When dedicated gym-goers ask “how can I build more muscle?”, the answer invariably involves protein and resistance training. You’re lifting heavy, logging your sets, tracking your weight, but are you maximising the gains from nutrition, especially from dietary protein intake and protein timing? In this article we’ll examine how protein supports hypertrophy, the role of amino acids and muscle recovery, the interplay between resistance exercise and protein synthesis, and how to practically apply this scientific knowledge.
The process of muscle growth (hypertrophy) fundamentally depends on muscle protein synthesis (MPS) exceeding muscle protein breakdown (MPB). Following resistance exercise, the balance between synthesis and breakdown is shifted towards synthesis, but only if sufficient amino acids (from dietary protein) are available. Phillips and colleagues, in a study published in 2010 showed that combining resistance exercise with dietary amino acids amplifies muscle protein synthesis beyond the effect of training by itself.1
Resistance training acts as a trigger; protein intake supplies the building blocks. Without the trigger (training), protein alone produces limited hypertrophy. Without the building blocks (protein/amino acids), training cannot fully deliver the muscle-accretion potential. A key meta-analysis found that additional protein intake produced small but significant gains in lean body mass and lower-body strength in subjects undergoing resistance training.2
In short: to maximise muscle growth, you need both effective resistance training and optimal protein intake. This sets the stage for exploring how to optimize protein and resistance training together.
Resistance exercise increases the sensitivity of muscle to amino acid availability, meaning that after a workout the muscle is more “primed” to build. For instance, the 2010 review by Burd and colleagues highlights that amino acid provision post-exercise stimulates MPS and shifts net protein balance positive.3
A more recent meta-analysis (2022) found a clear dose-response relationship between total protein intake and gains in muscle strength only when combined with resistance training.4 The effect plateaued at approximately 0.68 g per pound of body weight per day in trained subjects. Another meta-analysis reported that protein supplementation combined with resistance training significantly improved both muscle size and strength; without the resistance training component the effect was minimal.5
Not all proteins are equal. Essential amino acids (EAAs), and notably the branched-chain amino acid leucine, play a key signalling role in triggering MPS via the mTOR pathway.6
An early human study showed that ingestion of 6 g of EAAs after resistance exercise improved net muscle protein balance.7
Table 1 – Key Mechanisms at a Glance
| Mechanism | Role in Muscle Growth |
| Resistance training stimulus | Initiates increased MPS and muscle adaptation |
| Dietary protein/EAAs | Provide substrate and signalling for MPS |
| Leucine and other EAAs | Trigger anabolic signalling (via mTOR) |
| Total daily protein intake | Determines magnitude of hypertrophic response |
| Training + protein synergy | Maximises lean body mass gains and strength |
Having understood the mechanisms, let’s look at how much protein, when to take it, and how to integrate it smartly with training.
The Recommended Dietary Allowance (RDA) for protein intake is 0.8g/kg. The RDA represents the minimum amount of protein needed to meet our basic nutritional needs in terms of proteins. However, it is important to keep in mind that it does not represent an optimal protein intake, especially in our case where we are interested in body recomposition. In addition, your protein needs can vary depending on various factors (age, physical activity, body composition, health goal etc.). Nevertheless, the question is still unanswered: what our protein intake should be – to maximize muscle growth when following a resistance training routine?
As with many questions in nutrition, there is not a clear-cut answer that applies to everyone. The topic is complex and depends on many factors, including exercise intensity, gender, age, calorie intake, etc. For a deeper breakdown of intake targets by body weight, training level, and goals, read our guide on how much protein you actually need for muscle growth.
Practical takeaway:
So as a very general guideline, we recommend 1g of protein/pound of body weight. However, it is important to realize that that number will vary depending on many factors (muscle mass, height, fitness goals etc.) Therefore, you do not need to get caught up too much in it, but it serves as a baseline. You should adjust your number as you progress in your fitness journey and know your body better.
Per-meal distribution and timing
The concept of a narrow “anabolic window” immediately post-workout has been challenged. A 2013 study found that total daily protein intake was a stronger predictor of hypertrophy than precise timing.
Nevertheless, evidence shows that muscle is more receptive to protein for up to 24-48 hours post resistance exercise.
Another review emphasises that ingestion of different forms of EAAs or high-leucine formulations increases MPS via acute kinetics (plasma EAA rise correlated with FSR).8
Suggested distribution:
While whole-food protein sources (meat, poultry, fish, eggs, dairy, legumes) should form the core of intake, supplementation (e.g., whey protein) can help reach intake targets, especially around training or when whole-food intake is impractical. For a clean whey option designed to support serious training goals, see Ethica Isolate 100 Whey Isolate Protein. A review focused on whey protein found that when combined with heavy resistance training, it stimulated greater gains in MPS and cross-sectional area than training alone.
To organise your training across the week without overloading recovery, use a structured weekly training split that matches your frequency, volume, and progression goals.
Since you track progress (weight, strength, muscle mass), evaluate every week:
Q1. Do I really need to drink a protein shake immediately after training to build muscle?
Not necessarily. While post-workout protein intake is helpful, the latest evidence shows the total daily protein intake matters more than the precise timing. However, one high-quality protein meal after training is a smart practice.
Q2. Will eating too much protein harm my kidneys if I train hard?
In healthy individuals, higher protein intakes (within reason) are generally safe. But if you have underlying kidney disease, high protein intake may pose risks. Always consult a physician.
You already train regularly and track your progress, now it’s time to fine-tune your nutrition to match your ambition. Focus first on locking in your total daily protein intake (~1 gram per pound of body weight), distribute it evenly across meals, pair it with an effective resistance training programme, and ensure recovery (sleep, stress, nutrition) is solid. Use high-quality supplemental protein if whole-food intake falls short.
As you apply these evidence-based strategies, you’ll align training + nutrition in a way that maximises muscle growth and strength, not by hype, but by science.
