Intro: RB100 isn’t just about reps — it’s about consistency. The 100 Days of Fitness Challenge is a cornerstone of this platform. The rules are simple: move your body every day for 100 consecutive days.

No max lifts required. No gym memberships. Just consistent action, done daily, and logged. The power of the streak is real.


How It Works

  • Duration: 100 days, no skips
  • Daily requirement: At least 20 minutes of intentional movement
  • Format: Anything counts — walking, lifting, swimming, yoga, sport, stretching
  • Tracking: Use our printable or digital RB100 Tracker to stay accountable

What Counts?

  • A 30-minute weights session? ✅
  • 45-minute walk with the dog? ✅
  • 20-minute yoga flow before bed? ✅
  • Intense sport or mobility? ✅

If it’s movement, it counts.


Why It Works

  • Builds momentum through daily discipline
  • Reinforces identity change (“I’m someone who trains daily”)
  • Generates measurable progress over time
  • Supports mental clarity and energy

Tips for Success

  • Lay out clothes the night before
  • Schedule your movement like a meeting
  • Find an accountability partner or log on socials with #RB100Challenge
  • Use variety: weights, walking, bodyweight, mobility, sport
