The 40% Rule.
A rule by David Goggins.
You know that feeling when you’re working out—maybe you’re running, lifting weights, or tackling an intense task—and suddenly, every muscle or ounce of willpower is screaming, “Stop! That’s enough”? Your mind starts making excuses, telling you it’s time to quit. Most people would stop right there. But what if I told you that at that moment, when you think you’ve hit your limit, you’re actually only at 40% of what you’re truly capable of?
This is the essence of David Goggins’s 40% Rule.
Who is David Goggins?
David Goggins is known as one of the world’s toughest and most disciplined men. He’s a retired Navy SEAL and motivational speaker who is jacked with a story defined by pushing past unimaginable physical and mental limits. Growing up, Goggins faced trauma, poverty, and racism, which fueled his drive to transform his life. He went on to become a SEAL and complete feats that seem impossible to most, like running ultra-marathons, completing ultra-triathlons, and holding a world record for the most pull-ups in 24 hours. Goggins has built his life on the idea of taking full responsibility for his limits—and then shattering them.
What is the 40% Rule?
The 40% Rule is simple but powerful: When your mind and body are telling you that you’ve hit your limit, you’ve really only reached 40% of your actual capacity.
Goggins tells us that our minds are wired to seek comfort, which often leads us to quit far sooner than necessary. This rule is a reminder that we’re capable of much more than we realize.
The rule teaches that when you feel you’re at your limit, you’re likely only using a fraction of your potential. Pushing past this point isn’t easy, but it’s where real growth and mental toughness are built. Goggins uses this rule to fuel his training, reminding himself that his body and mind can go much further.
How to Apply the 40% Rule to Your Life
You don’t have to be a Navy SEAL to apply the 40% Rule. Here are a few pointers:
Challenge Yourself Daily
Whether it’s in the gym, at work, or in your personal goals, start pushing yourself when you feel that urge to quit. If you’re running and feel tired at mile two, challenge yourself to go to mile three. The goal isn’t to push recklessly but to get comfortable with discomfort. Each time you do this, you’re building resilience and expanding your limits.Build Mental “Calluses”
Goggins talks about “callusing the mind.” Just as physical calluses protect our hands from discomfort, mental calluses protect our mind from giving up. The key is to expose yourself to controlled discomfort regularly. Take a cold shower, wake up early, or tackle a difficult task without procrastination. The more you train your mind to endure, the stronger it becomes.Use Micro-Goals to Keep Moving
When faced with a difficult task, break it down into small, manageable steps. For example, if you’re running and feel like stopping, commit to just ten more steps. If you’re working on a big project, focus on the next 30 minutes instead of the entire task. These micro-goals help you keep going, one step at a time, even when you want to quit.Self-Reflection and Accountability
Goggins uses what he calls the Accountability Mirror. Every day, he takes an honest look at his own actions and identifies where he can improve. Hold yourself accountable—track your progress, acknowledge areas where you’ve fallen short, and commit to pushing harder tomorrow.
Training Body and Mind to Improve Yourself
Physically: Train your body by incorporating workouts that challenge you beyond your comfort zone. Don’t always go for the easy, routine workouts.
Add in sessions that push you to exhaustion, safely increasing your limits little by little. Your body adapts to what it’s used to, so to improve, you need to give it new challenges.
Mentally: Training your mind is equally crucial. Practice positive self-talk and visualization. Goggins uses these techniques to keep himself grounded and focused, especially during grueling tasks.
Visualize the finish line or the end result, and tell yourself that you’re only at 40% when you want to quit.
The Payoff of the 40% Rule
When you push past your limits, you build grit, confidence, and the realization that you’re capable of much more than you thought. The 40% Rule doesn’t just apply to workouts—it applies to every area of life where we encounter resistance. Overcoming these mental barriers is how we grow, and it’s how we get closer to the best versions of ourselves.
The next time you feel like you’ve reached your limit, remember: that’s just 40%. Keep pushing—you’ll be amazed at what you’re truly capable of.
