Bigger Leaner Stronger PDF Summary Audio Book Michael Matthews


Bigger Leaner Stronger: The Simple Science of Building the Ultimate Male Body focuses on the best tips for building muscle and losing fat. Michael Matthews gives you a blueprint for how you can start eating and exercising your way towards a bigger, leaner, and stronger body. He claims this book should offer the advice required to gain 10 to 15 pounds of lean mass in only 8-12 weeks.

About Michael Matthews

Michael Matthews is a bestselling fitness author of Bigger Leaner Stronger, Thinner Leaner Stronger, and The Shredded Chef. He is also the founder of Legion Athletics. His simple and science-based approach to building muscle, losing fat, and getting healthy has helped him sell over a million books. His work has been featured in many popular outlets, including Esquire, Men’s Health, Elle, Women’s Health, Muscle & Strength, and more, as well as on FOX and ABC.

“‘Newbie gains’ are very real and boil down to the simple fact that your muscles respond exceptionally well to just about any type of training for the first three to six months. Simply put, you can make all kinds of mistakes in the beginning and still produce better-than-average progress. This doesn’t last long, though. Once the “magic” runs out, it’s gone forever, and what worked for the first few months won’t necessarily continue to work.”

– Michael Matthews


Progressive Tension Overload

“What drives muscle growth, then? The answer is known as progressive tension overload, which means progressively increasing tension levels in the muscle fibers over time. That is, lifting progressively heavier and heavier weights. You see, muscles must be given a powerful reason to grow, and nothing is more convincing than subjecting them to more and more mechanical stress and tension.”

– Michael Matthews

Michael Matthews believes that progressive tension overload is fundamental to growing and sustaining a highly muscular body. He defines progressive tension overload as incrementally increasing the heaviness of the weights that you are lifting. As your muscles grow, using the same heaviness of weight will lower the tension placed on your muscle fibers. However, to continue to grow your muscles, you must continue to increase this tension level by increasing the heaviness of your weights. Michael Matthews highlights you can listen to all the other advice in this book and still fail to build muscle if you do not progressively overload. Therefore, always add another rep or a little bit of weight compared to your last workout. 

Matthews explains that the concept of progressive overload is not solely a modern one. Instead, the ancient Greek hero Milo was said to have carried a cow on his back daily from childhood. However, over the years, the cow grew in size. Crucially, as the cow grew, so did Milo’s physique. Milo’s strength grew in proportion to the increase in weight he had to carry.

Finally, progressive overload can be a highly effective motivator. If you notice progress in the weight you can lift, you notice progress even if progress is not yet visible on your body. Track what you lift, so you beat that weight every workout. Achieving incremental goals activates the reward center of the brain, which releases dopamine. Over time, these regular dopamine releases can actually change neural pathways to signal the expectation of reward when it comes time to work out. This rewiring of the brain can improve workout stamina and motivation to hit the gym even on a hard day.

“Muscles only grow if they are forced to.”

– Michael Matthews

Use Free Weights and Compound Weightlifting 

Resistance machines are commonly used because they seem less intimidating than holding dumbbells, bars, and plates. However, Michael Matthews argues these machines are less effective for building muscle. By using your free weights, you are better able to utilize compound exercises. These exercises recruit multiple muscle groups rather than isolating a single muscle group. Although isolation exercises are valuable, they are only valuable for strengthening certain muscle groups.

One of the greatest benefits of compound weightlifting is that it is associated with a greater release of anabolic hormones than resistance machines. These hormones, like testosterone and growth hormone, are essential for improving muscle growth. 

Feed Your Muscles With Food and Rest

“Lift hard and heavy, get sufficient rest, and feed your body correctly.”

– Michael Matthews

Matthews believes the majority of weight training programs do not offer enough rest. Weight training, if done correctly, should create micro-tears in your muscle fiber. Crucially, muscle growth occurs when these fibers are repaired. However, if you do not provide your body with sufficient rest, it will not effectively repair these micro-tears. The author suggests it can take between two and seven days to let your body fully repair. However, this does not mean you should leave seven days between workouts. Instead, rest specific muscle groups before training them again.

As well as resting your body, you also need to feed your body properly. Therefore, you need to ensure you plan out your diet correctly (which we will get to later on in this summary).

Cardio Can Also Help You Build Muscle

One of the biggest myths within the fitness world is the belief that all cardio leads to muscle loss. Matthews agrees that excessive cardio can cause muscle loss. However, he also highlights that moderate amounts of cardio performed appropriately can aid muscle growth. For example, cardio exercise can facilitate muscle-fiber repair by increasing body flow to the relevant muscle areas. This blood flow transports the minerals that are essential for muscle repair and carries away waste products. The result is shorter recovery times and improved muscle growth. However, since cardio exercises mainly employ the legs, like running and cycling, these benefits mainly serve the legs rather than upper body muscles.

The Bigger Leaner Stronger Weight Training Method

Michael Matthews summarizes his advice by offering a specific formula to adhere to while weight training. 

1–2 | 4–6 | 9–12 | 2–3 | 45–60 | 5–7 | 8–10

  1. Train 1–2 Muscle Groups Per Day.
  2. Do Sets of 4–6 Reps for Nearly All Exercises.
  3. Do 9–12 Heavy Sets Per Muscle Group.
  4. Rest 2–3 Minutes in Between Sets.
  5. Train for 45–60 Minutes.
  6. Train Each Muscle Group Once Every 5–7 Days.
  7. Take a Week off Training Every 8–10 Weeks.

Plus, Matthews also recommends four specific exercise types:

  1. The bench press
  2. The military press
  3. The squat
  4. The deadlift 


Eat Less Energy than You Burn

Let’s say your base level of calories burned in a day is 2,000, and you decide to take in only 1,500 calories per day. If you stick to this, you will lose weight. This is a scientific fact. Therefore, track the energy you ingest in your diet and make sure it is lower than the energy you have spent. If you keep to this approach, you will lose weight even if you are eating terrible food that adds up to 1500 calories. However, macronutrients also play a crucial role in muscle growth.

Use Macronutrients Properly to Optimize Body Composition 

“A high-protein diet is absolutely vital for building muscle and preserving it when you’re dieting for fat loss. A low-protein diet is absolutely good for nothing. End of story.”

– Michael Matthews

You will lose weight no matter your diet composition as long as you are in a calorie deficit. However, the composition of your diet is still essential for optimizing your body composition. Mathews explains you are at risk of becoming skinny fat if you are not paying attention to what you are eating. If you are eating too little protein while cutting, you will lose more muscle than you gain. Additionally, if you eat too few carbs, your training will suffer. Specifically, your muscle recovery will be impaired, and you will lack energy. Finally, if you eat too little fat, you will experience a significant drop in testosterone levels and other undesirable effects. 

Aim to balance out your macronutrient levels. In doing so, you will maintain your energy levels, gain muscle, and maintain hormone levels and cell functions. Plus, if you want to gain muscles, you will need to feed your body more energy than it is burning. These energy stores are crucial for repairing your damaged muscles and packing on lean muscle.


Proteins will be a hugely important part of your diet. However, it is essential you choose the right foods to obtain your protein from. Whole food protein is a protein that comes from natural food sources. Hence, the best forms of whole food protein are chicken, turkey, lean red meat, fish, eggs, and milk.


Sugar is a class of sweet-tasting carbohydrates that comes from various plants, fruits, grains, and other sources. The danger of sugar is that it’s fast-absorbing and leaves you hungry soon after. Glucose is a sugar that occurs widely in nature and is an important energy source in organisms. Glucose is a component of many carbohydrates. Eat carbs in the medium-high range of the glycemic index (70–90 is a good rule of thumb) about 30 minutes before you train and within 30 minutes of finishing your workout.

Saturated Fats

“Keep your intake of saturated fats relatively low (less than 10% of your total daily calories). Saturated fat is found in foods like meat, dairy products, eggs, coconut oil, bacon fat, and lard. If a fat is solid at room temperature, it’s a saturated fat.”

– Michael Matthews

It is difficult to build any muscle while in a fat loss calorie deficit. The goal while on a fat loss diet is simply to preserve muscle. Get most of your fats from unsaturated sources like olive oil, nuts, peanut oil, avocados, flaxseed oil, safflower oil, sesame oil, or cottonseed oil. 


Most people eat too much sodium (salt), which causes bloating. You should have a 1:2 ratio of sodium to potassium. Therefore, 4,600 mg of potassium a day.

Block Eat on a Schedule

Another myth associated with training is that you have to eat six smaller meals rather than three larger meals a day. This myth states that eating more frequently increases your metabolism. However, Matthews points out that a small meal causes a small and short metabolic spike. Comparatively, the usual three meals cause a long metabolic spike. When you take these spikes over the course of the day, you cannot identify a clear difference. Therefore, Matthews argues you should focus far more on planning a diet you enjoy and benefit from rather than caring about when you eat. 

“It’s important to eat within an hour or so of finishing your weight training, and to eat a substantial amount of carbs, and a moderate amount of protein. For most guys, this means about 80 grams of medium–to–high–GI carbs, and 30-40 grams of protein.”

– Michael Matthews

Matthews believes the only times you should schedule your meals are pre- and post-workout. Specifically, you should consume protein before working out to obtain a spike in amino acid levels and protein synthesis rates. Hence, you will be more efficient at building muscle during the workout. On top of this, you should also eat carbohydrates before a workout to provide the fuel boost required to power your muscles. Then, having completed a workout, Matthews recommends eating more protein to stimulate protein synthesis. Plus, eat some more carbohydrates to inhibit protein breakdown.
