The Simple Science of Building the Ultimate Male Body

“Every time you buy one of the big bodybuilding magazines, you’re paying to be lied to”.

About the Author

  • Michael Matthews is a bestselling fitness author and the founder of Legion Athletics.

The Book in One Sentence

  • No matter how bad you might think your genetics are, no matter how lost you might feel after trying and abandoning many types of workouts, you absolutely, positively can have the lean, ripped body that you dream about.

The Five Big Ideas

  1. “Every time you buy one of the big bodybuilding magazines, you’re paying to be lied to”.
  2. “70–80% of how you look is a reflection of how you eat”.
  3. “If you don’t eat enough calories and get enough protein, carbs, and fats throughout the day, you simply don’t grow”.
  4. “For optimal muscle growth, you must lift in such a way that causes optimal micro-tearing and then you must feed your body what it needs to grow and give it the proper amount of rest”.
  5. “Getting ripped boils down to nothing more than manipulating a simple mathematical formula: energy consumed versus energy expended”.

Bigger Leaner Stronger Summary

According to Matthews, most personal trainers are a waste of time and money because they don’t know what they’re talking about. 

Seventy to eighty percent of how you look is a reflection of how you eat.

The 6 Biggest Muscle Building Myths & Mistakes

  1. More Sets = More Growth
  2. You Have to “Feel the Burn” to Grow
  3. Wasting Time with the Wrong Exercises
  4. Lifting Like an Idiot
  5. Lifting Like a Wussy
  6. Eating to Stay Small or Get Fat

“If you don’t eat enough calories and get enough protein, carbs, and fats throughout the day, you simply don’t grow.”

“By lifting weights, you are actually causing tiny tears (known as ‘micro-tears’) in the muscle fibers. which the body then repairs, adapting the muscles to better handle the stimulus that caused the damage. This is the process by which muscles grow (scientifically termed hypertrophy).”

“For optimal muscle growth, you must lift in such a way that causes optimal micro-tearing and then you must feed your body what it needs to grow and give it the proper amount of rest.”

“Building muscle and getting stronger requires lifting heavy weights, and doing short, intense sets of relatively low reps. This type of training causes optimal micro-tearing for strength and growth gains, and forces the body to adapt.”

“Studies have shown that, depending on the intensity of your training and your level of fitness, it takes the body 2–5 days to fully repair muscles subjected to weight training.”

“The amount of sleep that you get plays a crucial role in gaining muscle.”

“You could do the perfect workouts and give your muscles the perfect amount of rest, but if you don’t eat correctly, you won’t grow—period.”

Matthew’s rule of thumb is to lift hard, lift heavy, get sufficient rest, and feed your body correctly.

The Building Blocks of Proper Nutrition

There are seven aspects of nutrition that are of primary concern when trying to build muscle and lose fat. 

  1. Calories;
  2. Protein;
  3. Carbohydrates;
  4. Fats;
  5. Water; 
  6. Vitamins; and
  7. Minerals.

Protein, carbohydrates, and fats are known as “macronutrients” and how you structure these in your diet is vitally important to your overall results.

Vitamins and minerals, which are known as “micronutrients,” are essential for the body’s performance of many different physiological processes connected with building muscle and losing fat.

A gram of protein is 4 calories, as is a gram of carbohydrate. A gram of fat is 9 calories.

A GI rating of 55 and under is considered “low GI” and 56 to 69 is medium, and 70 and above is high on the index.

Eat This, Not That—Bigger Leaner Stronger Version

There are two main sources of protein: 

  1. Whole food protein; and
  2. Supplement protein 

Whole food protein is protein that comes from natural food sources, such as beef, chicken, fish, etc. The best forms of whole food protein are chicken, turkey, lean red meat, fish, eggs, and milk. Protein from meat is particularly helpful when you’re weightlifting.

“Meat” doesn’t only mean red meat. Fish, chicken, turkey, pork, buffalo, and so on all qualify as “meat.” Matthew’s recommends that you stick to the lean varieties of meats as eating a lot of saturated fat just isn’t necessary. That means fish, extra-lean cuts of beef (95% lean ground beef, or extra-lean cuts like top sirloin steak, and top and bottom round roast and steak), chicken, turkey, pork tenderloin, and so forth.

In order to meet your daily protein requirements, here are your choices: 

  • Whole Food Proteins Lean meats (beef, pork, chicken, and turkey)
  • Fish
  • Eggs 
  • Vegetarian sources 
  • Protein Supplements 
  • Egg Whey Casein 
  • High-quality plant-based protein supplements

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.

Matthew’s favorite pre- and post-workout carbs are bananas and rice milk, but other good choices are unprocessed foods on the high-GI list above, such as baked potato, white rice, instant oatmeal, and fruits that are above 60 on the glycemic index, such as cantaloupe, pineapple, watermelon, dates, apricots, and figs.

All other carbs you eat should be in the middle or low end of the glycemic index (60 and below is a good rule of thumb).

Below are some examples of tasty, healthy carbs that you can include in your diet:

  • Multi-grain bread
  • Multi-grain muffin
  • Whole grain sourdough bread
  • Basmati rice
  • Brown rice
  • Apple
  • Yam
  • Black beans
  • Peanuts
  • Almonds
  • Strawberries
  • Blackberries
  • Oatmeal
  • Oranges

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

“Completely avoid trans fats, which are the worst type of dietary fat. Trans fats are found in processed foods, such as cookies, cakes, fries, and donuts. Any food that contains ‘hydrogenated oil’ or ‘partially hydrogenated oil’ likely contains trans fats, so just don’t eat it.”

Get much of your fats from unsaturated sources such as olive oil, nuts, peanut oil, avocados, flaxseed oil, safflower oil, sesame oil, or cottonseed oil. If a fat is liquid at room temperature, it’s an unsaturated fat.

How to Plan Your Meals to Maximize Your Gains

“About 30 minutes before training, you want to eat about 30 grams of high-GI carbs and about 30 grams of fast-digesting protein (such as whey).”

“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.”

Matthew’s likes egg protein powder or 0% fat Greek yogurt or low–fat cottage cheese for his pre-sleep protein, but casein is another common choice.

When bulking, two or three cheat meals per week is totally fine.

Your Bigger Leaner Stronger Diet Plan

  • Bulking. When you adjust your diet to maximize muscle gains with the usual byproduct of gaining some fat along the way.
  • Cutting. When you adjust your diet and usually also add cardio to your training routine in order to maximize fat loss with the usual byproduct of minimal muscle growth.
  • Maintaining. When you adjust your diet to enable you to make slow muscle gains without the addition of any fat. 

To gain significant amounts of muscle (ten pounds or more), bulk until you’ve gained the size you want, and then cut to lose the fat.

Matthew’s recommendation is to bulk to a size that’s a little bigger than what you want and then cut.

Here’s how to determine your starting point for bulking: 

  • Eat 1 gram of protein per pound of body weight per day. 
  • Eat 2 grams of carbs per pound of body weight per day. 
  • Eat 1 gram of healthy fat per 3 pounds of body weight per day.

“Some guys find that their bodies do better with fewer carbs and more fats. If you know or suspect this about your body, you can drop your carbs by 50 grams per day and increase your fats by about 20 grams per day to replace those calories.”

“Depending on whether you’re new to weightlifting or experienced, you’re expecting to gain anywhere from 0.5 to 2 pounds per week when bulking, with a minor, gradual increase in body fat.”

“If you aren’t gaining weight or strength or your energy levels are low after a couple of weeks of bulking, you should up your calories by about 300 per day for another week or two and see if that fixes it. The easiest way to add calories is to eat about 70 more grams of carbs per day.”

Adjust your calories up by about 200 for every fifteen pounds that you gain.

“Eat at least about 30% of your daily carbs in your post-workout meal. This is about 80–100 grams for most guys, but feel free to go higher you’d like.”

“As a general rule, try to get at least 50% of your daily protein from solid food. It makes a difference.”

The Bigger Leaner Stronger Training Formula

The Bigger Leaner Stronger weight training method follows a formula that looks like this: 

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

  • Train 1-2 muscle groups per day
  • Do sets of 4-6 reps for nearly all exercises
  • Do 9-12 heavy sets per muscle group
  • Rest 2-3 minutes in between sets
  • Train for 45-60 Minutes
  • Train each muscle group once every 5-7 days
  • Take a week off training every 8-10 weeks

For the first 6–9 months of being on this program, Matthew’s recommends that you try weeks of complete rest. If you definitely don’t like how your body feels after trying a few full rest weeks, or if you come back weaker, then try the “De–load Week.”

The rep timing Matthew’s recommends is known as a “2-1-2” timing. This means the first part of the rep should take about two seconds, then there should be a pause, followed by the final portion of the rep, which should take about two seconds.

If you’re bulking, Matthew’s recommend 2-3 days of cardio per week.

There are three primary ways that cardio can help you build (and retain) more muscle. They are as follows: 

  1. It improves muscle recovery by increasing blood flow to muscles. 
  2. It improves your body’s metabolic responses to food, helping you minimize fat storage. 
  3. It keeps up your conditioning, making the transition from “bulking” to “cutting” easier on your body.

How to Improve Your Strength While Preventing Injury

“A correct warm-up introduces blood into the muscle group being trained and its supporting muscles while progressively acclimating them to heavy weight, but it does NOT fatigue the muscles.”

How to Warm Up

  • In your first warm-up set, you want to do 12 reps with about 50% of your “heavy set weight” and then you rest for 1minute. 
  • In your second set, you use the same weight as the first and do 10 reps this time at a little faster pace. Then rest for 1 minute. 
  • In your third set is 4 reps with about 70% of your heavy weight, and it should be done at a moderate pace. Then rest for 1 minute. 
  • The fourth set is the final warm-up set, and it’s very simple: 1 rep with about 90% of your heavy weight. Then rest 2–3 minutes before starting your next sets. 
  • Your fifth, sixth and seventh sets are your heavy, muscle–building sets.

The only exception to the above is the rare case of moving on to an exercise that involves muscles that would not have been warmed up, such as going from Lat Pulldowns to Deadlifts.

Your Bigger Leaner Stronger Workout Plan

The Bigger Leaner Stronger Workout Plan calls for five days of weightlifting, as much cardio as you’d like to do based on your goals and what you now know, and two days of rest from the weights, and one day of complete rest (no exercise whatsoever).

Day 1

  • Chest and Abs Flat Bench Press: Warm-up sets and then 3 working sets (4–6 reps per set) 
  • Incline Bench Press: 3 working sets (4–6 reps per set) 
  • Dip (Chest Variation, weighted if possible): 3 working sets (4–6reps per set) 
  • Cable Crunch: 3 sets (enough weight to allow 10–12 reps per set) Captain’s Chair Leg Raise (no weight, as many as you can do): 3 sets 
  • Air Bicycles (no weight, as many as you can do): 3 sets

Day 2 

  • Back and Calves Barbell Deadlift: Warm-up sets and then 3 working sets 
  • One–Arm Dumbbell Row: 3 working sets 
  • Close–Grip Lat Pulldown: 3 working sets 
  • Seated or Standing Calf Raise: 6 sets (enough weight to allow 10–12 reps per set)

Day 3

  • Shoulders Seated Barbell Military Press: Warm-up sets and then 3 working sets 
  • Side Lateral Raise: 3 working sets 
  • Bent-Over Rear Delt Raise: 3 working sets 
  • Barbell Shrugs: 3 working sets

Day 4

  • Legs Barbell Squat: Warm-up sets and then 3 working sets 
  • Leg Press: 3 working sets 
  • Romanian Deadlift: 3 working sets


  • Arms and Abs Alternating Dumbbell Curl: Warm–up sets and then 3 working sets 
  • Triceps Pushdown: Warm–up sets and then 3 working sets
  • Barbell Curl: 3 working sets Seated Triceps Press – 3 working sets
  • Cable Crunch: 3 sets 
  • Captain’s Chair Leg Raise: 3 sets Air Bicycles – 3 sets

If there’s no way for you to lift five days per week, Matthews recommends the following three-day program:

  • Day 1: Chest (warm-up and 9 working sets) & triceps (6 working sets, no warm-up needed) 
  • Day 2: Back (warm-up and 9 working sets) & biceps (6 working sets, no warm-up needed) 
  • Day 3: Legs (warm-up and 9 working sets) & shoulders (warm-up and 9 working sets)

Matthews likes to change out an exercise or two from each workout every 8–10 weeks (after his De–load Week). He’ll then do that new routine for the next 8–10 weeks, take a week off, change up the exercises, and keep the pattern going.

Matthews recommends the following exercises:


  • Chest Dumbbell Press (flat, incline) 
  • Barbell Bench Press (flat, incline) 
  • Weighted Dip
  • Back Barbell Deadlift Pull–Up (weighted if possible)

The No-BS Guide to Supplements

“Most everything you see in the world of workout supplements is utterly worthless.”

“Unless you are in the lucky position of being able to have whole food meals ready 4–6 times per day, you’re going to need to use protein supplements.”

“Whey is particularly effective when eaten after training, due to its rapid digestion and abundance of leucine.”

“The three forms of whey protein sold are whey concentrate, isolate, and hydrolysate.”

“Whey concentrate is the least processed form and cheapest to manufacture, and it contains some fat and lactose.”
