Rest Pause Sets: Why They May Not Be Giving You the Gains You Expect

By: Marc Lobliner, IFBB

Let’s get real—if you’re spending hours in the gym but not seeing the results you’re after, you’re not alone. One of the popular techniques out there, rest-pause sets, is marketed as a way to maximize muscle growth by pushing beyond failure with short breaks between reps. But recent research tells us it might not be delivering on that promise. A new study published in the Journal of Strength and Conditioning Research looks at rest-pause sets versus traditional straight sets and comes to a surprising conclusion: rest-pause sets don’t actually lead to more muscle growth than standard straight sets.

But here’s the kicker—regardless of the method you choose, what truly drives gains is intensity, progressive overload, and the willingness to push yourself in the gym consistently. Let’s dive into the science, then talk about what actually matters for making real-world gains.

The Study: Rest-Pause Sets vs. Straight Sets

In a recent study titled “Exercise Intensity and Rest Intervals: Effects on Muscle Growth and Strength,” researchers explored the impact of rest-pause sets compared to traditional straight sets. The study aimed to see if breaking up a set with brief rest intervals could stimulate greater muscle growth or strength gains than sticking to a straight set format. Participants were divided into two groups: one using straight sets (completing all reps with a consistent rest interval) and the other using rest-pause sets (taking brief, short rests between reps to extend the set beyond typical failure).

The results were surprising. Both groups experienced similar gains in muscle mass and strength over the study period, with no significant advantage for those using rest-pause sets. This goes against a common belief that rest-pause training helps you push past failure to stimulate more growth. The takeaway? The study suggests that rest-pause sets don’t provide any additional muscle-building advantage over standard straight sets.

So, Why Don’t Rest-Pause Sets Work Better?

Rest-pause training sounds like it should work—it allows you to go beyond your initial failure point by giving your muscles a few seconds to recover between reps. But here’s the thing: muscle growth is primarily driven by overall training volume, progressive overload, and the intensity of each workout. Rest-pause sets might let you squeeze out a few more reps, but they don’t necessarily add meaningful volume or stimulate the muscle in a way that’s superior to traditional sets.

Another factor to consider is the potential for fatigue management. When you use rest-pause sets repeatedly, it can be easy to hit a point of diminishing returns. If your form breaks down or you become overly fatigued, you might be compromising the quality of your reps. And quality matters. If you’re gassed out and not hitting the muscle with focused intensity, you’re wasting effort.

The Real Key to Making Gains: Intensity, Consistency, and Progressive Overload

Now, just because rest-pause sets may not be the golden ticket doesn’t mean they’re useless. It just means they aren’t necessarily superior for growth. What actually matters is how hard you’re willing to work in the gym. That’s the truth that often gets buried beneath the hype around new techniques.

Here’s the bottom line: gains come from training with intensity, pushing yourself, and progressively overloading the muscle. And this applies to everyone—whether you’re doing rest-pause sets, straight sets, supersets, or anything else.

Intensity Over Everything

Let’s break down intensity because this is where most people miss out. Walking into the gym and going through the motions won’t cut it. You need to push yourself to a level that challenges your muscles and signals them to grow. If you’re training with intensity, you’re doing the reps with purpose, focus, and controlled movement. The muscles should be working hard to complete each rep, and you should feel like you’re truly challenging your limits by the last few reps of every set.

Intensity is also about mindset. You can have the best technique in the world, but if you’re not pushing yourself mentally and physically, you won’t see the results you’re after.

Progressive Overload: The Unchanging Principle of Growth

Another concept that matters more than any specific technique is progressive overload. Your body adapts to the stress you place on it, so if you want to keep making gains, you need to continually increase the challenge. This doesn’t necessarily mean adding weight every single workout (though that’s one way to do it), but it does mean pushing yourself harder over time—whether that’s through more reps, heavier weights, better control, or increased intensity.

Progressive overload can be achieved through simple, straightforward methods like:

1. Adding weight to your lifts over time.
2. Increasing reps with the same weight to build endurance and strength.
3. Improving form and slowing down each rep for better time under tension.     

The key is to keep challenging yourself, consistently moving forward in your training. This is what separates the people who keep making gains from those who plateau.

Rest-Pause Sets: A Tool, Not a Magic Bullet

So, where do rest-pause sets fit in? They’re a tool, not a magic bullet. They can add variety to your training, help you push past mental barriers, or even be useful when you’re short on time and need a way to hit failure quickly. But remember, they’re not necessarily superior for muscle growth. Use them sparingly, as a way to add some spice to your workout or push yourself when you’re feeling stuck.

If you love doing rest-pause sets and feel they help you push harder, then go for it—just know that it’s not the end-all, be-all of muscle-building.

The Takeaway: Focus on Fundamentals

Look, if you’re trying to make gains in the gym, the best advice I can give you is to focus on the basics: train with intensity, push yourself to do better every session, and keep your diet in check. These are the fundamentals that produce real, lasting results. Rest-pause sets, supersets, dropsets, and every other technique can have their place, but they’re just tools. They won’t do the work for you.

The study is clear—rest-pause sets don’t provide any unique advantage over straight sets when it comes to muscle growth and strength. So, if you’re not seeing gains, don’t blame your technique; instead, look at the basics. Are you training hard enough? Are you eating to support your goals? Are you progressively overloading?
