<p>I haven’t touched a barbell much since January. I’ve been in a leaning out/hypertrophy/mobility-focused season of my training (<a href="https://www.artofmanliness.com/health-fitness/fitness/seasonal-training/">highly recommend having seasons to your training!</a>). I’ve been working exclusively with <a href="https://www.artofmanliness.com/health-fitness/fitness/dumbbell-workouts-for-men/">dumbbells</a> and my <a href="https://www.artofmanliness.com/health-fitness/fitness/full-body-cable-machine-functional-trainer-workouts/">cable machine</a>. I’m chasing <a href="https://www.artofmanliness.com/health-fitness/fitness/the-pump/">the pump</a>. I’m loving it.</p>
<p>My strength coach <a href="https://store.barbell-logic.com/art-of-manliness/">Matt Reynolds</a> continues to create my programming, and one of the things he’s incorporated into my hypertrophy workouts is myo-reps. I’d never done ‘em before, but after a few months of doing them, I’m loving them. They’re a time-saver but highly effective. I can knock out a complete upper-body workout in about 30 minutes, I get a solid pump, and I’m putting on muscle and starting to look jacked.</p>
<p>If you’re short on time but still want to build muscle, myo-reps might be worth trying. They’ll at least shake up what might feel like a boring, rote workout rut.</p>
<p>Let me walk you through what they are and how to program them.</p>
<h3 id="h.9sa7uo7mf9yp">What Is a Myo-Rep?</h3>
<p>Myo-reps were developed in the mid-2000s by Norwegian strength coach <a href="https://www.borgefagerli.com/">Børge Fagerli.</a> They’re a rest-pause technique, which means you’re stringing together what would normally be several separate sets into one extended set with very short rest breaks scattered between that extended set.</p>
<p>Here’s how it works:</p>
<p>Pick a weight at 60–80% of your one-rep max; something you could lift for 10-15 reps. Do an “activation set” of 10-12 reps, stopping one or two reps shy of failure (a Rate of Perceived Exertion of 8 or 9). Then rest for about 10-20 seconds. Fagerli recommends counting out 3-5 deep breaths. I just count “one Mississippi, two Mississippi, three Mississippi” until I get to twelve Mississippi.</p>
<p>Then you do a “mini-set” of 4 to 5 reps with the same weight.</p>
<p>Rest another 10-20 seconds.</p>
<p>Another mini-set.</p>
<p>Rest another 10-20 seconds.</p>
<p>Keep repeating these mini-sets and short breaks until you can’t hit 4 reps in a mini-set. If you’ve got the weight set at the right amount, you’ll usually be able to complete 4-5 of these mini-sets.</p>
<p>So one activation set plus 3-5 mini-sets. You’ve essentially done what would be 4-5 traditional sets compressed into a few minutes.</p>
<h3 id="h.ynjvpuqcphy8">The Theory Behind Myo-Reps</h3>
<p>Muscle growth is driven by two main mechanisms: <a href="https://www.artofmanliness.com/health-fitness/fitness/podcast-933-the-science-of-swole-how-to-grow-your-muscles/">mechanical tension</a> and metabolic stress.</p>
<p>Mechanical tension is the primary driver. It’s the force your muscle fibers generate when they contract against resistance. When a fiber is loaded hard enough, specialized mechanosensors in the cell trigger the signaling pathway that tells your body to build new muscle.</p>
<p>Tension isn’t about how heavy the weight feels to you. It’s about how hard each individual fiber is working. A moderate weight can produce high tension in a specific fiber if that fiber is doing all the work.</p>
<p>That’s where the “effective reps” model comes in. In a traditional set of 12, the first 6-8 reps don’t contribute as much to growth. You’re mostly warming up the high-threshold fast-twitch fibers (the ones most responsible for hypertrophy) by exhausting the smaller slow-twitch fibers first. The last 4-6 reps, when fatigue forces your body to recruit those big fast-twitch fibers, are where the magic happens.</p>
<p>Myo-reps let you skip the warm-up phase after that first activation set. Once you’ve fatigued the slow-twitch fibers, the fast-twitch fibers have to handle every subsequent rep. They’re working at maximum capacity even though the weight feels relatively light, producing the kind of high-tension contractions that drive growth. Nearly every rep in your mini-sets is an effective rep. That’s the idea, at least.</p>
<p>The short rest periods also create metabolic stress, which can (in theory) sensitize muscles to anabolic signaling. It’s why myo-reps feel so pumpy. You’re creating a hypoxic environment similar to what <a href="https://biolayne.com/articles/training/beginners-guide-blood-flow-restriction-training/">blood flow restriction training</a> does, but without the bands.</p>
<h3 id="h.5sge704o85oy">Why Do Myo-Reps?</h3>
<p>The biggest reason to do myo-reps is that they save time. You’re knocking out the equivalent of a few traditional sets in a few minutes. It’s been nice getting through my workouts in about half an hour.</p>
<p>But there are other benefits, too. Because you’re working with 60-80% of your one-rep max instead of grinding heavy weight, myo-reps are easier on your joints. The limited rest time forces you to train close to failure. Most guys leave way too much in the tank on accessory work. It’s hard to do that when you’re cranking out mini-sets with 12 seconds of rest. Myo-reps break the monotony of the traditional three sets of ten. And you get a great pump, which is nice.</p>
<p>Basically, myo-reps will get you results that are close to what you get with straight sets with long rests in between, in less time. They’re not completely optimal for strength-building, however, as the short rests make it harder to move more weight and achieve progressive overload. That’s why they work best as a tool for accessory work and as something to use every now and then to mix up your programming, rather than as a wholesale replacement for a traditional set/rest scheme.</p>
<h3 id="h.u78kkzibcz1o">Which Exercises to Use Myo-Reps On</h3>
<p>Myo-reps aren’t for every lift. Because you’re pushing close to failure with very short rests, you need exercises where fatigue-induced form breakdown won’t get you hurt.</p>
<p>So don’t use myo-reps on heavy barbell squats, presses, deadlifts, or the bench press. The stabilization demands are too high, and getting stuck under a loaded bar during your fourth mini-set is a good way to end up in the ER. Skip Olympic lifts entirely. Cleans and snatches are explosive movements that need to be done fresh. And if you do Bulgarian split squats, pass on myo-reps. Requires too much stability.</p>
<p>For myo-reps, stick with machines, cables, and dumbbell movements.</p>
<p>Great myo-rep exercises include machine chest presses, lat pulldowns, cable rows, dumbbell shoulder presses, leg presses, leg extensions, hack squats, leg curls, dumbbell lateral raises, bicep curls, and tricep pushdowns. Anything where the path of the weight is guided or the movement is simple enough that you can grind through the last reps without your form collapsing. You could also use myo-reps with bodyweight exercises like push-ups and air squats.</p>
<h3 id="h.gdi1sktj1pbz">How to Program Myo-Reps</h3>
<p>If you’re doing a traditional barbell/strength focused program, keep your heavy compound lifts as traditional straight sets. You want fresh energy and full recovery when you’re squatting or benching near your max.</p>
<p>Save myo-reps for the back half of your workout when you’re doing accessory work.</p>
<p>Here’s a simple approach: pick two to three accessory exercises per workout to do as myo-reps.</p>
<p>So on an upper body day where the bench press is your main lift, do dumbbell shoulder presses, lateral raises, and dumbbell curls as myo-reps. On lower body day where the barbell squat is your main lift, do leg extensions and leg curls as myo-reps.</p>
<p>Your activation set should feel like an RPE 8 or 9. That’s about one or two reps shy of failure. Track your reps in the mini-sets. If you’re consistently hitting 4 clusters of 5 reps, bump the weight up next session.</p>
<p>Frequency-wise, you can hit a muscle group with myo-reps 2-3 times a week. Just remember these are an intensity technique. Don’t turn every set of every lift into a myo-rep set. That’s just a recipe for burnout.</p>
<h3 id="h.p91j1b9dtxu4">Give Myo-Reps a Shot</h3>
<p>If you’re like me and trying to build muscle without spending 90 minutes in the gym every day, give myo-reps a shot. They reduce your workout time, can make your workouts feel fresh, and can help you pack on some serious muscle.</p>
