How Long Does It Take to Build Muscle?

Embarking on the journey to sculpt your physique is a formidable challenge. But the burning question remains: just how long does it take to build muscle? Unraveling this enigma requires us to navigate a labyrinth of variables, from your training regimen and nutritional choices to the intricate science of macronutrients. After all, even with the best adjustable dumbbells at your disposal, you’ll hit a dead-end if you neglect protein intake and the principle of progressive overload. And let’s not forget the age-old influencers: age, gender, and genetics, each playing their unique role in shaping your bodybuilding odyssey.

For insights into the intricate world of muscle development, we sought guidance from none other than the eminent exercise physiologist, Bianca Grover. Let’s embark on this quest to discover the secrets of muscle building.

The Elusive Timeframe

Grover, the expert, reminds us that there’s no universal timetable for crafting your dream physique. “It all hinges on your training regimen, adherence to nutrition, and ample rest,” she wisely remarks. However, for a rough estimate, she points to a 2018 study from the European Journal of Applied Physiology, which delves into the interplay of skeletal muscle damage and muscle protein synthesis.

According to this research, glimpses of muscle growth may start to emerge after about ten sessions. But it’s not until you’ve accumulated around 18 sessions that substantial muscle hypertrophy becomes evident. The journey to substantial muscle growth is evidently a marathon, not a sprint.

Early Gains and Surprising Discoveries

Now, let’s dive into the fascinating world of muscle evolution. The study postulates that the initial muscle size increase during the early stages of resistance training (approximately four or fewer sessions) can be attributed to “muscle damage-induced swelling.” It’s only after ten sessions that a “modest magnitude of muscle hypertrophy” takes root, and it’s not until you’ve powered through roughly 18 workouts that you’ll witness the true transformation of muscle hypertrophy.

However, here’s where it gets intriguing. A 2017 study in the European Journal of Applied Physiology suggests that “significant increases in lean mass” could manifest after a mere seven workout sessions spread across four weeks. In this study, 13 untrained men undertook the challenge of dumbbell curls and shoulder presses twice a week for a month. Their dedication and 500 milliliters of whole milk intake were key to these surprising results.

The Vulnerability of Muscle Atrophy

But the journey to muscle growth isn’t just about progress; it’s also about protecting your gains. The last thing you want is to see your hard-earned muscles waste away due to atrophy. The factors contributing to muscle loss can include a lack of exercise, insufficient nutrient intake, or a combination of both. Thankfully, muscle atrophy doesn’t occur overnight.

Grover reassures us that the rate of atrophy varies, depending on your current physical condition. The more physically fit you are, the longer it will take to atrophy, and the slower the process will be. Nevertheless, after a week of minimal activity, you might begin to notice the first signs of muscle atrophy. A 2014 study published in the Acta Physiologica journal highlights that even short periods of muscle disuse can result in substantial loss of skeletal muscle mass and strength. It’s a sobering reminder to stay active and maintain your hard-earned gains.

The Science of Muscle Growth Unveiled

To unlock the secrets of muscle growth, it’s crucial to understand the underlying science. Resistance training creates tiny tears in your muscles as they move through a range of motions under a heavy load. These micro-tears are then repaired and enhanced, with amino acids (proteins) serving as the essential building blocks.

In essence, muscle growth hinges on a combination of muscular effort (typically achieved through resistance or weight training) and an adequate protein intake. Grover shares invaluable insights on how to maximize your muscle-building potential.

Targeted Training

“If you aspire to grow specific muscles or muscle groups, a process known as hypertrophy, you must engage in exercises tailored to your goals,” Grover advises. Avoid guesswork and research your exercises thoroughly. For instance, the leg press can be adjusted to target different muscle groups based on the positioning of your feet. A small adjustment can have a significant impact on your muscle development journey.

Load Management

Growing muscles necessitates subjecting them to the right level of load. In simpler terms, if the weight you’re lifting or the number of repetitions you’re completing doesn’t challenge your muscles sufficiently, growth will remain elusive. Grover recommends that when exercising for hypertrophy, you should increase the weight while reducing the number of repetitions. This equates to working with 75% of your one-rep max, allowing you to perform eight to ten reps at a time. This load, combined with an eight to 12 rep range, is generally considered optimal for muscle growth.

The Role of Nutrition

Nutrition is a cornerstone of muscle development and recovery. Grover underscores the significance of factors such as protein source, protein quantity, carbohydrate intake, supplements, and timing. Muscle hypertrophy occurs when muscle protein synthesis outpaces muscle protein breakdown, resulting in a positive net protein balance over time.

The American College of Sports Medicine recommends increased protein intake for those engaged in regular physical activity, ranging from 1.2 to 1.7 grams of protein per kilogram of body weight per day, or 0.5 to 0.8 grams per pound of body weight. However, some studies suggest that these figures might be even higher. Proper nutrition is essential in harnessing the full potential of your muscles.

In conclusion, the journey to building muscle is a complex, multifaceted process. The timeframe varies from person to person, but by understanding the science behind muscle growth and following expert advice, you can embark on a successful and rewarding journey to achieving your dream physique.
