Introduction

Did you know that increasing your strength levels is associated with a 31% lower risk of death? It’s a staggering statistic that reframes the conversation around fitness from aesthetics to longevity and survival. Yet, for many of us, the hurdle isn’t a lack of desire to be strong; it’s a lack of time. We often fall into the mental trap of believing that if we can’t dedicate five days a week to the iron, we might as well not go at all. At BUBS Naturals, we’re here to challenge that "all-or-nothing" mentality. Inspired by the legacy of Glen “BUB” Doherty—a Navy SEAL who lived a life of relentless adventure and purpose—we believe that doing something always trumps doing nothing. If your schedule only allows for one focused session every seven days, the science is clear: you can still make significant progress.

The purpose of this article is to dive deep into the physiological and practical reality of low-frequency training. We will explore how you can build muscle and strength with just one workout a week, the scientific studies that prove its efficacy, and the specific protocols required to make every minute in the gym count. We will also look at how clean, high-quality supplementation, like our Creatine Monohydrate, acts as the cornerstone for a minimalist training routine. By the end of this post, you’ll understand how to structure your training for maximum efficiency and how to support your body’s natural functions to ensure that one day a week translates into a lifetime of health and resilience.

We are dedicated to providing a no-BS approach to wellness. That means focusing on simple, effective ingredients and evidence-based strategies. Whether you are an aging athlete looking to maintain your edge or a busy professional trying to stay capable for the weekend’s adventures, this guide is for you. Together, we’ll explore the science of minimalist training and show you how to feel the BUBS difference in your own pursuit of excellence.

The Science of Minimalist Training

When we talk about building muscle, we are essentially discussing muscle hypertrophy—the process where muscle fibers undergo damage through intense exercise and are then repaired by the body to become thicker and stronger. Conventional wisdom suggests this requires frequent stimulation, but recent research has begun to pull back the curtain on just how little stimulus the body actually needs to initiate this change.

One of the most compelling pieces of evidence comes from a massive multi-year study involving nearly 15,000 participants. The study analyzed data from Fit20, a Dutch company specializing in 20-minute workouts performed once a week. The findings were nothing short of remarkable. Over seven years, participants saw consistent strength gains. For example, chest press strength typically increased by 30% after one year and up to 50% after seven years. Leg-press strength showed even more dramatic improvements, increasing by nearly 70% over the same period. This suggests that the body is highly adaptable, and as long as the intensity is sufficient, a single weekly session can drive progress for nearly a decade before reaching a true plateau.

Another study focused on older adults, a demographic where muscle maintenance is a matter of functional independence. Researchers at the New York Institute of Technology compared training once a week versus twice a week. They found that after nine weeks, there was no significant difference in strength gains between the two groups. Both groups improved their one-repetition maximum (1-RM) scores similarly. This is crucial because it proves that for the purpose of health, function, and longevity, the "minimum effective dose" of exercise is much lower than we’ve been led to believe.

To truly capitalize on these findings, we must focus on the quality of our input. This is where Creatine Monohydrate becomes an essential tool. Creatine supports the body’s ability to produce energy during high-intensity efforts, allowing you to push closer to that necessary point of muscular fatigue even when you only have one session to get the job done. By maximizing the intensity of your single workout, you ensure that the hypertrophy process is triggered effectively.

The Economy of Training: Why Every Set Counts

When you only have one hour a week to dedicate to your physical preparation, you are operating in a state of low "training economy." Someone who trains four days a week has a surplus of resources—time, sets, and recovery windows. If they have a "bad" workout on Tuesday, they can make it up on Thursday. When you train once a week, you don’t have that luxury. Every set must be treated with the utmost importance.

This approach requires a shift in mindset. You are no longer "going to the gym"; you are performing a mission. This reflects our commitment to the values of Glen “BUB” Doherty—excellence, preparation, and no excuses. In a low-frequency program, you cannot afford to waste time on isolation movements like wrist curls or calf raises unless the fundamental compound movements have been mastered.

The concept of the "minimum effective dose" means we are looking for the smallest amount of work that will produce the desired result. In a single-session week, this means choosing exercises that recruit the most muscle mass possible. Think of it as a biological investment: where can you get the biggest return for your time? Squats, deadlifts, presses, and rows are the blue-chip stocks of the fitness world. They stimulate the central nervous system and trigger systemic hormone responses that isolation moves simply cannot match.

Because the volume is low, the intensity must be high. This doesn’t necessarily mean lifting the heaviest weight you can find, but rather taking your sets to a point of near-failure. When you reach the point where you cannot perform another repetition with perfect form, you have signaled to your body that it is not currently strong enough to handle its environment. Your body responds to that signal by building more muscle. To support this intense cellular demand, we recommend starting your day with MCT Oil Creamer in your coffee. The medium-chain triglycerides provide a clean, sustained energy source that helps you maintain mental clarity and focus throughout your workout, ensuring you don't "clock out" mentally before the work is done.

The Pillars of the One-Day Routine

To successfully build muscle on a once-a-week schedule, your routine must be built on three non-negotiable pillars: Compound Movements, High Intensity, and Progressive Overload.

Pillar 1: Compound Movements

Compound movements involve multiple joints and muscle groups working in unison. A barbell squat, for example, engages the quadriceps, hamstrings, glutes, core, and even the upper back to stabilize the weight. In contrast, a leg extension only targets the quadriceps. When time is your limiting factor, you must choose the squat every time. By hitting the entire body in a single session, you ensure that no muscle group is left behind, even with seven days of rest between workouts.

Pillar 2: High Intensity and Muscular Fatigue

As the Dutch study on older adults highlighted, training to muscular fatigue is the key. Fatigue is the signal that tells the body to adapt. In a once-a-week program, we recommend performing at least one set of each exercise to the point where the muscle "fails." This ensures that you have recruited every available muscle fiber. Because this type of training is demanding on the joints and connective tissues, integrating Collagen Peptides into your daily routine is a smart move. Our pasture-raised collagen supports joint health and recovery, helping you stay resilient so you can bring that same intensity to the gym week after week.

Pillar 3: Progressive Overload

Building muscle is a long-term game. To keep seeing results, you must gradually increase the demand on your body. This is called progressive overload. If you lifted 100 pounds for 10 reps last week, you should aim for 105 pounds or 11 reps this week. Even small increments lead to massive gains over time. Keep a training log. When you only train once a week, it’s easy to forget exactly what you did the previous session. Tracking your progress ensures that you are always moving forward.

Nutrition and Supplementation for the Minimalist Lifter

If you are only training once a week, your nutrition and supplementation during the other six days become the foundation upon which your muscle is built. You aren't just what you eat; you are what you absorb and how you recover. At BUBS Naturals, we prioritize ingredients that support the body's natural functions without unnecessary fillers.

The most researched supplement for increasing muscle mass and strength is undoubtedly Creatine Monohydrate. It works by increasing the phosphocreatine stores in your muscles, which helps in the formation of adenosine triphosphate (ATP), the key molecule your cells use for energy. For a once-a-week trainee, creatine is a game-changer. It allows you to squeeze out those last two or three "failure" reps that are so critical for growth. Moreover, creatine has been shown to support cognitive function, keeping you sharp for the "adventure" part of our mission.

Hydration is another often-overlooked component of muscle function. Muscles are roughly 75% water, and even slight dehydration can lead to significant drops in strength and endurance. To stay at your peak, we suggest using Hydrate or Die – Lemon. It provides the essential electrolytes your muscles need to contract effectively and recover quickly. Whether you’re in the middle of a heavy set of squats or out on the trail, proper hydration ensures your body is operating at its full potential.

Finally, don't forget the importance of gut health and general wellness. Our Apple Cider Vinegar Gummies are an easy way to support digestion. A healthy gut ensures that the nutrients you consume are actually being broken down and delivered to your muscles. It’s all part of our "no-BS" approach: simple habits that lead to big results.

Sample One-Day Full-Body Routine

If you’re ready to put the "one workout a week" theory into practice, you need a plan that covers the entire body efficiently. This routine is designed to be performed once every seven days. Remember, the goal is to take each working set to the point of muscular fatigue.

1. Warm-up: 5–10 minutes of light cardio (brisk walk or rowing) followed by dynamic stretching.
2. Leg Press or Squat: 1–2 sets of 10–15 repetitions. Focus on a controlled descent and an explosive ascent.
3. Chest Press or Bench Press: 1–2 sets of 10–15 repetitions. Ensure your shoulder blades are retracted for stability.
4. Seated Row or Bent-Over Row: 1–2 sets of 10–15 repetitions. Focus on pulling with your elbows and squeezing your shoulder blades.
5. Overhead Press: 1 set of 10–15 repetitions. This targets the shoulders and triceps while demanding core stability.
6. Lat Pulldown or Pull-up: 1 set to fatigue. If you can do more than 15 pull-ups, consider adding weight.
7. Deadlift or Romanian Deadlift: 1 set of 8–12 repetitions. This is the ultimate "posterior chain" builder.
8. Plank: 1–2 rounds, holding for as long as possible with perfect form.

This entire routine can be completed in under 45 minutes. The key is to minimize rest between exercises—aim for 60 to 90 seconds—to keep the intensity high and provide a cardiovascular stimulus. Throughout this session, sipping on Hydrate or Die – Mixed Berry will keep your electrolytes balanced and your energy levels stable.

The Importance of Recovery and the 10% Rule

When you train once a week, your "recovery" period is six days long. This doesn't mean you should be sedentary. In fact, active recovery—walking, hiking, or light swimming—helps circulate blood flow to the muscles, aiding in the repair process. This is the "adventure" part of the BUBS Naturals lifestyle. We don't just train to look good in the gym; we train so we can say "yes" to the adventures that come our way.

Recovery is also about what you put into your body. While Collagen Peptides are great for your joints, we also need to ensure our immune system is supported. Our Vitamin C supplement provides antioxidant activity that supports collagen formation and overall health. When your body is healthy, it can dedicate more resources to building muscle and repairing tissue.

Beyond physical recovery, we believe in the importance of purpose. Our dedication to giving back is central to everything we do. Through our 10% Rule, we donate 10% of all profits to veteran-focused charities. This commitment honors the legacy of Glen “BUB” Doherty and provides us with a "why" that goes beyond our own fitness goals. When you choose BUBS, you aren't just buying a supplement; you are participating in a mission to support those who have served. This sense of purpose can be a powerful motivator during those final, difficult reps of your weekly workout.

Overcoming the Strength Plateau

Every lifter, regardless of frequency, will eventually hit a plateau where progress seems to stall. On a once-a-week program, this might happen sooner than it would on a three-day program, but it is not inevitable. To break through, you have to look at the variables you can control: intensity, volume, and recovery.

If you find that you haven't increased your weights in several weeks, consider "cycling" your intensity. For one week, instead of going to failure, use a slightly lighter weight and focus on perfect, slow repetitions (time under tension). This can give your central nervous system a break while still providing a stimulus. Then, the following week, return to your heavy, high-intensity sets.

Another way to break a plateau is to audit your nutrition. Are you getting enough protein? Are you staying consistent with your Creatine Monohydrate? Often, a plateau in the gym is actually a plateau in the kitchen. Ensure you are fueling your body with the simple, clean ingredients it needs to grow. If you're struggling with mid-day energy slumps that prevent you from attacking your weekly workout with vigor, try a travel pack of our Butter MCT Oil Creamer. It’s an easy way to get healthy fats into your diet, providing the sustained fuel needed to power through plateaus.

Consistency is the Ultimate Performance Enhancer

The most important factor in any training program is consistency. A "perfect" five-day-a-week plan that you quit after a month is infinitely less effective than a "good" one-day-a-week plan that you stick to for a decade. The Fit20 study proved that long-term consistency with a minimalist approach leads to significant, life-changing strength gains.

At BUBS Naturals, we want to help you make wellness a sustainable part of your life. We know that life gets messy—work gets busy, families need attention, and sometimes you just want to get outside and explore. By embracing a once-a-week training model, you remove the barriers to entry. You no longer have to feel guilty about missing the gym, because you only need to make it there once.

To maintain this consistency, make your daily routine as easy as possible. Keep a travel pack of Collagen Peptides in your bag for post-workout recovery. Have your Apple Cider Vinegar Gummies on the counter so you remember to take them every morning. These small, simple habits reinforce your identity as someone who values their health. When you see yourself as an athlete—even a minimalist one—showing up for that one workout a week becomes a non-negotiable part of who you are.

The Role of Supplements in a Minimalist Lifestyle

We’ve discussed how specific products support the physical act of building muscle, but it’s worth zooming out to see how the entire BUBS Naturals portfolio fits into a lifestyle of adventure and wellness. Our products are designed to be "mix-easy" and "no-BS," meaning they fit into your life rather than forcing you to change it.

For the minimalist lifter, supplements aren't a shortcut; they are a force multiplier. If you are only providing your body with a stimulus once a week, you want that stimulus to be as powerful as possible, and you want your body to be in the best possible state to respond to it. This is why we use NSF for Sport certified ingredients. We want you to have total confidence that what you’re putting in your body is clean, safe, and effective.

Whether it’s the joint support from Collagen Peptides, the mental clarity from MCT Oil Creamer, or the performance boost from Creatine Monohydrate, each product serves a purpose in your journey. We are here to support your active lifestyle, whatever that looks like. In the spirit of Glen “BUB” Doherty, we encourage you to live with intention, to push your limits, and to always find a way to give back.

FAQ

1. Is one workout a week enough to see visible muscle growth? Yes, it is possible to see visible muscle growth with one workout a week, provided the intensity is high enough to trigger hypertrophy. You must focus on compound exercises and take your sets to the point of muscular fatigue. While progress may be slower than a more frequent routine, science shows that consistent strength gains can be maintained for years on a minimalist schedule. Supporting your body with Creatine Monohydrate daily can also help maximize the results of that single weekly session.

2. Should I still take supplements like creatine and collagen on days I don't work out? Absolutely. Muscle repair and systemic health are 24/7 processes. Creatine Monohydrate works best when your muscle stores are consistently saturated, which requires daily intake. Similarly, Collagen Peptides provide the amino acids your joints and connective tissues need for ongoing maintenance and resilience, regardless of whether it's a training day or a rest day.

3. What if I feel very sore for several days after my one workout? When you train with high intensity only once a week, delayed onset muscle soreness (DOMS) can be more pronounced because your body isn't as "accustomed" to the frequent stimulus. This is normal. To manage this, focus on active recovery like walking and ensure you are staying hydrated with Hydrate or Die. Proper hydration and daily collagen can help support the body's natural recovery pathways and reduce the duration of soreness.

4. Can older adults benefit from a once-a-week training frequency? Yes, older adults can see significant benefits from training once a week. Research has shown that a single weekly session can be as effective as twice-weekly sessions for improving strength and functional capacity in adults aged 65–79. This is an excellent way to combat age-related muscle loss while minimizing the risk of overtraining. For older adults, focusing on joint health with Collagen Peptides is also highly recommended.
