What if shocking your muscles with electricity helped them grow and develop faster?
What if it could reduce exercise-induced muscle damage and help you recover better from your workouts?
What if it could straight up make you stronger?
Well, this is why people buy and use electrical muscle stimulation (EMS) machines.
They believe they’re an easy and safe way to gain muscle and strength faster and boost post-workout recovery.
You might want to believe, too, but you’re skeptical.
On one hand, the whole approach sounds pretty scientific, and haven’t we seen various professional athletes hooked up to these machines?
Then again, some scientific studies aren’t worth the paper they’re published on and some athletes will beat the drum for anything that brings a paycheck.
EMS machines are expensive, too, so there would need to be a considerable payoff to justify the cost.
Well, when you take a cold, hard look at the science, here’s what you learn:
EMS isn’t silly pseudoscience, but it’s also not as great as the machine manufacturers would have you believe.
Yes, it’s safe, but no, it’s not going to dramatically impact muscle growth or recovery.
That said, it doesn’t mean you shouldn’t necessarily give it a go. You should just have the right expectations.
In this podcast, we’re going to break down what EMS is, how it works, and what science has to say about its effectiveness.
Mike Matthews is the founder of Legion as well as the author of several award-winning fitness books, including Bigger Leaner Stronger, Muscle for Life, and The Shredded Chef.
His simple and science-based approach to building muscle, losing fat, and getting healthy has sold over a million books and helped thousands of people build their best bodies ever, and 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.
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.

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.

Clinically Effective Ingredients & 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.
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 with Globally Sourced Ingredients
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.
