Scaling assistant · beta
Use a transparent starting point for common substitutions in Murph. The goal is to preserve the time domain, movement pattern where practical, and training intent—not to claim that every movement is identical.
Start with movement quality.
If pain, injury, unfamiliar equipment, or loss of control is part of the decision, pause and get a qualified coach or clinician’s guidance rather than relying on this tool.
How this beta works
Cardio substitution
Distance on a bike or rower changes with model, resistance, terrain, and athlete skill. Enter your normal run pace; this tool protects the expected time interval instead.
Choose available equipment
Suggested starting prescription
Row for 2:00
Cyclical aerobic work with posterior-chain contribution.
Changes impact and running mechanics; maintains a comparable work interval.
This beta is an educational starting point, not medical or individual coaching advice. Record the modification used with your result. Scaling principles are informed by CrossFit: Substitutions and hitting the stimulus.
The story
Navy Lieutenant Michael Murphy was killed in Afghanistan on June 28, 2005, during Operation Red Wings. He exposed himself to enemy fire to call for help for his team, ultimately sacrificing his life to save others. He was posthumously awarded the Medal of Honor for his heroic actions. The workout was one of his favorites.
Execution notes
Simple reminders that can help you stay composed when the work starts to accumulate.
Equipment matters: Use cross-training shoes, NOT weightlifting shoes - the heel and weight impair running performance
The "Cindy Plus" method (20 rounds of 5-10-15) is proven most effective for most athletes
Warm up for 15 minutes minimum - this is a long, demanding workout that requires proper preparation
Hydration strategy: 16-20oz water 2 hours before, 8oz 30 minutes before, sip water every 3-4 rounds
Grip management is crucial: alternate grip, use chalk every 5 rounds, hang from bar between rounds to decompress spine
Post-workout recovery: 16-24oz water with electrolytes, protein + carbs (3:1 ratio) within 30 minutes
