Set failure vs Non-failure: Do All Sets Need to Be Very Close to Failure? A Comprehensive 2025 Study
Share your love
Look, there’s always that one guy at the gym—tank top, gallon jug, veins bulging—swearing up and down that if you’re not leaving every set trembling, you’re just wasting your time. Like, apparently, if you don’t collapse under your last rep, you might as well have stayed home eating Cheetos. That’s the classic argument of set failure vs non-failure.
But, plot twist: a fresh study just dropped (Brandenburg et al., 2025—yeah, it’s that new), and it’s kind of flipping that whole “failure or nothing” mindset on its head. Guess what? Turns out, you don’t have to grind every set into oblivion to see your muscles actually grow. Wild, right? This really challenges how we think about set failure vs non-failure.
So, let’s break this down—the real deal about what “failure” even means, what these researchers actually found, and why it matters for regular folks like us who don’t live in the squat rack. Time to cut through the bro-science and finally clear up the confusion on set failure vs non-failure. Rambodfit got your back.

What Is Failure?
Alright, here’s the real deal: in the gym world, “failure” isn’t about sobbing on the bench because you missed a PR. It’s just hitting that wall where your muscles tap out and say, “Nope, not one more rep with good form.” That’s the basic line in the sand when it comes to set failure vs non-failure.
There’s “technical failure”—your form goes to trash, you start doing weird stuff just to get the bar up. Then there’s “absolute failure,” where the weight might as well be glued down because it’s not budging, no matter how many angry faces you make. Both are part of the whole set failure vs non-failure discussion.
What Does the 2025 Study Say?
So, here’s what they cooked up: a 10-week, all-in, full-body workout plan. We’re talking three or four sets per exercise, somewhere between 4 and 10 reps. Not rocket science, but solid. And of course, it sets the stage for testing set failure vs non-failure in a real program.
Now, Group A had this funky thing going on—they started each workout further from failure and crept closer as they went. Like, first set? Four reps left in the tank. Next set? Three. Then two. Last set? Basically, right on the edge—just one rep left before total wipeout. That’s a pretty clear look at set failure vs non-failure in practice.
Group B? No games, just beast mode every single set. They always finished each set with just one rep to spare. No easing in, just straight-up intensity from the jump. A textbook example of the “always push hard” side of set failure vs non-failure.
Basically, the whole idea was to see if living on the edge of failure every set actually pumps up your muscles more than, you know, pacing yourself a bit. Science, but with more sweat—and a perfect showdown of set failure vs non-failure.

What Were the Results?
Yeah, so, honestly? The research didn’t really find much difference between the groups. Didn’t matter if people pushed themselves to almost total failure (1 rep left in the tank) or played it a bit safer and kept like, 4 reps in the chamber—they still built muscle about the same. That’s the big takeaway when comparing set failure vs non-failure.
Only tiny thing? The folks grinding out those last reps (1 RIR) saw their triceps blow up a bit more. But, the scientists basically shrugged and said, “Eh, could just be random individual stuff.” So, even that doesn’t tip the scales much in the set failure vs non-failure debate.
Personally, that tracks for me, when I finally chilled out and stopped going full maniac on every single set, my recovery shot way up, and my gains didn’t magically disappear. Who knew you didn’t need to die on every rep, right? That’s exactly why the whole set failure vs non-failure conversation actually matters for normal lifters.
Practical Take-Home
Look, the 2025 Springer study pretty much spells it out: you don’t need to absolutely wreck yourself on every set to get jacked. Seriously, you can leave a few reps in the tank—like, 3 or 4 reps in reserve—and still make killer gains. Chasing failure every single set? Not really some magic shortcut. It just leaves you more wiped out for no extra payoff. Work smarter, not harder, you know? And that’s the core lesson in set failure vs non-failure.
Bonus Point for Natural Lifters
If you’re not juiced up, your body’s got limits, plain and simple. Pushing yourself to failure every single time? Yeah, that’s a fast track to burning out instead of getting jacked. Your muscles start breaking down faster than you can build them—total backfire. That’s why the whole set failure vs non-failure question matters so much.
Leaving a couple of reps in the tank (that RIR thing) is like playing it smart instead of just playing tough. You still get the gains, but your body doesn’t wave the white flag from exhaustion. Work hard, sure, but don’t be a hero every set or you’ll be spinning your wheels. That’s the smarter side of set failure vs non-failure.
Why This Study Matters Beyond the Gym
Honestly, it’s not all about going beast mode and chasing muscle. Figuring out when to chill and not slam every set to failure? That’s how you actually stick with training for the long haul. You dodge burnout, actually pay attention when your body’s waving the “hey, I’m cooked” flag, and—surprise—you’re way more likely to keep showing up week after week. Consistency beats heroics, every damn time. That’s the real win in set failure vs non-failure.
Conclusion
Look, that 2025 study basically blows up the myth that you’ve gotta grind every set to failure to see your biceps grow. Turns out, you can totally stop a couple reps short—leave a little gas in the tank—and still pack on muscle and strength. Plus, your body isn’t wrecked for days. Wild, right? That’s the big takeaway in set failure vs non-failure.
If you’re lifting without “assistance” (wink), smashing yourself every session is just plain dumb. Training smarter, not just harder, is the move. Using RIR (that’s “reps in reserve,” by the way) isn’t some nerdy hack—it’s actually the ticket to getting bigger over time without feeling like you got steamrolled every week. Trust me, your joints and your sanity will thank you. And yeah, that’s why set failure vs non-failure matters more than people think.
FAQs
Should beginners train to failure?
Not really. People new to lifting need to learn proper form, stay consistent, and understand RIR. Pushing to failure too soon can cause injuries or burnout. That’s why beginners especially need to grasp set failure vs non-failure early on.
Is training to failure useless?
No. It can help with smaller isolation exercises like curls, but it works better when you use it instead of depending on it. This is a perfect example of set failure vs non-failure in practice.
How can I estimate RIR?
After every set, ask yourself this: “Can I add 1, 2, or maybe 3 more good reps?” That count becomes your RIR. You get better at it with practice, which is key for mastering set failure vs non-failure.
