Two brothers who used to rock visible abs found themselves in vastly different shape after building careers as DJs, launching a beer brand, and diving deep into the fast-food business.
Their 90-day transformation journey wasn’t just about losing weight—it culminated in competing in a grueling Hyrox fitness race.
The results they achieved reveal exactly what’s possible when lifestyle changes meet consistent effort, even with packed schedules and business obligations.
Rob and Arno, successful DJ brothers who also own multiple businesses, committed to a complete body transformation despite their hectic lives.

Starting Point: Two Brothers, Two Different Challenges
On day one, Rob weighed 181 pounds at 21% body fat, while his brother Arno tipped the scales at 230 pounds with 29% body fat.
I’m a very body positive person, but I went too far.
Their goals reflected their different starting points. Rob targeted seven pounds of fat loss with improved endurance, while Arno set his sights on an ambitious 44-pound drop.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Both received custom workout programs with 24/7 coaching support, recognizing that most beginners struggle to push themselves effectively without guidance.
The First 30 Days: Establishing New Habits
The initial weeks brought rapid changes for Arno, who created an ideal environment for transformation by building a home gym and getting his girlfriend to join the challenge.
He eliminated temptation by stocking only healthy foods and embraced evening walks as part of his new routine.
Hello, we’re on a walk after dinner. We’re going to walk like 45 minutes. It’s our first time we walked a block.
Rob faced different obstacles. As a father, DJ, business owner, and content creator, he juggled DJing until 3 AM while simultaneously opening a fast-food restaurant.
His schedule made consistency challenging, requiring adjustments to his training plan that better accommodated his lifestyle.
The 30-Day Results Revealed Stark Differences
Arno’s dedication paid off dramatically. He dropped from 230 pounds to 207 pounds—a 22-pound loss in just 30 days.

- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
My planning in my head when I started this challenge was lose 10 the first 30 days, lose five every 30 days after. So, it’s 20 in total.
Rob’s results were more modest—dropping from 181 to 178 pounds, losing just 3.3 pounds during his busiest month ever.
Rather than disappointment, this became fuel for the remaining 60 days.
Days 31-60: Finding Sustainable Solutions
The second phase brought important innovations. Rob implemented “SOS training sessions”—quick 40-minute workouts designed for busy schedules.
These sessions included full-body warm-ups followed by rowing variations for back development and horizontal pushing movements adjusted to his strength level.
Sometimes you just don’t have time to go to the gym.
Rob invested in home equipment including adjustable dumbbells and a pull-up bar positioned strategically near the bathroom.
The easier you make exercise access, the less likely you’ll skip workouts.

Rob’s Grocery Shopping Strategy
Rob shared his simplified approach to nutrition that made consistency possible:
- Fruit foundation: Bananas, blueberries, and strawberries for natural energy
- Volume eating: Greens and cucumbers that fill you up with minimal calories
- Protein-rich pre-made meals: Chicken-based options for time-crunched days
- Morning routine: Banana paired with pre-made meals for consistent breakfast
The biggest life hack I felt is greens, cucumber. Almost no calories, but it fills up.
While cooking your own meals provides the most control, these convenient options proved far superior to fast-food alternatives.
Arno Hit a Plateau
Around day 60, Arno experienced what many dieters face—his weight stalled at 198 pounds.
Okay, I gained weight. Like 0.5 kg, and it’s not going down. I actually know why. Cuz I got like nonchalant and like I bought everything of food and the workout is all chill.
His coach reframed this positively—getting comfortable with food choices shows a healthy relationship developing. However, with weight loss goals remaining, Arno returned to more precise food weighing and tracking.
The Final 30 Days: Vacations and Festival Season
The last stretch presented serious challenges. Both brothers took separate vacations during this critical period.
Arno traveled to Marseille with friends, facing all-inclusive temptations and alcohol.

There’s like a where you need to choose. You enjoy with the boys or you get bored.
Despite indulging, Arno convinced his friends to join morning runs, demonstrating his commitment hadn’t wavered.
Rob attended an all-inclusive resort but stuck to his nutrition plan, choosing protein and vegetables over readily available pizza, pasta, and desserts.
Festival Season Tested Rob’s Resolve
With 50 DJ shows booked for summer, Rob faced constant temptation at festivals and late-night events.
His solution? Incorporating his son into workouts, turning family time into training sessions with creative exercises using his child as resistance.
Today I’m going to do some workouts with my kids. It’s around 15 kilos, so maybe I can do some lunges, some Hyrox inspired exercises.
Day 90 Results: The Numbers Don’t Lie
After 90 days of ups, downs, vacations, festivals, and business obligations, both brothers exceeded expectations.
Rob’s transformation:

- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
- Weight dropped from 181 to 165 pounds—surpassing his seven-pound goal
- Lost four inches around the belly
- Maintained chest size while losing fat
- Revealed visible six-pack abs
I wanted to lose 7 kg.
Arno’s transformation:
- Plummeted from 230 to 188 pounds—a staggering 42-pound loss
- Chest measurements stayed identical, suggesting muscle preservation or even growth
- Lost seven inches around the belly
- Waist shrunk from 45 inches to 37 inches
Perhaps most impressive? Arno maintained his chest circumference despite massive weight loss, indicating he successfully preserved muscle mass throughout.
The Ultimate Test: Hyrox Race Performance
Beyond aesthetics, the brothers trained for a Hyrox competition—eight kilometers of running interspersed with eight brutal exercise challenges.
Their original time: 1 hour, 35 minutes. Their ambitious goal: finish under 1 hour, 10 minutes.
From the starting gun, the difference was obvious. Where they previously walked between stations, they now ran consistently.
Each challenge station—ski erg, sled push, burpees, rowing, farmer’s carry, lunges, and wall balls—was completed significantly faster than 90 days prior.

There was no walking. No walking.
Their final time? 1 hour, 12 minutes—missing their aggressive goal by just two minutes but shaving an incredible 23 minutes off their original time.
Key Takeaways From This Transformation
Several critical lessons emerged from the brothers’ journey:
Environment matters tremendously. Arno’s home gym and supportive girlfriend created conditions for success, while Rob had to creatively adapt workouts to chaotic schedules.
Consistency beats perfection. Both brothers had setbacks—festivals, vacations, business obligations—but maintained overall adherence to their plans.
Convenience is crucial. Pre-made healthy meals and home equipment reduced barriers that typically derail progress.
Volume eating works. Rob’s emphasis on low-calorie vegetables that provide satiety made calorie restriction sustainable.

Cardio cannot be neglected. Despite building impressive physiques, their Hyrox performance depended heavily on cardiovascular endurance developed through consistent running.
The Reality of Sustainable Fat Loss
Arno’s girlfriend joined the challenge and lost 33 pounds herself, demonstrating that accountability partners significantly improve outcomes.
Both brothers experienced plateaus that required adjustments—more precise tracking for Arno, better workout timing for Rob.
Their transformation didn’t require extreme measures or unsustainable restrictions. Instead, it relied on fundamental principles applied consistently over 90 days.
Beyond the Physical Changes
The brothers reported improvements extending far beyond appearance:
- Improved sleep quality
- Reduced sweating in normal temperatures
- Enhanced endurance for daily activities
- Greater confidence in social situations
Also sleeping. I also sweat less. Yeah, before when it’s this temperature, I just walk outside I was sweating.
Rob went from hiding his physique to comfortably running shirtless in public.
