showing on social networks some of the physical movements he makes in his routine. AND He did it without a shirt to show off again the very defined muscles he has.
It’s clear that far from losing form, Grison has continued to perform superbly and still not gaining weight. And with our Challenge He lost almost 10 kilos of fat, He gained lean muscle and shrank to reduce his abdominal circumference by 8 centimeters.

Grégory “Grison” Dubois, a French fitness enthusiast and former amateur bodybuilder, captured international attention in 2022 when he undertook the Men’s Health 12‑Week Challenge. The challenge,organized by the global lifestyle magazine Men’s Health,is a structured program that combines progressive resistance training,periodized nutrition plans,and lifestyle coaching to help participants achieve measurable improvements in muscular hypertrophy,strength,and overall body composition.
Following the initial 12‑week regimen, Grison documented his progress and continued the program for another full year, applying the same principles with incremental adjustments. His transformation was featured in a follow‑up article titled “One Year Later: Grison’s Muscle Transformation After the Men’s Health Challenge,” which highlighted his dedication to consistency, refined training techniques, and adaptive nutrition strategies. The case study has since become a reference point for readers seeking evidence‑based approaches to long‑term muscle growth.
The Men’s health Challenge itself originated in 2015 as part of the magazine’s “Blueprint for a Better You” series. It was designed to demystify scientific training concepts for the general public, offering a standardized protocol that could be adapted to various fitness levels. Over the years, the program has evolved to incorporate modern periodization models, individualized macro‑tracking, and psychological support mechanisms, making it a comprehensive lifestyle overhaul rather than a short‑term gimmick.
Grison’s year‑long journey exemplifies how the challenge’s foundational pillars-progressive overload, nutrition periodization, and recovery optimization-can be scaled for sustained hypertrophy. His story has inspired countless readers to view fitness as a marathon rather than a sprint, emphasizing the importance of data‑driven adjustments and realistic goal setting.
