Challenge

Overlooked wellbeing and athletic performance due to 100+ hour work weeks, inconsistent nutrition, poor sleep patterns, work travel, and gut health issues

Client

David Burt, Former Netflix Finance Executive & Software CFO

"I had really neglected my health—both physical and mental—for quite some time. I prioritized work and family, but my health and wellness fell behind. The RAPID team gave me the ability to get back to where I wanted to be, and then I clicked over to having the confidence to do it myself."

Meet David Burt

David Burt has built a successful career optimizing business performance at some of the world's most demanding companies—from Netflix to high-growth startups. But when it came to optimizing his own health, he felt almost helpless. During years of 100+ hour work weeks, he neglected his physical and mental well-being. Despite being a former competitive athlete who ran the 100 meters in the low elevens as a teenager, he couldn't find a way back to peak performance and vitality. 

The Challenges

Like many high-achieving executives, David was facing multiple health obstacles that were holding him back from peak performance:

Extreme Work Demands: Working 100+ hour weeks as a startup CFO left no time or energy for consistent focus on health or performance

Nutritional Chaos: Zero regularity with meal timing—eating was all over the place based on an unpredictable work schedule

Sleep Pattern Disruption: Consistent 5:30 AM wake-up time but bedtime was erratic, leading to sleep deprivation

Chronic Gut Issues: Six years of irritable bowel syndrome that traditional medicine couldn't effectively address

Dehydration and Poor Recovery: Inadequate hydration and alcohol intake affected sleep quality, causing poor workout recovery

Lost Athletic Identity: Former competitive athlete struggling with the gap between past fitness levels and current reality

How Rapid Helped

David joined RAPID's Arétē program after a close friend's extensive research led to a strong recommendation. Here's what we implemented:

  1. Comprehensive Decode Process – We conducted thorough biomarker testing and food sensitivity analysis, revealing 10 critical areas needing attention
  2. Structured Nutrition & Timing – We established consistent meal schedules (7 AM breakfast, regular snacking) and identified soy as his primary food sensitivity trigger
  3. Sleep Optimization – We dialed in his sleep routine with consistent bedtimes to support his 5:30 AM wake-up schedule and addressed alcohol's impact on sleep quality
  4. Integrated Fitness Programming – We shifted focus from cardio-only to full-body strength training combined with endurance sessions tailored to marathon preparation
  5. Ongoing Support & Accountability – Weekly check-ins, Oura ring integration, and flexible program adjustments for his changing schedule and goals
  6. Holistic Stress Management – We addressed hydration consistency, nutritional timing, and recovery protocols as interconnected stress factors

Results

David achieved a remarkable transformation across all health markers:

  • Hidden Stressors Score improved from low-to-mid 60s to low 80s – a significant reduction in physiological stress
  • Completed his first marathon in 3:58 – exceeding his goal of sub-4:30 and finishing strong without injury
  • Eliminated chronic gut issues – Six years of IBS symptoms resolved through targeted nutrition and food sensitivity management
  • Achieved consistent energy levels – No more energy crashes, and sustained focus and endurance throughout demanding workdays
  • Improved family engagement – David’s kids now see him as "the best tag player on the planet” because he has boundless energy
  • Enhanced cognitive performance – He is calmer, more focused, and has better mental endurance for high-stakes executive work
  • Significant body composition changes – David reduced his body fat percentage while maintaining strength gains

Final Thoughts

David's transformation proves that even the busiest executives can optimize their health with the right systematic approach. At RAPID, we don't just address isolated symptoms—we create comprehensive, data-driven programs that fit into demanding lifestyles so high performers can excel in all areas of life. As David put it: “If you want to holistically look at your physical health, wellness, and mental health, RAPID is the best way to do it.”
