Strength and muscle-building routines typically involve sets. After performing a specific number of repetitions (“reps”), you take a brief pause before continuing. However, the ideal length of this break varies based on several factors, including your workout goals.
Powerlifters often rest for up to five minutes between squat sets, while calisthenics enthusiasts might only pause for 30 seconds before starting another round of pullups. That said, for many individuals, the exact duration of rest intervals may not be a critical factor.
The Importance of Rest Intervals
Extended rest periods between sets enhance recovery, while shorter breaks allow you to accomplish more during your gym session.
Selecting the ideal rest duration for each exercise maximizes your gym performance. However, the best rest interval depends on the type of exercise and your fitness objectives. Let’s explore the advantages and disadvantages of both long and short rest periods.
When to Opt for Longer Rest Periods
Longer rest intervals (three minutes or more) are ideal for strength training aimed at boosting both power and proficiency with heavy weights. To lift heavy effectively, you need ample practice and recovery time. After a demanding lift, your body requires several minutes to prepare for the next significant effort.
During the three to five minutes of rest between sets of exercises like barbell squats, your muscles replenish their ATP stores. Increased blood flow delivers oxygen and nutrients to muscle cells while removing waste products. A longer rest ensures you approach the next set with maximum strength.
Taking longer rest periods—within reasonable limits—ensures better recovery for your next set. Resting for just one minute may leave you fatigued when resuming, but allowing more time enables you to lift heavier weights effectively.
Drawbacks of Extended Rest Periods
The primary issue with long rest intervals is inefficient time use. Workouts become lengthier if you rest for five minutes between sets instead of one or two. Additionally, distractions like scrolling through social media can extend breaks unintentionally. Using a rest timer can help maintain focus.
Some individuals feel restless during prolonged rests and fill the time with activities like pushups or jumping jacks. However, this undermines the purpose of extended recovery. Save such supersets for accessory exercises after your main lifts, where the goal is lifting heavy.
What Defines a "Long" Rest Period?
For exercises targeting large muscle groups, such as squats or deadlifts, a five-minute rest is standard once you reach your working weights. Warmup sets, however, require less recovery time.
For strength-focused exercises involving lighter lifts or smaller muscle groups, like the overhead press, three minutes of rest is typically sufficient.
When to Opt for Shorter Rest Periods
Shorter rest intervals are often more effective for muscle growth, or hypertrophy. While strength and hypertrophy are related, they are distinct goals. If your aim is to increase muscle size or achieve a more toned physique rather than lifting maximum weights, focusing on optimal rest times for hypertrophy is key. These rest periods are generally shorter than those for pure strength training.
Fitness experts often suggest keeping rest periods under 90 seconds for hypertrophy. (The National Academy of Sports Medicine recommends 0 to 60 seconds, while the National Strength and Conditioning Association and the American Council on Exercise advise 30 to 90 seconds in their training guidelines.)
However, studies indicate that shorter rest intervals may not necessarily enhance muscle growth more than longer ones. A 2016 study revealed that three-minute rest periods resulted in greater muscle growth compared to one-minute rests. Researchers attributed this to the three-minute group lifting heavier weights, as both groups performed the same number of sets.
A more recent meta-analysis (pending full peer review and publication) also supports longer rest periods. The analysis concluded that 30 to 60 seconds is likely insufficient, recommending one to two minutes as optimal for muscle growth. Resting beyond two minutes provided no additional benefits.
Drawbacks of Short Rest Intervals
Shorter rest periods limit the amount of weight you can lift. While this is acceptable for light dumbbell workouts, it prevents practice with heavier weights. For those aiming to build both muscle size and strength, short rests skew results toward hypertrophy rather than strength gains.
Very brief rest intervals (under a minute) may hinder maximum progress, as highlighted in the studies above. Compensating with additional sets can help if you prefer the fast-paced nature of short rests. However, for most individuals, taking a full minute between sets is more effective than rushing through workouts.
What Constitutes a "Short" Rest Period?
Recent research suggests that one to two minutes is the optimal range, aligning with the higher end of the 30 to 90-second recommendations. While varying rest lengths is acceptable, setting your timer to 90 seconds is a reliable choice if you prefer a specific guideline.
Combining the Benefits of Long and Short Rest Intervals
A balanced approach incorporating both long and short rest periods is often ideal, as many training programs are structured this way. Use longer rests for major compound lifts early in your session (e.g., squats or bench presses) and shorter rests for circuits, accessory work, or isolation exercises later (e.g., curls or glute bridges).
Supersets offer an effective compromise. By alternating exercises that target different muscle groups, you can rest one set of muscles while working another. This method may not suit maximal effort lifts (like aiming for a bench press PR), but it’s excellent for hypertrophy-focused training. For instance, try pairing exercises like this:
Perform a set of pullups
Rest for 30 seconds
Complete a set of pushups
Rest for another 30 seconds
In this scenario, if the pushups take 30 seconds, you’ve effectively rested 90 seconds between your first and second sets of pullups.
Optimal Rest Periods for Specific Exercises
What if your goals include both strength and muscle growth? Or if you simply want to avoid overthinking and appear confident at the gym? Here’s a quick guide:
Pushups and Pullups: For low to moderate reps (under 12), treat them as strength exercises with three to five minutes of rest. If you’re performing high reps (20 or more), aim for one-minute rests to manage fatigue and keep your workout efficient.
Barbell Squats and Deadlifts: These compound lifts engage multiple muscle groups and are typically performed with heavy weights. Rest three to five minutes to maximize strength gains.
Bench Press, Overhead Press, Chest Press, and Shoulder Press: These exercises target smaller muscles but are still compound and strength-focused. Rest two to three minutes, extending to five for heavier sets.
Rows and Lat Pulldowns: Similar to presses, rest two to three minutes, with up to five minutes being acceptable.
Isolation Exercises: For exercises emphasizing muscle burn or pump, shorter rests of 30 seconds are ideal.
These are general recommendations, so feel free to adjust based on your needs. For improved cardiovascular conditioning, reduce rest times. If you’ve already completed a heavy bench press session, shorten rest periods for subsequent arm and chest exercises.
All Your Rest Time Questions, Answered
Let’s tackle this quickly, as rest intervals are a hot topic for gym-goers mastering their routines. But first, a reminder: don’t overcomplicate it. Resting until you feel ready to continue is often sufficient.
Is a Three-Minute Rest Between Sets Excessive?
Not at all. For heavy lifts, a minimum of three minutes is advisable. If your focus is muscle growth rather than strength, shorter rests are acceptable. Resting longer isn’t harmful—it’s just less time-efficient.
Can You Rest for an Hour Between Sets?
At that point, it’s less of a rest period and more of a separate workout session. Returning to the gym after an hour would require a full warm-up again. If more than 10 to 15 minutes pass between sets or you feel your body cooling down, consider doing light exercises like pushups to stay warmed up while waiting for equipment.
What’s the Ideal Rest Time for Gym Beginners?
As a beginner, you’re likely not lifting heavy weights yet, so your body doesn’t require extensive recovery. For instance, if you’re learning squats, your focus is on form rather than handling 300 pounds. This means shorter rest periods are often sufficient.
For this reason, newcomers may not need long rests. Two minutes between squat sets is fine if you feel prepared. However, be cautious: consistently short rests might lead to using weights that are too light. After a few weeks, incorporate longer rests (at least three minutes) for heavier lifts to gauge your recovery and performance.
What Are the Consequences of Skipping Rest Between Sets?
If you can perform multiple sets of an exercise without taking breaks, the weight you’re using is likely too light. The distinction between three sets of 10 reps and one set of 30 reps is intentional. When your workout plan specifies 3x10, you should feel sufficiently fatigued after the 10th rep to require at least a minute or two of rest before continuing.
Yes, it might feel awkward to stand idle at the squat rack, perhaps even checking your phone, while others wait. However, keep in mind that everyone needs rest between sets—or at least they should.
