The truth about being “fit”

The problem — when it comes to fitness — is that too many people just focus on building muscle or losing fat. But those are only two parts of a much bigger picture!

Fitness is about optimizing systems of the human body to work well together. That means understanding everything from optimal sleep quality and hormone regulation to joint health.

And years of research have taught us this: fitness is usually oversimplified. For many people, it is all about muscle and fat, weights and cardio; but to solve a puzzle as complex as optimal fitness, hammering the same routines over and over will not work.

You need to figure out your personal bottlenecks among the six main fitness factors and take advantage of the most recent evidence to remove them, or even turn them into strengths!

The six main facets of fitness:

  1. Joint health

    Healthy joints allow your body to deal with the strains of exercise, sports, and normal everyday activities. A lack of pain should be your everyday state!

  2. Sleep

    Deep, restful sleep lets your body recover from the day’s activities and wake up energized.

  3. Muscle and exercise performance

    Muscle is one of the two obvious fitness factors, but optimal muscle mass isn’t just for looks: it helps keep testosterone levels high and lets you enjoy physical activities.

  4. Fat loss

    Fat is the second obvious fitness factor: high body fat leads to lower testosterone, lower self-esteem, and accelerated aging.

  5. Testosterone

    Optimal testosterone levels have far-reaching benefits, including more muscle, greater mental clarity, and better mood.

  6. Cardiovascular health

    Cardiovascular health grows in importance as you age: improving it now will not only boost your recovery but also help prevent future heart complications.

It’s all interconnected:


To truly be fit, you need to address all the factors

Here’s a real-life example: your knees.

Every pound of excess weight you carry means about 4 pounds of extra pressure on your knees when you walk, 8 when you run. In other words, if you’re just 10 pounds overweight, that’s 40 to 80 pounds of extra pressure on your knees with every step you take!

And yet, if you’re overweight, the first thing friends told you was likely to run, either outside or on a treadmill. Miles of running every day. Hours of running each week. “No pain no gain!”

That’s a recipe for disaster.

Instead, you could alternate between running, swimming, and lifting, so that your efforts don’t all put pressure on your knees. You can also decrease your knee pain with smarter nutrition, supplementation, and body positioning at work.

The Fitness Guide gives you a comprehensive approach at fitness, realizing that you should not just improve one facet, but all facets.

We also provide you with free lifetime updates to the Fitness Guide. Originally launched in 2018, we have spent over a thousand hours updating it with the latest research.

Nutrition research never stops — we are always learning something new, and we make sure to pass it on to you.

The Examine Fitness Guide is the best of both worlds: it ensures you have a handle on the big picture of interconnected fitness, and it is meticulously research-backed

  • Low-fat or low-carb? Which diet is healthier, and which works better?
  • Can you lose fat both quickly and sustainably? And without extreme dieting?
  • Which one ability is most correlated with achieving long-term fat loss?
  • Does eating six meals a day actually promote muscle growth?
  • In which two cases might BCAAs help you more than regular protein powder?
  • How could you burn upward of 30,000 extra calories per year while typing on your computer?
  • How important is LDL-C, compared to LDL-P or cholesterol particle size?

  • Which vitamins and minerals should you take together and which separately?
  • Why is the standard treatment for joint pain so problematic?

Who benefits from the Fitness Guide?

Athletes who have hit a plateau in their fitness journey

You’ve tried high-reps, low-reps, pyramids, drop sets, supersets, jogging, HIIT, and all the rest. So why aren’t you getting any faster, stronger, leaner? Are there supplements that could help you break through your plateau?

We’ll see which ones are best supported by the evidence; we’ll even see which forms to take, in what dosages, and in what combinations. But more importantly, we’ll examine fitness factors that are routinely neglected yet are often the real causes behind a plateau.

People who want to get (back) in shape

This is the year you’re getting back in shape! But where to start? Are there supplements that could help you lose fat and give you more energy to exercise? Certainly, and here again we’ll see which which forms to take, in what dosages, and in what combinations, based on the evidence.

But supplements are the cherry on the fitness cake; there are many other factors to consider first. So many, in fact, that fitness can seem an overwhelming puzzle! But we’ll break it down and guide you.

Whether you’re overweight and find dieting and exercising difficult, or you’re just out of shape and wish to start an exercise regimen, we’re here to help. Whatever your age, it is never too late to get fit!

Not just how to lose fat, but how to keep it off.

Not just how to pack up muscle, but how to stay pain-free.

Not just how to improve your sport performance, but how to be fit enough to enjoy life and your favorite activities at any age.

Whether you’ve just turned 20, are in your 40s, or have retired and want to stay healthy, our Fitness Guide can help.

We’ll explore dietary habits, sleep hygiene, body positioning, and yes, even supplements — which forms to take, in what dosages, and in what combinations. All based on the latest evidence.

We are the experts other experts rely on.

For John Berardi and his team, Examine is unbeatable value

When I was a grad student, it was easy for me to keep up with the latest research in exercise, nutrition, and supplementation. Of course, staying current was essential to my development as a scientist, writer, and coach. Nowadays, though, with the epic rate of research output in our field PLUS everything going on in my life (i.e. parent of four young children, founder of two businesses, author, competitive athlete) staying up to date feels impossible.

Jennifer Sygo uses Examine to get “the lay of the land” quickly

Examine’s updates help me to stay on top of current research on supplements and diet trends. Their in-depth summaries are a great way to get “the lay of the land” quickly and efficiently.

John Meadows trusts Examine so he can focus on his clients

I tend be really busy these days which makes it really challenging to keep up with the latest research. If you know science, you know that reading and evaluating research is not as simple as reading an abstract. There is a great deal of nuance involved. Put more succinctly, I just don't have the time to do it justice.

When James needs trusted nutrition information, he turns to Examine

I turn to Examine.com for quick, reliable data on a whole host of health topics. It’s rare to find such guidance that is meticulously researched yet easy-to-digest, but Examine manages to deliver on both. I strongly recommend it as a trusted resource.

What is Examine and why should you trust us?


  • Examine is an independent encyclopedia on supplementation and nutrition. We’re unique because we don’t sell supplements and aren’t affiliated in any way with any supplement company. When we recommend a supplement (or say another is ineffective), it has no impact on our bottom line. Consider us the Switzerland of the world of nutrition and supplementation.
  • Since our inception in early 2011, we’ve had but one goal: to be the best source of unbiased information on supplements and nutrition. Molecular biologists, biophysicists, pharmacists, dietitians, sports nutritionists, kinesiologists … the members of our team are all accredited experts, but with very different backgrounds, so that when we review research, we get the full picture. That’s why we have over 50,000 references on our website — we’re happy to show our work.
  • This single-minded dedication to providing well-researched, unbiased information has made us the #1 site for supplement information. Over 2.5 million people visit us every month. We have over 50,000 happy customers. And when major media organizations — the BBC, the New York Times, the Washington Post, Men’s Health, and many more — need experts, they turn to us.

About Examine

Examine started because we were frustrated.

We were frustrated with supplement companies misrepresenting scientific research. We were frustrated with social media “influencers” peddling products they didn’t use themselves. We were frustrated with famous doctors and mainstream media disregarding context to produce sensationalist headlines.

This frustration drove us to create what we sought and couldn’t find:

Examine is a 100% independent company that lives or dies solely by the accuracy and usefulness of its analyses.

Since our founding in 2011, we’ve been working for you, and only for you. We don’t sell or advertise supplements and don’t accept sponsorship or donations — not from companies, not from organizations, not even from individuals. You are our sole source of income, so there is no conflict of interests: the only interests we serve are yours.

Or to put it another way, you empower Examine to keep providing unbiased information about nutrition and supplementation — two topics rife with misinformation and disinformation.

Back in 2014 Men’s Fitness called us game changers for bringing an evidence-based approach to nutrition and supplements.

In 2020, Men’s Health UK had us #1 on their Most Influential list.

Today, the hundreds of free articles on our website are read by 2.5 million visitors each month, and over 50,000 people have bought our publications. Medical doctors, dietitians, coaches, and personal trainers entrust the health of their patients, athletes, and clients to our analyses.

We are the experts other experts rely on. And like the health professionals, each time you purchase any of our publications, including the Examine Fitness Guide, you purchase thousands of work hours from a dedicated team of experts with degrees in nutrition, exercise science, public health, pharmacology, toxicology, microbiology, biophysics, biomedical science, neuroscience, chemistry, and more.
