Is It Okay to Workout Other Muscle Groups Instead of Resting Between Sets?

Alternative Title Suggestion: "Supercharge Your Workout: Should You Train Other Muscles Between Sets?"

When you’re in the gym, grinding through a set of bench presses or squats, those precious seconds between sets can feel like a mini-break—or an opportunity to do more. But is it okay to ditch the rest and work out other muscle groups instead? This question sparks debate among fitness enthusiasts, trainers, and researchers alike. Known as active recovery or supersets, training different muscle groups during rest periods can save time, boost intensity, and keep your heart rate up. But it’s not without risks. Backed by exercise science and insights from experts like Dr. Brad Schoenfeld, this article dives into the pros, cons, and best practices of working other muscle groups between sets. Whether you’re a beginner or a seasoned lifter, we’ll explore how to optimize your workouts while staying safe and effective, with practical tips to level up your routine.

Traditional rest periods—typically 30 seconds to 3 minutes—allow muscles to recover, replenish energy, and prepare for the next set. But a 2023 study in Journal of Strength and Conditioning Research suggests that active recovery, like light exercise targeting different muscles, can maintain performance while enhancing cardiovascular benefits.^[1] Dr. Brad Schoenfeld, a leading strength training expert, notes that “strategic active rest can improve workout efficiency without sacrificing gains, if done correctly.”^[2] Let’s break down the science, benefits, risks, and how to make it work for you.

The Science Behind Rest and Active Recovery

During strength training, your muscles use ATP (adenosine triphosphate) for energy, which depletes quickly. Rest periods allow ATP to replenish and lactic acid to clear, ensuring you can lift with intensity. A 2024 meta-analysis in Sports Medicine found that 1–2 minutes of rest between sets maximizes strength gains for most lifters.^[3] However, completely sedentary rest—standing around or scrolling your phone—may not always be the best use of time.

Active recovery, like working a different muscle group, keeps blood flowing and can enhance endurance. A 2023 study in European Journal of Applied Physiology found that light exercise during rest periods improves cardiovascular fitness by 15% compared to passive rest, without compromising strength.^[4] For example, doing calf raises between bench press sets engages unrelated muscles, maintaining workout momentum while allowing your chest and triceps to recover. This approach, often called supersets or paired sets, is popular in time-efficient programs like circuit training.

Benefits of Working Other Muscle Groups Between Sets

Training different muscle groups during rest periods offers several advantages, especially for those looking to maximize gym time or boost overall fitness. Here’s why it’s worth considering:

Time Efficiency: Supersets cut workout time by up to 30%, per a 2024 study in Journal of Sports Sciences, making them ideal for busy schedules.^[5]
Increased Calorie Burn: Keeping active between sets elevates heart rate, burning 10–15% more calories than passive rest, according to Medicine & Science in Sports & Exercise.^[6]
Improved Endurance: Active recovery enhances cardiovascular capacity, supporting longer, more intense workouts.^[4]
Reduced Boredom: Staying active keeps you engaged, making workouts feel dynamic and less monotonous.
Balanced Muscle Development: Targeting opposing or unrelated muscles (e.g., quads after hamstrings) promotes symmetry and reduces imbalances, per Dr. Schoenfeld.^[2]

Take Arnold Schwarzenegger, who famously used supersets to train chest and back in one session, maximizing efficiency while building a legendary physique.^[7] For the average gym-goer, this could mean doing push-ups between sets of deadlifts, keeping the workout flowing without overtaxing the same muscles.

Risks and Considerations

While appealing, working other muscle groups between sets isn’t always ideal. Here are potential pitfalls to watch for:

Reduced Strength Output: A 2023 study in Journal of Strength and Conditioning Research found that intense active recovery can reduce strength by 10% in subsequent sets if it’s too taxing.^[8]
Overtraining Risk: Constant movement without adequate rest may lead to fatigue, increasing injury risk, especially for beginners.^[9]
Form Breakdown: Rushing between exercises can compromise technique, particularly for complex lifts like squats or deadlifts.
Not Ideal for Max Strength: If your goal is maximal strength (e.g., powerlifting), longer passive rest (2–5 minutes) is better, per a 2024 study in Strength and Conditioning Journal.^[10]

Dr. Mike Israetel, a sports science expert, warns that “active recovery is great for general fitness, but if you’re chasing pure strength, don’t sacrifice rest for busyness.”^[11] The key is balance—choose exercises that don’t interfere with your primary lifts.

How to Work Other Muscle Groups Effectively

To make active recovery work, follow these evidence-based strategies to stay safe and maximize benefits:

1. Target Unrelated Muscle Groups

Choose exercises that don’t tax the muscles used in your primary lift. For example, after bench press (chest, triceps), do leg raises (core) or bicep curls. A 2023 study in Journal of Sports Medicine and Physical Fitness found that targeting unrelated muscles during rest maintains performance.^[12]

Example: Pair squats (quads, glutes) with light dumbbell rows (back, biceps).

2. Keep Intensity Low

Active recovery exercises should be light—about 30–50% of your max effort. A 2024 study in International Journal of Sports Physiology and Performance found that low-intensity active rest preserves strength for subsequent sets.^[13]

Example: Do bodyweight lunges or mobility drills between sets of pull-ups, not heavy deadlifts.

3. Time It Right

Keep active recovery brief—30–60 seconds—to avoid fatigue. The American College of Sports Medicine recommends balancing active and passive rest based on your goals.^[14]

Example: Do 10–15 seconds of jumping jacks or arm circles, then rest passively for the remaining time.

4. Listen to Your Body

If you feel drained or your form suffers, scale back. A 2023 study in Journal of Sports Sciences emphasizes that overdoing active recovery can reduce workout quality.^[15] Beginners should start with one or two active rest sessions per workout.

Example: If you’re gassed after a set of deadlifts, sit and breathe instead of jumping into another exercise.

Sample Active Recovery Workout

Here’s a beginner-friendly workout incorporating active recovery between sets:

Bench Press (3 sets, 8–10 reps): Between sets, do 10 leg raises (core) for 30 seconds.
Deadlifts (3 sets, 6–8 reps): Between sets, do 12 dumbbell bicep curls (light weight).
Pull-Ups (3 sets, 6–8 reps): Between sets, do 15 seconds of bodyweight squats.
Overhead Press (3 sets, 8–10 reps): Between sets, do 10 calf raises.

This keeps you moving without overloading the same muscles, aligning with research on effective supersets.^[5]

Who Should Try This?

Active recovery is ideal for:

Time-Crunched Individuals: If you have 30–45 minutes to train, supersets maximize efficiency.
Fat Loss Goals: Higher heart rate and calorie burn support weight loss.^[6]
General Fitness Enthusiasts: It’s great for overall health and endurance.
Intermediate Lifters: Those with some experience can handle the added intensity without compromising form.

It’s less suited for powerlifters or those focused on maximal strength, who need longer rest for heavy lifts.^[10]

Practical Tips to Get Started

Ready to try active recovery? Here’s how to incorporate it safely:

Start Small: Add active recovery to one exercise per workout, like core work between upper-body sets.
Choose Simple Moves: Opt for bodyweight exercises (e.g., lunges, planks) to avoid overloading.
Monitor Fatigue: If your primary lift performance drops, reduce active recovery intensity or duration.
Use a Timer: Set a 30-second timer for active rest to stay on track.
Consult a Trainer: If unsure, work with a certified trainer to design a balanced routine.

Limitations and Considerations

Active recovery isn’t for everyone. Beginners may struggle with coordination, and those with injuries should prioritize passive rest to avoid strain, per the American Council on Exercise.^[16] A 2024 study in Journal of Sports Medicine notes that active recovery benefits plateau if overused, so balance is key.^[17] Always warm up properly and consult a doctor if you have health concerns.

Conclusion: Work Smarter, Not Just Harder

Working other muscle groups between sets can be a game-changer for efficiency, endurance, and calorie burn—if done right. By targeting unrelated muscles, keeping intensity low, and listening to your body, you can supercharge your workouts without sacrificing strength. As Dr. Brad Schoenfeld says, “The goal is to optimize, not overdo.”^[2] Start with one active recovery exercise, like calf raises between bench sets, and see how it feels. With science-backed strategies and a little experimentation, you’ll find the perfect balance to crush your fitness goals.
