Why You Should Have Started Rucking Yesterday

I’ve been rucking since 2014 before it becale a national phenomenon back when I was grinding through contest prep for competitive bodybuilding. Fast forward to 2026, and I’m still rucking 3-5 days a week—hell, I even completed a 50K mountain ruck challenge. For me (and a lot of other Apex predators out there), rucking is the ultimate conditioning and capacity tool. It’s cardio with a backbone—literally. Unlike traditional endurance training that eats away at muscle, rucking actually helps preserve lean mass and, in some cases, even build it.

​So, if you’re looking for a brutally effective way to level up your cardio, build real-world strength, and burn fat—without wrecking your joints or sacrificing muscle—rucking is the answer. It’s one of the most underrated training methods out there, even though it’s been a military staple for decades. Top tier warfighters ruck daily and use it as their main practical conditioning tool.

What the Hell is Rucking?

Simple: rucking is walking with a weighted backpack. That’s it. Sounds too easy to be effective? Think again. Load up a pack, walk some miles, and suddenly a basic human movement turns into an absolute workhorse of a workout. The military has been using rucking for decades to forge durable, battle-ready soldiers. Now, civilians are catching on—and for damn good reason.

Why You Should Start Rucking Today
  1. It’s Stupid Simple – No gym, no machines, no nonsense. Just grab a backpack, throw in some weight (bricks, books, or actual ruck plates if you’re fancy), and start moving.
  2. Builds Strength Without Wrecking Your Joints – Running beats up your knees. Rucking? Not so much. You still build muscular endurance, but without the impact. Your legs, core, and back get stronger without the wear and tear.
  3. Massive Cardio Benefits – Your heart rate goes up more than regular walking, but you’re not gasping for air like you would be with sprinting or distance running. It’s sustainable, efficient, and incredibly effective.
  4. Burns More Calories Than Walking – Slap some weight on your back, and suddenly your walk turns into a calorie-torching session. Rucking can burn 2-3 times more calories than walking at the same pace.
  5. Develops Mental Grit – Carrying weight for miles isn’t just physical—it’s a test of mental toughness. You learn to push through discomfort, and that carries over to everything in life.
  6. Works for Any Fitness Level – Whether you’re an elite lifter, a total beginner, or someone who just hates traditional cardio, rucking meets you where you’re at. Start light, progress over time, and watch your endurance and strength explode.
  7. You Can Do It Anywhere – Ruck on a trail, around your neighborhood, or even on a treadmill if you’re stuck inside. Zero excuses.
  8. You Just Look Like a Badass Doing It – And more importantly, you feel like one too.

How to Get Started
  • Get a Solid Backpack – Something that won’t destroy your shoulders. I use the GORUCK Rucker. I have both the 20 liter and 25 liter. They are pricey, but if you find the same value in rucking as I do, it's a fantastic investment and they are bombproof gold-standard. . 
  • Pick Your Weight – Start with 10-20 lbs if you’re new. Over time, work up to 30-50 lbs or around 20% of your bodyweight.
  • Walk – Aim for 30-60 minutes at a brisk pace. Increase distance and weight as you get stronger.
  • Stay Consistent – Like anything else, the results come from showing up—week in, week out.

Final Thoughts

Rucking is hands-down one of the simplest, most effective ways to build strength, endurance, and resilience—all while getting outside and clearing your head. Whether you want a new tool in your training arsenal or just an excuse to move more, this is it.

Strap up, start rucking, and thank me later.

The Science Backs It Up. Studies confirm what we already know: rucking works. Research has shown that walking with weight improves muscle strength, endurance, and even oxygen uptake. A 2019 study found that a 10-week rucking program led to better muscle power and cardiovascular capacity with lower perceived exertion—meaning you get fitter, faster, and stronger without feeling like you’re dying. Rucking has even been shown to help older adults maintain muscle, making it a killer long-term training tool.

Bottom line? The science is clear. The results speak for themselves. Now, quit overthinking and start rucking.
