Anyone who has watched a survival expert like Ray Meara or Bear Grylls knows the Rule of 3 for survival: you can survive approximately 3 hours in an extreme environment without shelter, 3 days without water, and 3 weeks without food. This understanding of survival directly correlates with developing Mental Toughness.
This ruthless survival principle applies directly to the gym. Our goal at CrossFit Chiltern is to prepare you for the unknown and unknowable, which means eliminating the comfort-seeking excuses that kill resilience and hold back your fitness, ultimately fostering your Mental Toughness.
Here is the Rule of 3 for CrossFit Survival—the three areas where you must stop making excuses and start building true Mental Toughness:
1. The 3 Hours Without Shelter (Embrace the Discomfort)
This rule is about environment. A person can survive for approximately three hours in an extreme environment without shelter, but we see it every day: athletes who scream for the shutter door to be opened 30 seconds into a WOD, the girl who does burpees directly in front of the fan, or the one who refuses to use any pull-up bar but their “lucky” one.
- The Problem: You are creating a comfort bubble. You are training your body and mind to only perform under ideal, perfect conditions.
- The Coaching Fix: Toughen The F* Up.** CrossFit is about finding your limits and pushing through. If you can’t take the heat, you can go down to the local leisure centre and get soft. Embrace the uncomfortable. Use the highest or lowest pull-up bar. Skip the mat for burpees. Train with a shirt on. If you want to train for life, you must be able to perform regardless of the environment.
2. The 3 Days Without Water (Stop the Drink Break Stall)
This rule addresses the most common mid-WOD excuse: the drink break.
- The Problem: This is for the athlete who thinks it’s okay to take a drink 5 minutes into a 20-minute workout, or worse, 2 minutes before the end. This is rarely a physiological need; it is a rest stall.
- The Coaching Fix: There isn’t a single CrossFit class WOD under 30 minutes that needs water mid-WOD. Hydrate consistently before and after. You are not going to die of dehydration mid-WOD. The moment you take that long drink break, you compromise the high-intensity stimulus, and you signal to your mind that quitting is an option. Sip strategically between movements if absolutely necessary, but otherwise, push the pace.
3. The 3 Weeks Without Food (Master the Mid-Afternoon/Late night Snack)
This rule applies to hunger management. We are incredibly resilient, yet we panic if we miss a scheduled snack.
- The Problem: This is for those of us who constantly reach for the mid-afternoon or late-night snack. Most likely, we’re not truly hungry; we’re bored or habitual. This reliance on constant feeding prevents the body from becoming metabolically flexible.
- The Coaching Fix: Break the habit! You can last three weeks without food, so you are going to be fine waiting three hours between meals. Focus on high-quality, protein-anchored meals that provide true satiety (see our blog on Mindful Eating). Use the HALT Check (Am I Hungry, Angry, Lonely, or Tired?) to diagnose the real craving. Don’t let boredom dictate your diet.
