Rest-pause training is a high-intensity hypertrophy technique designed to increase muscle-building reps without dramatically increasing workout time. Instead of performing one straight set and stopping, you take very short rest periods and continue the set in mini-bursts with the same weight.
Because it extends a hard set beyond initial fatigue, rest-pause training is considered an advanced, high-intensity method. Yet when applied strategically, it can also be surprisingly time-efficient, allowing you to stimulate more muscle in fewer total sets.
In this guide, I’ll explain what rest-pause training is, how it works, what the research says, and how to use it properly so you build more muscle without compromising recovery.
Rest Pause Training: From Bodybuilding Origins To Modern Science
There aren’t that many studies about rest pause training, but when I was doing my weekly review of hypertrophy and exercise physiology science recently, I stumbled onto an interesting paper that was published in the journal, Applied Nutrition, Physiology, And Metabolism.
It confirmed that rest pause training is indeed an effective technique. But more than that, rest pause is also a versatile technique that can be used for intensity, time efficiency, and progressive overload.
Added: Evidence now confirms that rest pause might even be the most effective all the intensity techniques. But this really isn’t a new breakthrough… the method has been around for years…
Legend has it that Sergio Oliva used rest-pause training way back in 1969 when he became the only bodybuilder to ever defeat Arnold Schwarzenegger in the Mr. Olympia contest. Sergio was huge – his arms were ridiculous. They had to be to beat Arnold, right?
Over the years, this technique has become very popular among bodybuilders. Most competitive physique athletes know about rest pause, but oddly, I don’t think many average recreational lifters do.
That’s too bad because looking at the results top physique athletes have achieved using the rest pause method, it has been clear for a long time that it works. And now, the science agrees. A study in the Journal Of Applied Physiology, Nutrition, And Metabolism in 2019 and another in the Journal Of Strength And Conditioning Research in 2021 both agree: Rest pause works.
What The Newest Studies Say About Rest Pause Training
On the surface, the recent research results didn’t look that exciting because in both studies, the scientists essentially said, “rest pause training works as well as traditional training.”
In one case, it was slightly better for strength, and in another case there was 11% more growth in the thigh muscles with rest pause.
But basically the researchers concluded the muscle growth was about the same compared to regular training.
So what’s the big deal then? Why are we raving about it? Why not just do regular sets?
The reason is because what the researchers did find is that the people doing rest-pause training achieved that same muscle growth in less time.
Rest Pause Training Is Time Efficient
Training techniques that give you time efficiency while not compromising your muscle gains are the most valuable ones you can use when you are busy and short on time.
If you’ve followed me a while then you know I’m a big fan of supersets, especially antagonistic supersets. Superset training is so efficient it can cut your workout time by up to 50% with little or no compromise in muscle gains.
It’s no surprise that my superset training program – TNB TURBO – which has been around since 2018, is still my best selling weight training program of all time.
But supersets aren’t the only time-efficiency technique you can use. Rest pause training can be used in a variety of ways, and using rest pause workouts for time-efficiency is one of them.
In fact, the authors of one of the recent studies said that the results of 1 set of rest pause were similar to the results of 3 sets of traditional training.
The other huge benefit of rest pause is that it can be another method of progressive overload
Saving time isn’t the only use for rest pause. In fact, the second benefit of rest-pause is the main reason I use it myself: to guarantee that you achieve progressive overload at every workout.
Progressive overload on a well-designed training program is the key to muscle growth. It’s so important I wrote a whole book about it.
A big reason people still struggle with this is because they think progressive overload only means adding weight. But what they don’t realize is that adding reps (even at the same weight) is also a form of overload.
Make no mistake, adding weight is still the most effective way to overload. But since we can’t add weight to the bar at every workout, or even every week, we need other ways to do it, and they all have to do with increasing volume (total sets and reps performed).
Unfortunately, we can’t just keep adding more and more exercises and more and more traditional sets with 2 or 3 minute rest periods because if we do, now time efficiency goes out the window and we’re in the gym all day!
Just like supersets, rest pause is a game changer because you can get the same muscle gains in less time, and you don’t have to increase the weight you lift to get those gains.
What’s really exciting is that the rest pause technique is so simple, I can explain it to you in seconds.
How To Do Rest-Pause Training
Perform a set as usual with a weight that lets you do 8 to 12 reps and take it to within 1 or 2 reps short of failure (a hard effort).
Put the weight down and rest, but only briefly (about 15 to 20 seconds).
Since you’ve rested just long enough for partial muscle recovery (50% regeneration of ATP in 20 seconds), you can now do more reps (the number can vary, but it’s usually about 3 or 4 more, maybe 5).
Put the weight down and rest again for 10 to 20 seconds. That’s one round of rest-pause. (Some people call each round of additional reps “mini sets.”)
Repeat for about 3 to 4 rounds doing as many reps as you can each time.
That’s one rest pause set completed (the main set plus all the extra reps done in mini sets)
Now take a normal full rest period (about 2 minutes or so) before moving on to the next set or the next exercise
It’s normal for the reps to drop with each round so the reps in the rest pause rounds might look like this: 5, 4, 3, 3 or 4, 3, 3, 2, or 4, 3, 2, 1 or 4, 3, 2 or 4, 4, 3
You can see that essentially rest pause is a clever way to “sneak in” extra reps at the end of a regular set.
Lifters who are new to this technique might do only 1 round of rest-pause reps and they might only do it on one exercise.
Seasoned bodybuilders usually perform about 3 rest pause rounds and they might do rest pause sets on more than one exercise in a workout. Sometimes a lifter will keep doing more rounds until they can’t do any more – they keep going until they can barely even do 1 rep and that’s their signal to end the set.
Keep the rest / pause periods short (10 to 20 seconds) and be judicious about too much training to failure
Some coaches or athletes say you should rest 30 or 40 seconds when doing rest pause, but I don’t agree. If you rest longer than 20 seconds, it’s no longer the rest-pause technique, it’s just a regular straight set with very short rest periods. I would call that “density training” not rest pause training.
Some people also say you must take the main set to failure as well as all the mini sets. That’s an option, but training to failure causes a large amount of muscle damage, makes you accumulate a large amount of fatigue and adds to your recovery needs. It also can’t be done on every exercise without exposing yourself to injury risk.
Also, if you go to total failure on the main set, then for sure you’ll get fewer reps in the mini sets. This is why it’s usually preferable to train close to failure (a hard effort), but stop the main set with 1 or 2 reps left in the tank.
(Note: you can safely go to failure more often on isolation exercises and some machine exercises. A lot of failure training on heavy compound exercises can zap you right into the ground).
When To Use Rest-Pause
Generally you would not use rest pause on every exercise for every muscle group. It’s more often used as a specialization technique to help bring up a slow growing muscle.
You could do rest pause for every set of an exercise for one particular muscle group. But an ideal way to use rest pause is to save it for the last set of each exercise. This is what I usually do, so I don’t accumulate too much fatigue early in the workout and I don’t risk overtraining. I also do more rest pause sets or add more rounds of rest pause within a set as a way to increase volume (to overload).
If you wanted to use rest pause strictly for time efficiency, then if you were doing 3 regular sets of an exercise, you can do just 1 set of rest pause and expect similar results. This way rest pause becomes a technique for shortening your workouts.
In my opinion, the ultimate way to use rest pause is to to keep adding on volume in a time efficient way to guarantee you get progressive overload.

The longer you’ve been training and the closer you get to your genetic muscle building potential (ceiling), the less often you can increase the weights.
At this level, adding weight at every workout or even every week is impossible and should not be expected. When you’re advanced and especially when you get to the end of a training block, it often gets hard to even add another rep every workout.
But if you use rest pause, you have a secret weapon that always allows you to add reps. Just do a set and take it close to failure. Put the weight down. Pause 15 or at most 20 seconds. Pick the weight back up and do a handful more reps. Overload achieved!
Added: Granted those reps may not have been consecutive reps, but you get the reps and your total volume for the workout goes up just the same.
You can continue to achieve progression by doing more rounds of rest pause or using the technique on more sets in a workout.
Now, go try some rest-pause training for yourself, and let me know how it goes!
