5 Weider Principles For Personal Growth and Development

Hi there! I’m Gregg Swanson, and I’ve spent over 20 years helping individuals and teams achieve mental strength and resilience. Having survived an avalanche and excelled in CrossFit competitions, I know firsthand how to push through life’s toughest challenges. I’m excited to share the tools I’ve used to overcome adversity and help you do the same.

I’ll be honest—when I first stumbled across Joe Weider’s bodybuilding principles, I had no idea how much they’d end up transforming my entire approach to personal growth and development. At first glance, they seemed like something purely for gym junkies and bodybuilders, right?

But the more I dug into these principles, the more I realized that the foundations Weider laid out for building physical strength can be applied to mental strength, too. The way we train our bodies is eerily similar to the way we can train our minds and spirits to reach our peak potential.

Let me walk you through how these physical strategies shifted my mindset, challenged my habits, and helped me grow into a stronger version of myself.

Here Are The 5 Weider Principles For Personal Growth and Development

The Power of Progressive Overload in Life

One of the first things that caught my eye was Weider’s Progressive Overload Principle. It’s this idea that you need to constantly increase the intensity of your workouts to see progress. You start small, adding a little more weight each time, and over time, you become stronger. Simple, right?

Well, I began to think about this in terms of personal growth and development. What if I treated life challenges the same way? Instead of overwhelming myself with massive goals, I started taking small steps. If I wanted to become better at public speaking, I wouldn’t jump into a keynote at a major conference. No, I’d start by speaking up more in small meetings. Each time, it was a bit uncomfortable, but not impossible—just like adding a tiny bit more weight to the barbell. Over time, that “weight” didn’t feel so heavy. My confidence and skill set grew because I embraced the idea of incremental progress.

So, if you’re feeling stuck, try adding just a bit more “weight” to your daily routine. Challenge yourself with slightly harder tasks than yesterday. It’s in these small, manageable steps that the biggest growth happens. Trust me.

Avoiding Life’s Plateaus with Muscle Confusion

I don’t know about you, but there have been so many times when I felt like I’d hit a plateau in my personal growth. Whether it was in my career, relationships, or even just trying to build better habits—there was a point where I felt like I was going through the motions without seeing any real progress.

That’s when I remembered the Muscle Confusion Principle. In bodybuilding, it’s all about keeping your muscles guessing by changing your workouts regularly. If you keep doing the same exercise over and over again, your muscles get used to it, and you stop growing. It made me realize—wow, I was doing the exact same thing in life. I was stuck in a routine that no longer challenged me.

So, I started switching things up. Instead of following the same old path in my work, I took on projects outside of my comfort zone. I joined a mastermind group and collaborated with people in different industries. That shift—just like mixing up workouts—forced me to think in new ways, learn new skills, and reignite my passion for what I was doing.

If you feel stuck or stagnant, maybe it’s time to “confuse your muscles.” Take on a new challenge or hobby. Maybe even read a book on a completely different subject. Sometimes, shaking things up is all it takes to jumpstart your personal growth and development.

The Importance of Prioritizing Weaknesses First

Another gem from Joe Weider that resonated deeply with me was the Muscle Priority Principle. Weider advocated for training your weakest muscles first because they require the most energy and focus. This totally hit home for me, because in my personal development journey, I’d been avoiding the things I wasn’t good at.

For the longest time, I shied away from areas where I felt less confident—whether it was networking (I’m naturally introverted) or learning new tech tools that were vital for my job. But once I embraced this principle, I realized I needed to tackle these weak points head-on. I made it a point to start my day by working on the things I wasn’t good at. First thing in the morning, when I had the most energy, I’d dive into whatever made me uncomfortable.

And let me tell you, it worked wonders. Focusing on my weaknesses didn’t just improve those specific skills; it had a ripple effect, boosting my overall confidence. So, take a hard look at the areas where you might be struggling in your personal growth and development. Attack those first. You’ll find that once you strengthen those weaknesses, everything else in life starts to fall into place more smoothly.

Tuning Into Your Instincts

Weider also championed the Instinctive Training Principle, which encourages bodybuilders to listen to their bodies and adjust their workouts accordingly. This one was a real game-changer for me in terms of personal growth and development. In today’s fast-paced world, it’s easy to follow someone else’s formula for success—whether it’s a popular morning routine, a productivity hack, or a diet plan. But here’s the thing: what works for others might not work for you.

I remember trying to follow this rigid productivity schedule I found online. It worked for a week or two, but eventually, I hit a wall. I felt drained and disconnected from what I was doing. Then it hit me: I needed to pay attention to what my body and mind were telling me. Just like in training, where some days you push harder and others you rest, personal growth requires tuning into your own rhythms.

When I gave myself permission to adjust based on how I felt, I started making more meaningful progress. I realized that personal growth isn’t about sticking to someone else’s script. It’s about understanding when to push yourself and when to give yourself some grace. So, listen to your instincts. Adjust when necessary. There’s no one-size-fits-all path to personal development.

Pushing Beyond Comfort with Giant Sets

One of the most intense Weider principles is the Giant Sets Principle, where you string together 4-6 exercises with little to no rest in between. The idea is to overwhelm the muscles and force them to adapt under stress. At first glance, it seems brutal—and it is—but it’s also incredibly effective.

This principle reminded me of a time when I took on way too many responsibilities at once. I’m talking about juggling a major work project, trying to build a side hustle, and working on my fitness all at the same time. It was overwhelming. But something magical happened—I started to adapt. The pressure pushed me to get super efficient with my time, focus on what really mattered, and let go of the distractions.

While I wouldn’t recommend living in a constant state of stress, there’s something to be said for periods of intense focus. If you’re serious about personal growth and development, there will be times when you have to push yourself beyond your comfort zone—when you have to take on more than you think you can handle. And it’s in those moments that you grow the most.

Final Thoughts on Personal Growth

So, here’s what I’ve learned: personal growth and development is a lot like bodybuilding. It takes consistent effort, self-awareness, and the willingness to push beyond your limits. You can’t just do the same thing day in and day out and expect results. Whether you’re aiming to improve your career, build better relationships, or strengthen your mindset, it’s all about applying these principles to your life.

Start small, challenge yourself, listen to your instincts, and most importantly, never stop growing. Personal development isn’t about perfection—it’s about progress. Keep moving forward, even if it’s just one step at a time. You’ll be amazed at where you can go.
