Introduction

If you walked into a gym in the late 1990s, you would likely see rows of people performing endless crunches, hoping that the sheer volume of repetitions would eventually reveal a chiseled midsection. The "1,000 crunches a day" myth has persisted for decades, fueled by the idea that more is always better when it comes to abdominal definition. But as we have learned through advances in exercise science and a deeper understanding of human physiology, the "more is better" approach often leads to plateaus, overtraining, and frustration. The real question isn't just about how many reps you can squeeze into a session, but specifically, how many times a week should I workout my core to see actual, sustainable progress?

At BUBS Naturals, we approach fitness and wellness through the lens of our founder’s legacy. Glen “BUB” Doherty was a Navy SEAL, an adventurer, and a man who lived with purpose. His lifestyle demanded a core that wasn't just for show but was functionally strong enough to handle high-stakes environments. We believe your training should reflect that same commitment to quality and utility. Whether you are training for a marathon, prepping for a weekend of surfing, or simply want to move through your daily life without back pain, your core is the anchor of your entire physical existence.

In this guide, we are going to move past the superficial "beach body" advice and dive into the science-backed reality of core frequency. We will explore the different muscle groups that make up your trunk, how they recover compared to other muscles like your quads or chest, and why rest is just as vital as the workout itself. By the end of this article, you will understand exactly how to structure your weekly routine, which exercises provide the most "bang for your buck," and how to support your hard work with nutrition and recovery tools like our Collagen Peptides. Our goal is to provide you with a clear roadmap so you can stop guessing and start building a core that supports a life of adventure.

The Anatomy of the Core: Moving Beyond the Six-Pack

To answer the question of how many times a week you should workout your core, we first need to define what the "core" actually is. Many people use "abs" and "core" interchangeably, but this is a mistake that can lead to an imbalanced physique and an increased risk of injury. The core is a complex network of muscles that stabilizes the spine, transfers power between the upper and lower body, and protects your internal organs.

The most famous member of this group is the rectus abdominis. These are the "six-pack" muscles that run vertically down the front of the abdomen. Their primary job is spinal flexion—bringing your ribs toward your hips. While they get all the glory, they are actually just one piece of the puzzle. Flanking the rectus abdominis are the external and internal obliques. These muscles are responsible for rotation and lateral flexion (bending side-to-side). If you want that tapered, athletic look and the ability to swing a golf club or a surfboard with power, you cannot ignore the obliques.

Deeper still is the transverse abdominis (TVA). Often referred to as the body’s "natural weight belt," the TVA wraps around your midsection horizontally. It doesn't contribute much to the "look" of your abs, but it is the most important muscle for spinal stability and creating intra-abdominal pressure. Finally, we have the multifidus and erector spinae in the lower back, which work in tandem with the front-facing muscles to keep you upright.

When we consider how often to train these muscles, we have to realize they are active almost all day. Whether you are sitting at a desk or carrying groceries, your core is working to maintain your posture. Because they are primarily composed of Type I (slow-twitch) muscle fibers, they are incredibly resilient. However, to see growth and increased strength, we must still respect the rules of muscle hypertrophy. This is why we recommend supporting your structural integrity with high-quality protein and Collagen Peptides to ensure your connective tissues stay as strong as the muscles themselves.

Finding Your Ideal Frequency: The Science of Recovery

The consensus among exercise physiologists and top-tier trainers is that for most people, training the core directly two to three times per week is the "sweet spot." This frequency allows for enough volume to stimulate muscle growth while providing the 48 to 72 hours of recovery needed for the muscle fibers to repair and strengthen.

Why not every day? While it is true that your abs recover slightly faster than, say, your hamstrings, they are still skeletal muscles. Every time you perform a weighted cable crunch or a grueling set of hanging leg raises, you are creating microscopic tears in the muscle tissue. Muscle protein synthesis (MPS)—the process by which your body repairs these tears—takes time. If you hit your abs every single morning without fail, you are effectively cutting off the MPS process before it can finish. This results in what we call "junk volume," where you are working hard but seeing diminishing returns because the muscle never has the chance to actually grow.

For beginners, starting with two sessions a week is ideal. This might look like adding ten to fifteen minutes of dedicated core work at the end of your Monday and Thursday workouts. As you become more advanced and your recovery capacity improves, you can move to three or even four sessions per week. However, the intensity of these sessions must be balanced. If you are doing heavy, weighted abdominal work, you need more rest than if you are doing a few minutes of bodyweight planks and bird-dogs.

We also have to consider the "indirect" work your core receives. If your fitness routine includes heavy compound lifts like squats, deadlifts, and overhead presses, your core is already working overtime to stabilize your spine under load. On days when you are performing these heavy movements, you may not need any direct core work at all. In fact, over-fatiguing your core before a heavy squat session can actually be dangerous, as a tired core is less able to protect your lower back. To keep your energy levels high for these demanding sessions, many of our athletes rely on the MCT Oil Creamer in their morning coffee to provide sustained, clean energy without the crash.

Hypertrophy vs. Strength: Tailoring Your Core Routine

How often you train also depends on your specific goals. Are you training for the "stone slab" look of thick, visible abdominal muscles, or are you training for the functional strength required for heavy lifting and athletic performance?

If hypertrophy (muscle growth) is the goal, you should treat your abs like any other muscle group. This means using progressive overload, varied rep ranges, and resistance. Instead of doing fifty sit-ups, try doing three sets of ten to twelve reps of weighted decline sit-ups or cable crunches. Because these sessions are more taxing on the central nervous system and the muscle fibers, a frequency of two to three times per week is best. You want to focus on the "burn" and the eccentric (lowering) phase of the movement to maximize tissue breakdown and subsequent growth.

On the other hand, if your goal is pure core strength and stability, your approach will look different. Strength training often involves anti-rotational movements (like the Pallof press) and isometric holds (like planks or hollow body holds). These exercises teach your core how to resist movement, which is its primary functional role. Since these exercises focus more on neurological efficiency and endurance rather than maximal tissue damage, you can often perform them more frequently—perhaps three to five times a week—as long as the volume per session is kept moderate.

Regardless of your goal, hydration plays a massive role in muscle function and recovery. When you are sweating through a core circuit, you are losing vital minerals that facilitate muscle contractions. We recommend using Hydrate or Die - Lemon during or after your workouts to replenish electrolytes without the added sugars found in typical sports drinks. Proper hydration ensures that your core muscles can fire correctly and recover faster for your next session.

Exercise Selection: Variety is the Spice of Core Training

To build a truly impressive and functional core, you need to work in all planes of motion. The "how many times a week" question becomes easier to answer when you realize you don't have to do the same thing every time.

A well-rounded routine should include:

• Sagittal Plane Movements: These are your traditional flexion and extension exercises. Think hanging leg raises, crunches, and pikes. These primarily target the rectus abdominis.
• Frontal Plane Movements: These involve lateral (side-to-side) movement. Side planks and weighted side bends fall into this category, focusing on the obliques.
• Transverse Plane Movements: These are rotational exercises. Russian twists, woodchoppers, and medicine ball throws are excellent for developing the internal and external obliques and improving athletic power.
• Anti-Movement Exercises: These are perhaps the most underrated. Anti-rotation (Pallof press), anti-extension (dead bugs), and anti-lateral flexion (suitcase carries) are essential for spinal health and heavy lifting stability.

By rotating these types of exercises, you can effectively train your core more often without overworking any single muscle group. For example, you might focus on flexion and rotation on Monday, stability and anti-extension on Wednesday, and lateral work on Friday. This "split" approach within the core itself is a great way for advanced trainees to hit the core three times a week while still allowing specific fibers to rest.

To support the power and strength required for these movements, many of our community members supplement with Creatine Monohydrate. Creatine isn't just for your biceps; it helps provide the ATP necessary for explosive movements and high-intensity intervals, making your core sessions more effective.

The Role of Body Fat and Nutrition

We cannot discuss core training frequency without addressing the elephant in the room: visibility. You can have the strongest, most well-developed core in the world, but if it is hidden under a layer of subcutaneous body fat, no one will ever see it. This is where the old saying "abs are made in the kitchen" holds some truth. While abs are built in the gym through consistent training 2-4 times a week, they are revealed through a disciplined approach to nutrition.

To see definition, men typically need to be below 12-15% body fat, while women generally see results around 18-22%. Achieving this requires a consistent caloric deficit and a high protein intake to preserve the muscle you are working so hard to build. This is a journey that requires patience and a "no-BS" approach to what you put in your body.

We suggest starting your day with a focused nutritional ritual. Incorporating Apple Cider Vinegar Gummies into your morning routine can support digestive wellness and help you stay on track with your goals. Furthermore, using a clean protein source like our Collagen Peptides helps ensure you are getting the amino acids needed for recovery without unnecessary fillers or artificial sweeteners.

Consistency in nutrition is just as important as consistency in training. If you are diligent with your core workouts three times a week but your diet is inconsistent, you will likely find yourself in a cycle of "bulking" without ever seeing the fruits of your labor. Focus on whole foods, lean proteins, and healthy fats, and use supplements to fill the gaps, not as a replacement for a solid diet.

Lifestyle and Functional Core Integration

Training your core doesn't always have to happen within the four walls of a gym. In fact, some of the most effective core engagement happens during "stealth" training—activities that require core stability as a byproduct of the movement. This is very much in line with the BUBS Naturals philosophy of living an adventurous life.

Activities like stand-up paddleboarding, rock climbing, hiking with a weighted pack (rucking), and even intensive gardening require constant core engagement. When you are out on a trail or balancing on a board, your transverse abdominis and obliques are firing non-stop to keep you stable. If you are an active individual who spends their weekends doing these types of activities, you might find that you only need one or two "direct" core sessions in the gym to maintain your physique.

Even your daily habits at work can influence your core strength. Maintaining "active sitting"—where you engage your core to keep your spine neutral rather than slouching into your chair—can build endurance in the deep postural muscles. While this isn't a replacement for a workout, it contributes to the overall "tonnage" of work your core does throughout the week.

For those long days of adventure or work, staying on top of your antioxidant intake is crucial for managing the oxidative stress that comes with an active lifestyle. Our Vitamin C supplement is a great way to support your immune system and collagen formation, helping your body stay resilient regardless of the challenges you throw at it. Remember, a strong core is a tool that allows you to do the things you love, better and for longer.

The Importance of the BUBS 10% Rule

At BUBS Naturals, our commitment to excellence goes beyond the ingredients in our tubs. Every time you choose to support your core recovery with our Collagen Peptides, you are also supporting a much larger mission. We were founded to honor the memory of Glen "BUB" Doherty, and that legacy is baked into everything we do.

Our "10% Rule" is our promise to donate 10% of all profits to veteran-focused charities. This isn't just a corporate social responsibility checkbox for us; it is our "why." Glen lived a life of service, adventure, and extreme fitness. By supporting the organizations that help veterans transition back to civilian life and find their own new "missions," we keep Glen’s spirit alive.

When you are pushing through that final set of planks or meal prepping for the week ahead, you are part of a community that values more than just personal gains. We value the collective strength of our tribe and the drive to give back. This sense of purpose can be a powerful motivator. Knowing that your health journey contributes to the well-being of those who have served can give you that extra "oomph" to stay consistent with your routine, whether it's your two core sessions a week or your daily recovery habits.

Recovery: The Silent Partner in Progress

We have established that training 2-3 times a week is optimal, but what you do during the other four or five days is what determines if that training actually "sticks." Recovery is an active process. It’s not just about sitting on the couch; it’s about providing your body with the environment it needs to thrive.

Sleep is the ultimate performance enhancer. During deep sleep, your body releases growth hormones that are essential for repairing the tissue damage caused by your core workouts. Aim for seven to nine hours of quality sleep per night. If you find yourself struggling with soreness that prevents you from training with the necessary intensity, it may be a sign that your recovery is lagging.

Beyond sleep, we emphasize the "no-BS" approach to supplementation. Our Collagen Peptides Collection is designed to be effortlessly integrated into your life. Whether you mix it into your morning coffee or your post-workout shake, the goal is to provide your body with the building blocks it needs for joint health and muscle repair. Core training, especially movements involving spinal flexion, can put a lot of stress on the connective tissues of the back. Keeping those tissues "greased" and healthy is a non-negotiable for long-term fitness.

Furthermore, don't underestimate the power of a rest day. A day where you focus on light stretching, mobility work, or a gentle walk can improve blood flow to the muscles without adding to the recovery debt. This ensures that when your next core day rolls around, you are ready to hit it with 100% intensity.

Conclusion

Determining how many times a week you should workout your core is about finding the balance between stimulus and recovery. For the vast majority of people, two to three dedicated sessions per week—combined with the indirect work from compound lifts and an active lifestyle—is the most effective path to a strong, visible midsection. Remember that your core is a complex system that requires variety in movement, progressive overload in intensity, and a disciplined approach to nutrition to truly shine.

We’ve explored how to structure your workouts, why rest days are essential, and how to fuel your body for maximum results. But more than just sets and reps, we hope you take away the idea that your physical health is the foundation for a life of purpose and adventure. By choosing clean, functional supplements like our Collagen Peptides and following a science-backed routine, you are setting yourself up for success both in and out of the gym.

As you embark on this journey, stay consistent, stay curious, and remember the legacy of Glen "BUB" Doherty. Every scoop, every rep, and every choice to live better is a tribute to a life well-lived. Let's get to work, build that core, and make every day an adventure. If you're ready to take your recovery and performance to the next level, explore our full Collagen Peptides Collection and feel the BUBS difference for yourself.

FAQ

Is it okay to do a core workout every single day?

While you can do core exercises daily, it is generally not recommended if your goal is muscle growth or maximal strength. Like any other muscle, your core needs time to recover and repair. Training every day can lead to "junk volume" and overtraining, which may actually hinder your progress. Aiming for 2-4 high-quality sessions per week is usually more effective for long-term results.

Do I need to use weights to see my abs?

Weights are not strictly necessary to see your abs—that is primarily a function of body fat percentage—but they are very helpful for building them. Using resistance with exercises like cable crunches or weighted leg raises causes the muscle fibers to grow thicker, making them more "pop" and become visible at slightly higher body fat percentages.

Can I get a strong core just from doing squats and deadlifts?

Compound exercises like squats and deadlifts are excellent for building "functional" core strength and stability. However, they primarily engage the core isometrically (holding still). To maximize your core development and aesthetic appeal, it is beneficial to add direct core work that involves flexion, rotation, and lateral movement a few times a week.

What should I eat after a core workout to help with recovery?

After any workout, your body needs protein to repair muscle tissue and carbohydrates to replenish energy stores. A clean protein source, like BUBS Naturals Collagen Peptides, is an excellent choice as it is easy to digest and supports both muscle and joint health. Pairing it with a balanced meal of whole foods will ensure your core has the nutrients it needs to grow stronger.
