The ideal rest between resistance workouts is usually 48–72 hours for the same muscle group, ensuring optimal recovery, muscle growth, and injury prevention. Getting your rest intervals right is crucial—too little rest can lead to overtraining and injury, while too much rest may slow down your progress. In this guide, you’ll learn exactly how long to rest between resistance workouts, how to adjust based on your goals, and what the latest research and experts recommend.
Why Does Rest Between Resistance Workouts Matter?
Rest is not just a break—it’s when your body actually repairs, rebuilds, and grows muscle. Training too frequently without enough recovery can lead to:
- Plateaued progress or even muscle loss
- Increased risk of injuries and overuse
- Fatigue, low motivation, or burnout
- Weaker performance in future workouts
According to the American College of Sports Medicine (ACSM), proper rest is essential for both beginners and advanced lifters to see consistent results and avoid negative health outcomes (ACSM Position Stand, 2022).
How Long Should You Rest Between Sets?
The amount of rest you take between sets in a workout depends on your training goal:
- Muscle Growth (Hypertrophy): 30–90 seconds
- Strength/Power: 2–5 minutes
- Muscular Endurance: 20–60 seconds
- Beginners: 60–120 seconds
| Training Goal | Rest Between Sets | Benefit |
|---|---|---|
| Hypertrophy | 30–90 sec | Increases metabolic stress, growth |
| Strength/Power | 2–5 min | Maximizes force, energy recovery |
| Endurance | 20–60 sec | Improves stamina |
| Beginners | 1–2 min | Builds technique, safe progression |

How Much Rest Between Resistance Workouts for Each Muscle Group?
General rule:
Allow 48–72 hours of recovery before working the same muscle group again.
For example, if you train chest on Monday, wait until at least Wednesday or Thursday before hitting chest hard again. This aligns with updated guidelines from organizations like the ACSM and recent expert advice (Women’s Health Mag, June 2024).
Why 48–72 Hours?
- Muscle Protein Synthesis (MPS): Peaks within 24–48 hours post-exercise for most people, then declines (MDPI Journal, 2024).
- Recovery Time: Intense resistance training causes micro-tears in muscle fibers that need at least 2 days to fully recover and grow stronger.
- Reduced Injury Risk: Chronic soreness or pain means you need more time before training that muscle again.
Split Routines: Smart Scheduling
To maximize frequency and results, many people use split routines such as:
- Upper/Lower Split: Upper body one day, lower body the next
- Push/Pull/Legs Split: Push (chest, triceps, shoulders), Pull (back, biceps), Legs—each muscle group gets 48+ hours rest
- Full-Body Workouts: 2–3 times per week, never on consecutive days
Recent Research & Expert Recommendations
- A 2024 study in Sports found that 2–3 sessions per week per muscle group (with at least 48 hours rest between sessions) yields the best results for both strength and hypertrophy (MDPI Journal, April 2024).
- NSCA Guidelines: Recommend at least 1 day (preferably 2) between heavy sessions targeting the same muscles.
- Top trainers suggest listening to your body—if you feel lingering soreness, err on the side of caution and rest another day.
Common Questions About Rest Between Resistance Workouts
What if I still feel sore after 48 hours?
Mild soreness is normal, but if you have severe DOMS (Delayed Onset Muscle Soreness), rest longer and use light activity (walking, stretching) for recovery.
Can I train other muscles while resting one group?
Yes! Use split routines so one muscle group rests while you train another.
Does age affect recovery time?
Older adults may need extra rest—up to 72–96 hours—due to slower muscle recovery (Cleveland Clinic, 2024).
