🔍 Introduction
For years, it was believed that short rest periods between sets (30 to 60 seconds) were better for hypertrophy because they created greater muscle pump and fatigue (metabolic stress).
However, modern research has shown that these temporary responses are not responsible for muscle growth.
In reality, rest serves a much simpler and more practical purpose: allowing you to perform at your best in the next set.
Resting less than needed reduces the quality of your repetitions, your ability to maintain intensity, and, as a result, the total training stimulus you can achieve.
💡 What Science Says
The myth of short rest periods emerged because studies from the 1980s and 1990s observed that training protocols with higher metabolic stress (high repetitions, short rests, compound lifts) caused temporary increases in anabolic hormones.
But more recent research has proven that muscle growth does not depend on these hormonal spikes, but rather on the total amount of effective work performed with sufficient load and proper technique.
The more you rest (within reason), the more force you can produce in each set — and therefore, the greater the effective training volume you accumulate.
⚙️ How to Determine Your Rest Periods
The best rest period is the one that allows you to perform at your best without unnecessarily extending your session.
🔹 Heavy Compound Exercises
(Squat, deadlift, bench press, pull-ups, barbell rows, overhead press)
Recommended rest: 2:00 to 4:00 minutes between sets.
Reason: These exercises require significant neuromuscular effort and central nervous system recovery.
Tip: If your goal is maximal strength, don’t rush. The quality of your next set depends on full recovery.
🔹 Accessory or Small Muscle Group Exercises
(Biceps curls, triceps extensions, lateral raises, leg extensions, etc.)
Recommended rest: 1:30 to 2:00 minutes between sets.
Reason: They demand less global effort and allow for faster recovery.
🔁 Balancing Time and Performance
The goal is not to minimize rest, but to optimize it:
Rest enough to maintain performance.
Avoid excessively long breaks that cool down your body or prolong your session unnecessarily.
Adjust the duration according to your goal (more rest for strength, less for density or muscular endurance).
General Rule:
If your performance in the next set drops by more than 10–15%, you rested too little.
🔍 How Gravl Manages Rest Periods
Gravl incorporates these principles into each routine based on your training goal and workout type:
In strength programs, rest times between sets are longer (around 3 minutes).
In hypertrophy programs, rest times are moderate (1:30 – 2:00 minutes).
💬 Conclusion
Rest periods are not a minor detail — they’re a key variable for maintaining training quality.
The most common mistake is resting too little, which reduces true intensity and limits progress.
In Gravl, rest intervals are designed to maximize performance without wasting time.
Train with intention, rest with purpose, and let recovery work in your favor.
