Introduction

In the world of high-performance fitness, a single question has echoed through weight rooms for decades: is it better to crush a muscle group once a week until it’s spent, or to hit it multiple times with more precision? For years, the "bro split"—training one body part per day, once per week—was the gold standard. But as exercise science has evolved, we’ve learned that what worked for the golden-era bodybuilders might not be the most efficient path for the modern athlete or the weekend warrior looking for sustainable results.

At BUBS Naturals, we are driven by the legacy of Glen “BUB” Doherty—a Navy SEAL, adventurer, and elite athlete who understood that peak performance is the result of both hard work and smart strategy. We believe in a life of adventure, wellness, and purpose, which is why we focus on clean, functional, science-backed supplements that support your body’s natural ability to recover and grow. Whether you’re scaling a mountain or hitting a personal best in the squat rack, understanding the frequency of your training is vital to your longevity and success.

The purpose of this article is to bridge the gap between old-school grit and modern science. By the end of this post, you will understand the physiological mechanisms behind muscle growth, the optimal number of times to train a muscle group per week, and how to structure a routine that fits your specific lifestyle. We’ll explore the nuances of training volume, the importance of recovery, and how specific supplements can support your journey.

We’re going to dive deep into the research, including landmark meta-analyses that have shifted the fitness industry's perspective on frequency. We’ll also look at practical applications, from full-body splits to upper/lower routines, and discuss how to manage fatigue so you can stay in the game for the long haul. Our mission is to help you feel great and do good, and that starts with having the right information to fuel your fire.

The core message is simple: consistency and smart frequency are the engines of progress. By optimizing how often you stimulate your muscles and how effectively you support your recovery, you can maximize your gains without burning out. Let’s explore the science of how many times to workout a muscle group per week and how you can apply these principles to your own pursuit of excellence.

The Science of Training Frequency and Hypertrophy

To understand how many times to workout a muscle group per week, we first have to look at what happens inside the muscle fibers when we lift weights. Muscle hypertrophy—the increase in muscle size—is primarily driven by mechanical tension, metabolic stress, and muscle damage. When you perform a resistance exercise, you create microscopic tears in the muscle fibers and trigger a process called Muscle Protein Synthesis (MPS).

MPS is the biological process where your body repairs and builds new muscle protein. In most individuals, MPS remains elevated for approximately 24 to 48 hours after a workout before returning to baseline. This "window of opportunity" is the scientific foundation for training frequency. If you only train a muscle group once a week, you are only stimulating MPS for a fraction of that week. By increasing the frequency, you essentially "re-spike" MPS more often, keeping your body in a more consistent state of repair and growth.

A landmark meta-analysis published in Sports Medicine by Brad Schoenfeld and colleagues examined the effects of training frequency on muscle growth. The researchers found that when total weekly volume (the total number of sets and reps) was equated, training a muscle group twice a week resulted in significantly more growth than training it once a week. The evidence suggests that for the average person looking to maximize results, hitting each major muscle group at least twice every seven days is the sweet spot.

However, frequency doesn’t exist in a vacuum. It is intrinsically tied to volume and intensity. If you decide to train your chest three times a week instead of once, you cannot simply triple your daily volume. You must distribute your weekly sets across those three sessions. This approach often leads to higher-quality sets because you are less fatigued during each individual workout. To support this increased demand on your body, staying on top of your recovery is non-negotiable. Many of our athletes find that incorporating Collagen Peptides into their daily routine helps support the connective tissues and joints that are put under stress during frequent training sessions.

Finding Your Frequency Based on Training Age

The answer to "how many times to workout a muscle group per week" often depends on where you are in your fitness journey. We like to categorize this by training age: how long you have been consistently following a structured program.

The Beginner Phase

If you have less than a year of consistent training under your belt, your body is incredibly responsive to any new stimulus—a phenomenon often called "newbie gains." For beginners, a lower frequency can be highly effective. Research shows that even 1 to 5 sets per muscle group per week can yield significant results. A full-body routine performed two or three times a week is often the best starting point. This allows you to practice the foundational movements—like squats, deadlifts, and presses—frequently enough to improve your technique (neurological adaptation) without overwhelming your recovery capacity.

The Intermediate Phase

Once you have 1 to 4 years of experience, the easy gains start to slow down. At this stage, you need to increase both volume and frequency to continue seeing progress. This is where most people benefit from training each muscle group 2 to 3 times per week. An Upper/Lower split or a Push/Pull/Legs (PPL) routine becomes very effective here. By spreading your volume across more days, you can maintain a higher intensity in each set. This is also a critical time to look at your "No BS" approach to supplementation. Using Creatine Monohydrate can support the strength and power needed to push through these more demanding intermediate phases.

The Advanced Athlete

Advanced lifters (those with 4+ years of experience) require a more nuanced approach. To eke out additional growth, you may need to experiment with even higher frequencies or specialized "specialization cycles." This might mean hitting a lagging muscle group 3 or 4 times a week while keeping other muscles at a maintenance frequency (once or twice a week). For the advanced athlete, recovery is the bottleneck. When you are training at this level, every detail matters—from your sleep to your hydration. We recommend our Hydrate or Die - Lemon to ensure your electrolyte balance is optimized for performance and muscle function during these high-frequency blocks.

Structuring the Ideal Workout Split

Choosing a split is about matching the science of frequency with the reality of your schedule. Here are the three most reliable ways to ensure you hit each muscle group the right number of times per week.

The Full-Body Split

This is a classic approach used by everyone from old-school lifters to modern athletes. You train your entire body in a single session, usually three times a week (e.g., Monday, Wednesday, Friday).

• Pros: High frequency for every muscle group; if you miss a day, you haven't missed a "body part week."
• Cons: Workouts can be long and exhausting; it’s difficult to include a high volume of isolation work for specific muscles.

The Upper/Lower Split

This split divides your body into two halves. You might train Upper on Monday, Lower on Tuesday, rest Wednesday, then repeat Upper on Thursday and Lower on Friday.

• Pros: You hit every muscle group twice a week; provides a good balance between frequency and recovery time.
• Cons: Four days a week is a commitment; the "Upper" days can become quite crowded with exercises for chest, back, shoulders, and arms.

The Push/Pull/Legs (PPL) Split

PPL organizes exercises by movement pattern. "Push" days focus on chest, shoulders, and triceps. "Pull" days focus on back and biceps. "Legs" are, well, legs. To hit a frequency of twice a week, you would need to train six days a week (Push, Pull, Legs, Push, Pull, Legs, Rest).

• Pros: Allows for a high volume of work per muscle group; very clear organization.
• Cons: Requires a high time commitment (6 days a week); can be difficult for those with high-stress jobs or busy families to sustain.

To keep your energy levels steady throughout these various splits, many in the BUBS community start their day with a coffee boosted by our MCT Oil Creamer. The medium-chain triglycerides provide sustained mental clarity and energy, which is essential when you're navigating a demanding six-day PPL split or a heavy full-body session.

The Role of Volume: Sets and Repetitions

While frequency tells us how often to train, volume tells us how much. Volume is generally defined as the number of "hard sets" you perform for a muscle group per week. A hard set is one that is taken close to muscular failure (usually within 1-3 reps of the point where you could not do another rep with good form).

Research generally points to a "U-shaped" curve for volume. Too little, and you don't provide enough stimulus for growth. Too much, and you exceed your body's ability to recover, leading to overtraining and potential injury. For most intermediate lifters, 10 to 20 hard sets per muscle group per week is the optimal range for hypertrophy.

How you distribute those sets depends on your frequency. If you are aiming for 12 sets of chest work per week:

• 1x per week frequency: You do all 12 sets in one workout. By set 8, your chest is likely exhausted, and the quality of the final 4 sets may suffer.
• 2x per week frequency: You do 6 sets on Monday and 6 sets on Thursday. You are fresher for all 12 sets, likely allowing you to lift more weight or perform better reps.
• 3x per week frequency: You do 4 sets on Monday, Wednesday, and Friday. This allows for maximum intensity in every single set.

It’s also important to vary your rep ranges. While the 6-12 rep range is the traditional "sweet spot" for hypertrophy, you can build muscle in lower ranges (1-5) and higher ranges (15-20+) as long as the effort is high. Lower reps focus more on strength and neurological adaptations, while higher reps focus on metabolic stress and endurance. A well-rounded program will often incorporate a mix of these throughout the week.

Recovery: The Silent Partner in Growth

You don't grow in the gym; you grow while you sleep, eat, and recover. This is where many people fail when they increase their training frequency. If you are training a muscle group more often, you must be more diligent about your recovery protocols.

Nutrition and Protein

To repair the damage done during training, your body needs adequate protein. A general rule of thumb is 0.7 to 1 gram of protein per pound of body weight. Beyond just protein, your body needs the building blocks for connective tissue. Our Collagen Peptides Collection offers a clean, single-ingredient way to support your joints, skin, and hair. Because our collagen is NSF for Sport certified, you can trust that you are putting only the highest quality, rigorously tested ingredients into your body.

Sleep and Stress Management

Sleep is the ultimate performance enhancer. During deep sleep, your body releases growth hormone and performs the bulk of its tissue repair. Aim for 7-9 hours of quality sleep per night. Additionally, high levels of chronic stress produce cortisol, which can be catabolic (muscle-breaking). Finding time for adventure, fresh air, and "unplugging"—values we hold dear at BUBS—is just as important as your time under the bar.

Supplements for the Long Game

Sometimes, small habits make the biggest difference in overall wellness. For example, maintaining gut health and managing inflammation can indirectly support your training. Our Apple Cider Vinegar Gummies are an easy way to support digestion and metabolic health, while our Vitamin C provides essential antioxidant support to help your body manage the oxidative stress of frequent exercise. Explore the science-backed ingredients in our primary pick for joint health—Collagen Peptides—and see how it can support your wellness journey.

Nuances of Different Muscle Groups

Not all muscles are created equal. Some muscle groups are larger, more complex, and take longer to recover, while others are smaller and can handle a higher frequency.

Large Muscle Groups (Quads, Back, Glutes)

These muscles involve multiple joints and heavy loads. A heavy session of squats or deadlifts creates significant central nervous system (CNS) fatigue. For these groups, a frequency of 2 times per week is usually ideal. Training them 3 or more times per week requires very careful management of intensity to avoid burnout.

Small Muscle Groups (Side Delts, Biceps, Calves, Forearms)

These muscles recover much faster. They are also smaller and don't place as much tax on the CNS. Many lifters find they can train their side delts or calves 3 to 5 times per week with great success. If you are following a PPL split, you might add a few sets of lateral raises or calf raises on days that aren't specifically "dedicated" to those muscles to increase their weekly frequency.

The Core and Abs

Your core is active in almost every compound movement you do. While some people train abs every day, they are still muscles that need recovery. Training them directly 2 to 3 times per week is typically sufficient for most people, provided they are doing heavy compound lifts.

A Day in the Life of a High-Frequency Athlete

To bring this all together, let’s look at how a BUBS athlete might structure a typical day when following a high-frequency training plan (like an Upper/Lower split).

6:00 AM: Wake up and hydrate immediately with a glass of water. Brew a fresh cup of coffee and stir in a scoop of Butter MCT Oil Creamer. This provides the healthy fats needed for morning focus without a heavy meal sitting in the stomach.

7:30 AM: Morning Training Session (Upper Body). The workout includes bench press, rows, overhead press, and pull-ups. During the session, they sip on Hydrate or Die - Mixed Berry to maintain peak power output and prevent cramping.

9:00 AM: Post-workout recovery. A smoothie containing fruit, oats, and a serving of Collagen Peptides. This starts the repair process for the joints and connective tissues right away. They also take two Apple Cider Vinegar Gummies to support digestive health before their first large meal.

1:00 PM: A balanced lunch with lean protein, complex carbs, and plenty of greens. This is also when they might take their Vitamin C for antioxidant support.

7:00 PM: A light evening walk or some mobility work. Active recovery is a great way to manage the soreness that comes with training muscle groups twice a week.

10:00 PM: Lights out. Total focus on the 8 hours of sleep that will allow them to hit the "Lower Body" session tomorrow with full intensity.

This routine isn't about being perfect; it's about being consistent. At BUBS, we prioritize simplicity. One scoop of the right supplement, one well-planned workout, and one commitment to your health. Shop the Collagen Peptides Collection and feel the BUBS difference in your own recovery cycle.

Avoiding the Pitfalls of High Frequency

While the science supports training muscle groups multiple times per week, there are several traps that people fall into.

The "All Out" Mentality

If you train your legs three times a week and take every single set to absolute failure (the point where you drop the weight), you will likely experience overtraining within a few weeks. High frequency requires a more calculated approach to intensity. You should leave 1 or 2 reps "in the tank" on most sets, saving absolute failure for the final set of an exercise or for specific testing weeks.

Neglecting Variety

Repeating the exact same workout three times a week can lead to overuse injuries. Instead, vary the exercises. If Monday is "Heavy Flat Bench Press," Thursday could be "Incline Dumbbell Press." This hits the muscle from different angles and reduces the repetitive stress on specific joints.

Ignoring Pain

There is a difference between "good" muscle soreness (DOMS) and "bad" joint pain. If your elbows are screaming every time you do a tricep extension, increasing your frequency is the last thing you should do. Take a step back, evaluate your form, and ensure you are supporting your body's structural integrity. This is precisely why we are so passionate about our Collagen Peptides—it's about building a body that is as resilient as it is strong.

Poor Nutrition

You cannot out-train a bad diet, and you certainly cannot recover from high-frequency training without adequate calories. Ensure you are in a slight caloric surplus or at least maintenance if your goal is growth. Use the 10% Rule—our pledge to donate 10% of all profits to veteran-focused charities—as an inspiration. Just as we give back to our community, you must "give back" to your body by fueling it properly.

Why Quality Always Beats Quantity

Throughout this discussion on how many times to workout a muscle group per week, one theme remains constant: the quality of your movement and your recovery. You could go to the gym seven days a week, but if your form is poor and your nutrition is lacking, you won't see the results you desire.

At BUBS Naturals, we take a "no-BS" approach to everything we do. We don't believe in fillers, shortcuts, or miracle cures. We believe in the power of simple, effective ingredients that are rigorously tested to ensure they help you perform at your best. This philosophy applies to your training as well. It is better to have two high-quality sessions per muscle group than four mediocre ones.

When you train with intention, you honor your body and the opportunities you have. This spirit of excellence is what Glen Doherty lived by every day. Whether he was on a mission or on the ski slopes, he gave it his all. By choosing the right training frequency and supporting it with clean supplements like our Creatine Monohydrate and Collagen Peptides, you are setting yourself up for a life of sustained adventure and wellness.

Conclusion

Determining how many times to workout a muscle group per week is a critical step in optimizing your fitness journey. The scientific consensus is clear: for the vast majority of people, training each major muscle group at least twice a week is superior to the traditional once-a-week "bro split." This frequency allows for more frequent stimulation of muscle protein synthesis, better fatigue management, and higher-quality training volume.

We have explored how your training age influences this frequency, with beginners starting at 2-3 full-body sessions and advanced lifters potentially moving toward more complex splits. We’ve discussed the essential role of volume, the importance of varying your exercises, and why small muscle groups can handle more frequent attention. Most importantly, we’ve highlighted that training frequency is only one half of the equation; recovery is the other.

Supporting your body with clean, functional nutrition is the foundation of this recovery. Whether it’s the joint and connective tissue support from our Collagen Peptides, the performance-boosting power of Creatine Monohydrate, or the essential hydration provided by Hydrate or Die, BUBS Naturals is here to provide the "no-BS" tools you need.

As you move forward, we encourage you to listen to your body. Experiment with these frequencies, track your progress, and adjust as needed. Remember that every purchase you make at BUBS Naturals helps us give back to the veteran community, continuing a legacy of service and adventure.

FAQ

Is it okay to workout the same muscle group every day?

Generally, training the same muscle group every day is not recommended for most people, as muscles need time to repair and grow. While some very small muscle groups like calves or forearms might handle higher frequencies, most major muscle groups require at least 48 hours of rest between intense sessions. If you do choose a daily frequency, the volume per session must be extremely low to avoid overtraining and injury.

What happens if I only train a muscle group once a week?

You can still build muscle training a group once a week, but it is likely not the most efficient method. Because Muscle Protein Synthesis (MPS) typically returns to baseline within 48 hours of a workout, a once-a-week frequency leaves several days where the muscle is not in an active state of growth. Training twice a week ensures that MPS is elevated more consistently throughout the seven-day period.

How do I know if I am training too frequently?

Signs of overtraining or excessive frequency include persistent joint pain, a decrease in strength or performance, chronic fatigue, irritability, and poor sleep quality. If you find that you are no longer making progress or that you are constantly "banging up" your joints, it may be time to reduce your frequency or incorporate more recovery-focused habits, such as using Collagen Peptides and ensuring you are getting enough sleep.

Should I change my frequency if my goal is weight loss instead of muscle growth?

If you are in a caloric deficit for weight loss, your body's recovery capacity is slightly reduced. In this case, maintaining a frequency of 2 times per week is still ideal to help preserve muscle mass while losing fat. However, you might need to slightly reduce the total number of sets (volume) per workout to ensure you don't overwhelm your system. Staying hydrated with Hydrate or Die is especially important during weight loss phases to maintain performance levels.
