Want to gain 20 pounds of lean muscle mass and shred fat? To get results, you need to optimize. Optimize your training, diet, and lifestyle to focus on achieving your goal.
A goal that needs daily commitment and dedication, especially if you’re an ectomorph. Consequently, this post will teach you the best way to build muscle and lose fat with a bodybuilding 5 day split workout plan and a lean bulk meal plan to enjoy serious muscle growth. Let’s get started.
You must follow the right workout and diet plan to gain 20 pounds of muscle.
Want to transform your physique from skinny to muscular? I’ve got you. I’ve summarized everything I know about muscle growth regarding your training, diet, and lifestyle adjustments. Here it is.
For muscle growth, your muscles need to be trained properly. Subsequently, this is done through lifting weights, providing resistance for your muscles to work against to stimulate the three mechanisms of muscle hypertrophy – the process by which your muscles increase in size.
These mechanisms are:
- Mechanical tension refers to the amount of time your muscles are under tension in an exercise and the amount of force they need to produce to complete the movement. Consequently, your muscles aren’t aware of the size of weights used, only how much tension is being created against resistance.
- Metabolic stress is when there is a buildup of blood and oxygen deprivation (hypoxia) in the muscle, making it look ‘pumped.’ Consequently, this is achieved by working at a high rep range (15-20+ reps) to pump blood into the muscle making your cardiovascular system work harder, creating metabolic stress.
- Muscle damage is achieved by implementing progressive overload. This is typically increasing the weight in increments as you get stronger and include decreasing rest time, altering the tempo, doing more reps, or longer workouts. Consequently, this makes sure that your muscles are still getting damaged, causing micro-tears in each session to begin the cycle of tear, repair, grow.
Both heavy and lighter loads target these three mechanisms. To generate the maximum amount of force during an exercise, you don’t necessarily need to lift as heavy as possible.
In fact, force generation is maximized when you’re lifting heavy enough to provide some resistance, and the exercise is highly controlled and performed slowly (increasing time under tension). Consequently, this recruits the highest amount of motor units and muscle fibers – maximizing mechanical tension and muscle damage.
So what does it look like to consistently hit all three mechanisms during your training?
- Lifting heavy enough (to activate muscle fibers)
- Using a variety of rep and set ranges (for metabolic stress)
- Increasing the weight over time (for muscle damage)
- Performing exercises slowly (for mechanical tension) is how muscle gain occurs.
When it comes to gaining 20 pounds of muscle, what you eat is essential. Subsequently, you don’t need to eat a 2,000 calorie surplus to gain muscle. Also, it would be best if you ate enough. This is known as a lean bulk.
If you are in a slight surplus (lean bulking), it optimizes muscle building as there are circulating nutrients for maximal muscle protein synthesis. Subsequently, if you are in a caloric deficit, it is hard to build muscle as your body is in a catabolic state – breaking down tissue rather than anabolic – a state of building tissue.
According to a study published in 2004 by Sports Medicine, the optimal macronutrient breakdown should be 55 to 60 percent carbs, 30 percent protein, and 15 to 20 percent fat. Let’s explore that.
The most important macronutrient to gain 20 pounds of muscle and a staple in any bodybuilder meal plan is protein. Consequently, amino acids are the building blocks of muscle repair and synthesis.
A recent systematic review and meta-analysis published by the British Journal of Sports Medicine assessed the optimal protein intake for muscle gain in 49 studies. This is arguably the most reputable source of analysis, based on the eligibility criteria for each study needing to be a randomized controlled trial lasting for more than six weeks, the gold standard of research.
Subsequently, the researchers found that protein intake was positively correlated with muscle size and strength in every study, but there was a cut-off point. Also, researchers found that a low protein intake did stall muscle hypertrophy in some cases, but we’re talking 0.3 grams per pound.
The upper limit of the benefits of protein capped at 0.7 grams per pound of body weight. Finally, this led the researchers to conclude that 0.8 grams per pound – including a double 95 percent confidence level – was the maximum upper limit of healthy individuals’ protein requirements. The confidence level added two standard deviations to ensure to be ‘safe’ that it’s the upper limit for everyone.
Carbs are also a staple in any bulking meal plan but are best consumed around your workout to avoid excess fat gain during your bulk.
According to a study published in 2004 by Sports Medicine, the optimal macronutrient breakdown should be 55 to 60 percent carbs, 30 percent protein, and 15 to 20 percent fat.
Carbohydrates are stored in the muscles as glycogen, the preferred fuel source during exercise activity. Consequently, numerous studies have shown that glycogen positively affects anabolism and performance, particularly with individuals partaking with a high training frequency.
But too many refined carbohydrates can negatively alter your hormones and fat oxidation, which is not recommended. So go for complex carbs, as included in the lean bulk meal plan.
Fat is less discussed in terms of its connection to training performance or muscle gain. Subsequently, some believe that it slows down the absorption of protein and carbs. However, this isn’t well-established in the literature.
In reality, healthy fats are important for hormonal regulation and satiety. Consequently, eating a small amount at each mealtime will help keep you full between meals and help to counter blood sugar spikes from your carbohydrate intake.
Muscle growth actually occurs when you’re asleep. If you’re not sleeping properly, you are unknowingly activating specific pathways that activate muscle degradation. Studies show sleep deprivation causes a spike in cortisol (a stress hormone) and a reduction of testosterone and insulin-like growth factor (IGF-1), two hormones integral to muscle and strength building.
The reduction of these hormones puts us in a catabolic state, meaning we break down muscle, no matter how heavy you’re lifting. So make sure you get high-quality sleep, ideally 8 hours per night.
To build muscle fast, you can follow a diet that builds muscle and lose fat at the same time.
We aim to gain 20 pounds of muscle and cut fat simultaneously. Subsequently, it might be more difficult, but it’s possible, and there is a solid amount of evidence to support it.
A 12-week study put a group of participants in a caloric deficit, high protein, and resistance training schedule. Consequently, the group lost, on average, 9.3 pounds of fat and gained 8.8 pounds of muscle mass.
Another similarly laid out study saw the participants lose fat mass and increase muscle mass, again, consuming a high protein diet.
A study by the Journal of the International Society of Sports Nutrition studied a group of elite gymnasts put on a hypocaloric ketogenic diet for 30 days whilst also continuing professional physical training. Also, participants lost, on average, 2.6 percent body fat and gained 0.9 pounds of muscle mass. Subsequently, these elite athletes were training more than four hours per day, only consuming 22 grams of carbs, and were still able to lose fat and gain muscle mass.
As you can see, total body recomposition is possible, helping you get from skinny to muscular and achieve your dream physique. So now you understand the science, let’s get to the bodybuilding meal and workout plan.
