Intro: Sleep is when your body repairs, your brain consolidates learning, and your hormonal system resets. Yet it’s often sacrificed for screen time, stress, or late-night snacks.

This RB100 Challenge is a simple but powerful one: Get 100 hours of sleep over the next 10 nights. That’s an average of 10 hours per night — or at least a renewed focus on rest.


Why Sleep Matters

  • Increases recovery rate between workouts
  • Optimises hormone function (GH, cortisol, testosterone)
  • Boosts mood, memory, and emotional regulation
  • Reduces injury risk and supports muscle retention

100 Hours? Isn’t That a Lot?

  • 8 hours/night × 10 nights = 80 hours (baseline)
  • 10 hours/night × 10 nights = 100 hours (goal)
  • Include naps and early nights to help reach the target

How to Improve Sleep Quality

  • Power down devices 60 minutes before bed
  • Keep the bedroom cool, dark, and tech-free
  • Establish a wind-down routine: stretch, journal, tea
  • Track sleep with wearable tech or a notebook

Tips for Active Individuals

  • Avoid late caffeine or alcohol intake
  • Evening carbs can help promote sleep (serotonin release)
  • Sleep = your most anabolic training phase
