Can rest-pause training fuel muscle growth? Here’s what the science shows

When you’re staying dedicated and putting so much effort into your strength training, you want to reap the rewards of your hard work. Seeing results over time as your muscles swell encourages you to keep going and maximize your athletic potential. Lifters and fitness buffs are swearing by rest-pause training to accelerate muscle growth. It turns out rest-pause training has been around for a long time. Here are the many benefits and what the science shows.

What is rest-pause training?

Rest-pause training is a bodybuilding method or weight training technique where you alternate between mini sets and brief rest periods. People approach rest-pause training in slightly different ways. You could perform a set and stop one rep short of failure, rest for 20-40 seconds, and then power through more reps. The intensity remains high throughout your workout session because you’re only resting just enough to fuel you to perform more reps using the same weight. Arnold Schwarzenegger and other robust bodybuilders have reportedly used this technique.

Pushing your muscles beyond your typical fatigue limits creates more muscle fiber activation and tension that drives muscle growth. For example, you could choose a weight you can perform 10 reps with. Now, perform eight to 10 reps with that weight, rest for about 20-25 seconds, and then push through another 10 reps or as many as you can after your short rest period. Keep in mind that most trainers advise that rest-pause training isn’t necessarily something you should do all the time, and it might not be suitable for everyone. Doing it too often could lead to overtraining, injury, or burnout. Make sure you give your muscles plenty of time to recover in between sessions.

What are the benefits?

Because you’re not resting much in between sets, you’ll maximize your time in the gym and reap the benefits of shorter training sessions. 

Here are some of the many reasons to try rest-pause training:

  • Increase muscle strength and hypertrophy.
  • Allow for localized muscle recovery.
  • Prompt the release of muscle-building hormones.
  • Get stronger faster by optimizing the rep range, weight, and rest period.
  • Master your technique.
  • Increase your volume and weight over time as your muscles grow.

Can rest-pause training help you build more muscle?

Rest-pause training can definitely help you build more muscle because you’re pushing yourself to perform a set of repetitions to near failure, which fuels muscle growth, strength, and definition. You’ll stick with the same weight and power through rather than taking a longer rest period and then switching to a lighter weight. Rest-pause ramps up metabolic stress, which stimulates the release of key hormones and accelerates muscle growth.

Interesting research

An interesting study published in The Journal of Strength and Conditioning Research involved one group of lifters who trained using a single rest-pause set and another group who trained using three normal sets. After six weeks of training, the lifters who used the rest-pause technique gained 11% muscle thickness in the thighs compared to a 1% increase for the ‘normal set’ group. In another example, researchers found that rest-pause sets led to greater muscular hypertrophy and strength compared to traditional resistance training.

Should you take an active recovery day or a rest day? What’s the difference?
What exercises should you try on an active recovery day?

Rest days are crucial to give your muscles time to rest and recover, especially after doing strength training or an intense workout. I remember my physical therapist always reminding me, “Take your rest days.” You’ve probably heard fitness enthusiasts discuss active recovery days, too. Just like exercise, both are important for your overall wellness and to help you enhance performance and prevent burnout. Let’s look at the difference and how you know when to take a rest day and when to take an active recovery day.
What are rest days?

During a rest day, you abstain from engaging in intense physical activities and allow your body to repair, which can lower your risk of injuries and burnout. A total rest day is a full day where you aren’t working out or being active. Try to make sufficient time to rest your muscles and avoid moderate or vigorous exercise.

Here’s why fitness buffs recommend the Cooper test to check aerobic fitness

Over the years, people have invented all sorts of methods and ways to test aerobic fitness, from seeing who can perform the most push-ups to a treadmill test with a medical professional who provides data on your blood pressure, heart rate, and more. One of the increasingly popular methods fitness buffs recommend is the Cooper test. This short test measures the distance you can cover in a specific time to assess your cardiovascular endurance.
What is cardiovascular endurance?

Cardiovascular endurance is your body’s ability to continue physical activity for prolonged periods without getting fatigued. Your cardiovascular endurance is a measure of the ability of your heart, blood vessels, and lungs to deliver oxygen to your muscles while you’re exercising. You can improve it by engaging in regular aerobic exercise like running, dancing, or cycling.

Train like a pro: Jack Nunn’s tips for using rowing to boost your fitness
The rowing machine is a low-impact cardiovascular workout that engages multiple muscle groups

Rowing on the gym machine or the glossy water is an excellent low-impact cardiovascular workout that engages and strengthens multiple muscle groups in your arms, legs, core, and back. Ergometers or rowing machines simulate the resistance and the movement of rowing on water, and they remain one of the most popular workout machines at almost every gym you go to for good reason. 

As well as providing benefits like torching calories and enhancing strength, flexibility, and endurance, I also love the feeling of stretching and working my shoulders and back. The next time you try rowing on the water, you’ll notice a boost in your rowing abilities. Plus, it’s an interesting change from the treadmill, elliptical, or exercise bike. Research shows that rowing five days a week for six weeks reduces total body fat percentage, fat mass, and cholesterol and increases back strength and trunk flexion.
