Margot Robbie’s physique has become one of Hollywood’s most talked-about transformations, but the training behind it defies typical celebrity fitness stereotypes.
Her longtime trainer David Higgins built her lean, athletic frame using Pilates-forward functional training rather than traditional bodybuilding methods.
From rollerblading in Barbie to performing stunts as Harley Quinn, Robbie’s training adapts to each role while maintaining core principles of movement quality and injury prevention.
What makes her approach particularly effective is how it prioritizes function over aesthetics—yet delivers both.

The Man Behind Margot’s Transformation
David Higgins isn’t your typical celebrity trainer throwing around kettlebells and counting Instagram followers. Based in London, he’s developed a hybrid methodology that blends classical Pilates, myofascial release, postural analysis, and performance conditioning.
His client roster includes Daniel Craig and Jonathan Rhys Meyers, but his work with Robbie has become his most visible success story. The philosophy driving her program is deceptively simple: when muscles fire correctly and posture is optimal, aesthetic results follow naturally.
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
Higgins doesn’t chase the look. He chases function, and appearance becomes a byproduct.
Training for Barbie: Precision Over Power
Preparing for Barbie required Robbie to develop upper body definition without bulk—a delicate balance that traditional weight training often overshoots. Higgins accomplished this through reformer Pilates and high-repetition resistance work targeting stabilizer muscles.
Months before filming, Robbie relearned how to rollerblade, incorporating balance and ankle stability drills into her sessions. Dance choreography added cardiovascular conditioning and coordination challenges that complemented the strength work.
The Barbie aesthetic demanded shoulders, arms, and back that looked toned rather than muscular. Achieving this required surgical precision in exercise selection and volume management.
Harley Quinn: Power Meets Agility
For her Harley Quinn roles in the Suicide Squad franchise, training shifted toward agility, explosive power, and stunt preparation. This iteration included conventional strength movements—deadlifts, squats, and pushing patterns—alongside gymnastics-adjacent bodyweight control.
Fight choreography demands both convincing appearance and actual physical capability. Robbie needed to execute sequences safely while looking like someone who could genuinely handle herself in combat.

The contrast between Barbie and Harley Quinn training demonstrates program versatility. Same foundational principles, dramatically different emphasis depending on role requirements.
Pilates: Not What You Think
Robbie’s Pilates work bears little resemblance to gentle mat classes at local studios. Higgins uses reformer-based Pilates with significant spring resistance, loading muscles while demanding precise neuromuscular control.
This builds deep stabilizer strength in core, hips, and shoulder girdle that conventional gym training frequently misses. It also develops the long, lean muscle appearance characteristic of dancers and gymnasts.
Think of reformer Pilates as resistance training disguised as flexibility work. Spring tension creates load, unstable positions demand stabilization, and precise movement patterns ensure muscles fire correctly.
Training Frequency and Session Structure
During production preparation, Robbie trains five to six days weekly. Once filming begins, frequency drops to three to four sessions to accommodate demanding shooting schedules.
Sessions typically run 60-90 minutes and follow consistent structure:

- 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
- Mobility and activation: Priming nervous system and joints for work ahead
- Main training block: Pilates, strength work, or sport-specific conditioning depending on current focus
- Active cooldown: Myofascial release and stretching to manage recovery
Morning sessions are preferred when schedules allow. Robbie has noted that early training sets her mental state for the entire day—an underrated benefit of consistent exercise timing.
The Pragmatic Mindset
Robbie’s approach to fitness is refreshingly honest. She doesn’t claim to love gym sessions inherently but appreciates what training provides: energy, mental clarity, and physical capability to perform her own stunts when possible.
This attitude—training as tool rather than identity—may be the most sustainable approach to long-term fitness. It removes emotional attachment from individual workouts while maintaining commitment to the process.
Years of consistent training matter infinitely more than any single exercise or program. Robbie embodies this principle.
Nutrition: Performance Over Restriction
Robbie’s nutritional strategy avoids extreme diets and food group elimination. Instead, she focuses on high-quality protein for muscle recovery, adequate carbohydrates for training fuel, and vegetables for micronutrients.
Typical daily intake includes protein at every meal—eggs, chicken, salmon, Greek yogurt. Complex carbohydrates come from quinoa, sweet potato, and whole grain bread. Healthy fats arrive via avocado, salmon, and nuts.

During film preparation, she avoids alcohol and processed foods but doesn’t follow rigid meal timing or obsessive tracking. Eating supports performance, and aesthetics follow as consequence rather than direct target.
Key Training Components
Several exercises appear consistently across Robbie’s programs regardless of specific role preparation:
Reformer Footwork Series
Pilates reformer footwork builds quad, glute, and calf strength while developing deep core stability. Spring resistance loads legs through multiple positions, teaching muscles to fire in coordinated patterns.
Single-Leg Romanian Deadlifts
This movement develops hamstring strength and hip stability simultaneously. Balance demands force core engagement, making it efficient compound exercise that addresses multiple training goals.
TRX Pike to Plank
Suspension training adds instability to core exercises, forcing shoulders and hips to stabilize while moving through challenging positions. This builds functional strength applicable to stunt work and everyday movement.
Lateral Band Walks
Hip abductor strength prevents knee injuries and builds glute medius—critical for both athletic performance and aesthetic hip development. Simple but brutally effective when performed correctly.

- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Push-Up Variations
Rather than barbell bench pressing, Robbie develops chest and tricep strength through bodyweight push-up variations. This maintains shoulder health while building functional pressing strength.
Progressive Overload Without Ego
Higgins applies progressive overload through multiple variables beyond simply adding weight. Increased time under tension, reduced rest periods, improved movement quality, and enhanced range of motion all represent progression.
This approach allows continuous advancement without the joint stress that heavy barbell work can create. It also prevents the bulky appearance that maximal strength training sometimes produces in women.
Recovery as Training Component
Myofascial release and active recovery work aren’t afterthoughts in Robbie’s program—they’re integrated training components. Higgins uses foam rolling, targeted stretching, and massage to manage tissue quality and prevent compensatory movement patterns.
Poor recovery leads to poor movement quality, which leads to injury and diminished results. Prioritizing tissue management allows higher training frequency and intensity over years.
The Longevity Perspective
What separates Robbie’s approach from typical celebrity crash fitness programs is its sustainability over decades. Higgins designs programming that Robbie can continue at 50, 60, and beyond with minimal modification.

Movement quality emphasis protects joints. Pilates foundation maintains core integrity. Functional strength transfers to real-world activities rather than existing solely for gym performance.
This isn’t training for next month’s photoshoot. It’s building physical capability and resilience for life.
Application for Regular People
Most people lack Robbie’s access to elite trainers and flexible schedules, but her program’s core principles apply universally:
- Prioritize movement quality over weight moved
- Build deep stabilizer strength through Pilates or similar modalities
- Train consistently rather than intensely but sporadically
- Adapt programming to current goals while maintaining foundational work
- Eat to support performance rather than restrict obsessively
Three quality sessions weekly following these principles will produce better long-term results than six mediocre gym visits chasing the latest fitness trend.
Robbie’s physique comes from years of consistent, intelligent training—not genetic lottery or extreme measures. That’s simultaneously the disappointing and empowering truth about sustainable fitness transformation.
