No matter how old you are, no matter how bad you might think your hormones or genetics are, and no matter how lost you might feel after trying and abandoning past diets and exercise routines . . .

You absolutely, positively can have the lean, strong, and healthy body you dream about, and Muscle for Life will show you how.

Here’s the deal:

Building lean muscle and burning stubborn fat isn't nearly as complicated as you've been led to believe. You don’t need to give up any of the foods you like, do a bunch of workouts you hate, or fill your cabinets with bags and bottles of exotic pills, powders, and potions.

In Muscle for Life, you’ll find a science-based blueprint for eating and exercising that anyone can follow at any age and fitness level.

Imagine watching pounds of fat melt away without ever feeling like you’re “on a diet” because you look forward to every meal, every day. Imagine adding lean muscle to all of the right places on your body by doing just a few fun and challenging workouts per week that make you strong. And imagine realizing that all of your health and fitness goals—even the ones you’ve all but given up on—are finally within your reach.

Based on time-proven principles produced by decades of hands-on experience and thousands of hours of scientific research, Muscle for Life will give you a paint-by-numbers plan for transforming your body faster than you ever thought possible, including:

  • Conquering the “mental game” of fitness. Learn to hack your habits, willpower, and mindset so your fitness regimen feels like it’s on autopilot.
  • Harnessing the science of “flexible dieting.” A whole new paradigm for eating that empowers you to forever break free of fad dieting, crash dieting, and yo-yo dieting.
  • Unlocking the power of strength training. The “secret” to optimizing your body composition, which is far more important for your health, image, and longevity than your body weight.
  • Developing effective and sustainable eating habits. Find your way to eat that supports not only your health and fitness goals but also your food and lifestyle preferences.
  • Starting a fitness regimen the right way with a comprehensive 12-week plan. Building momentum is everything—if you can get the first 12 weeks right, you'll get the first 12 months right.

Whether you’re a beginner looking for a lifestyle change, a lifelong athlete looking to reach the next level, or somewhere in between, Muscle for Life will show you how to look, feel, and perform your best. And frankly, it may be the last fitness book you ever need to read.

Praise for Muscle for Life

"Mike Matthews is one of the most informed, intelligent and experienced fitness gurus on the face of the planet, bar none. His books are full of practical wisdom advised by his years of time in the trenches, his vigorous research and his hours upon hours of time interviewing experts about what works and what doesn't when it comes to optimizing not only your fat loss and muscle gain, but also your ability to stay in the fitness game for life."

"I read each and every one of Mike’s books, and you can't go wrong with Muscle for Life."

Ben Greenfield

"Muscle for Life is a breath of fresh air. Instead of passing fads and overhyped biohacks, Matthews gives us what we need: the time-tested principles and practices that have been shown to work."

Alex Hutchinson

“Read this book, implement its teachings, and you’ll never look back. With your health and fitness fully under your control, your body, and then likely your life, will never be the same.”

Dr. Spencer Nadolsky

"You don't just read Muscle for Life—you do it, and you get the body you’ve always wanted. It's never too late to get into the best shape of your life, so this is a must-read for anyone at any age who wants to lose fat, build muscle, and get strong . . . for life."

Mark Divine

Muscle for Life is meticulously researched, clearly written, and utterly practical. Matthews has created something special here.”

Strauss Zelnick

How does Muscle for Life differ from Mike’s other books?

There are millions of guys and gals in their 30s, 40s, 50s, and beyond who are overweight, out of shape, and deeply unhappy with how they look and feel, and who don’t know what to do about it.

Many of these people have tried and abandoned many diet and exercise programs and swallowed pills, powders, and potions galore, and now, they’re afraid that nothing will work for them—that they’ll never get the fit, lean, and strong body they really want.⁣

Tens of thousands of these guys and gals have found their way to my books Bigger Leaner Stronger and Thinner Leaner Stronger, and while those books can work fantastically for people of all ages and circumstances, they’re more suited to younger, injury-free folk who want to eat and train like lifestyle bodybuilders.⁣

What about everyone else, though? ⁣

What about the gym-shy 45-year-old who’s never lifted a weight in her life but still wants to improve her body composition, health, and longevity? ⁣

What about the 35-year-old with a lot of weight to lose who isn’t ready to start squatting, bench pressing, and deadlifting heavy loads?⁣

What about the 65-year-old who needs a gentler and joint-friendlier way to get fitter, leaner, and stronger?⁣

Muscle for Life was tailor-made for these people and the many others like them—an a-to-izzard guide to gaining muscle and strength, losing fat, and getting healthy, at any age, regardless of where they’ve been and where they are.⁣

Should I read Muscle for Life if I’ve read Bigger Leaner Stronger or Thinner Leaner Stronger?

It certainly can’t hurt.

There’s plenty in Muscle for Life for readers of Bigger Leaner Stronger and Thinner Leaner Stronger to like, love, and rub all over themselves, including . . .

  • New details on anti-aging strategies that actually work (according to science)
  • New thoughts, tools, and tactics for winning in the “inner game” of getting fit
  • New meal planning methods that allow you to control your calories and macros without a scale and measuring utensils
  • New training programs for men and women that form the perfect stepping stones into the Bigger Leaner Stronger and Thinner Leaner Stronger programs
  • New supplementation protocols specifically for golden agers
  • New premade cutting and lean gaining meal plans for men and women

That said, if you're an advanced weightlifter who has mastered the fundamentals and is looking for new and interesting ways to eat and train, Muscle for Life isn’t for you. Beyond Bigger Leaner Stronger will suit you better.

Is the Muscle for Life program right for me or should I follow Bigger Leaner Stronger or Thinner Leaner Stronger?

Put simply, Muscle for Life is a smooth and gradual onramp to my Bigger Leaner Stronger and Thinner Leaner Stronger programs.

Therefore, Muscle for Life will work best for you if . . .

  1. You’re in your 40s or 50s or older and are new or relatively new to strength training.
  2. Or you have a lot of weight to lose (25% of body weight or more) and are new or relatively new to strength training.
  3. Or you want to start doing strength training but don’t feel ready for heavy barbell training.
  4. Or you’re fit and want to brush up on the fundamentals and find simple ways to improve your diet and training regimens.

Our "No Return Necessary"
Money-Back Guarantee

If you don’t like something of ours, guess what happens next?

No, we don’t request you deliver it to a PO box in the Gobi Desert by carrier pigeon. Nor do we ask you to fill a cursed inkwell with orc’s blood and demon saliva and then use it to complete reams of return forms written in ancient Cyrillic script.

We just . . . wait for it . . . give you your money back. Holy moo cows. And that means you can say "yes" now and decide later.

Free Worldwide Shipping & Returns

Many companies use shipping and handling fees to increase their profit margins, but here at Legion, we hate profits, so our shipping is free!

Okay, so we do dig on profits, but we also go in for happy customers, and free shipping works like gangbusters. So, if you live in the United States, your order ships free regardless of order size, and if you live elsewhere, your order ships free when it’s over $199.

Why the restriction on international orders? Unfortunately, shipping abroad is very expensive, and if we didn’t require a minimum order size, we’d lose a lot of money. But! We're also hustling to improve our international logistics and will be passing our savings along to our international customers.

Also, if you don’t absolutely love our stuff for whatever reason, we don’t request you deliver it to a PO box in the Gobi Desert by carrier pigeon.

We just . . . wait for it . . . give you your money back. No returns. No forms. No nonsense. Holy moo cows.

That means you can say “yes” now and decide later. You really have nothing to lose.

Clinically Effective Doses

Many ingredients in supplements don’t have any scientifically validated benefits, and many ingredients that do are often underdosed to the point of irrelevance.

That’s why we only use the choice ingredients and precise doses shown to be effective in peer-reviewed scientific studies.

Clinically Effective Doses

You need more than great ingredients to make great products—you also need proper doses. That’s why we use the precise doses of ingredients shown to be effective in peer-reviewed scientific studies.

100% Natural Ingredients

“Natural” doesn’t always mean “better,” but in many cases, natural ingredients are superior to artificial ones for various reasons, including purity, safety, and efficacy.

That’s why all of our ingredients in all of our products come from plant and animal sources, including sweeteners, colors, and flavors.

Made in USA

If you want to ensure the supplements you’re swallowing every day are safe and effective, you want products produced in the USA.

That’s why all of our supplements are made in America in NSF-certified and FDA-inspected facilities that operate in accordance with the Current Good Manufacturing Practice (cGMP) regulations.

Lab Tested

Did you know that supplements can contain dangerously high levels of toxins like lead, arsenic, and cadmium?

That’s why we test every ingredient of every supplement we produce for heavy metals, microbes, allergens, and other contaminants and ensure they meet the strict purity standards set by the FDA.

Naturally Sweetened & Flavored

While artificial sweeteners may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health.

That’s why all of our supplements are naturally sweetened and flavored and contain no artificial food dyes, fillers, or other unnecessary junk.

Science-Backed Ingredients

Many ingredients in supplements don’t have any scientifically validated benefits. That’s why we only use choice ingredients shown to be effective in peer-reviewed scientific studies.

No Chemical Junk

“Natural” doesn’t always mean “better,” but in many cases, natural ingredients are superior to artificial ones for various reasons, including purity, safety, and efficacy.

That’s why all of our ingredients in all of our products come from plant and animal sources, including sweeteners, colors, and flavors.

Security Check

Please click the checkbox below. We apologize for the inconvenience.

Some pre-workouts are all-natural. Some contain high-quality ingredients. Some provide clinically effective doses. But only Pulse checks each of these boxes.

Pulse doesn’t just “contain natural ingredients''—every ingredient is naturally sourced from plants and animals. Pulse contains no artificial or synthetic substances of any kind.

Every serving of Pulse contains 15.1 grams of active ingredients that have been shown to be safe and effective in peer-reviewed scientific research.

Every active ingredient in Pulse is backed by published scientific studies that show benefits in healthy humans.

Pulse contains no harsh stimulants that wind you up and burn you out. Instead, it contains a 1:1 ratio of caffeine and L-theanine, which produces a smooth energy rush and comfortable comedown.

We carefully examined 508 pages of scientific research to find out exactly what should and shouldn’t be in a pre-workout drink.

Every bottle of Pulse is guaranteed to provide exactly what the label claims and nothing else—no heavy metals, microbes, allergens, or other contaminants.

While these types of chemicals may not be as dangerous as some people claim, studies suggest that regular consumption of them may indeed be harmful to our health. And that’s why we don’t put any of them into our products.

Before you buy a sports supplement, you should know that it's clean, safe, and transparent. And that's exactly what Labdoor's third-party testing and certification means.

It's hard to know for sure, but this probably makes Pulse the most-popular all-natural pre-workout supplement in the world.

"No Return Necessary" Money-Back Guarantee

If you don’t absolutely love this product, just let us know, and we’ll give you a full refund on the spot. No forms or return necessary.

Labdoor Tested for Purity

100% Natural Ingredients

This product doesn’t just “contain natural ingredients’’—every ingredient is naturally sourced from plants and animals. This product contains no artificial or synthetic substances of any kind.
