When I first heard about heart rate variability (HRV), I was expecting it to be yet another lame “biohacking” gimmick.
The pitch is by analyzing the rhythm of your heart beat with special software, you can gauge how stressed your body is and adjust accordingly.
For instance, if you wake up and your HRV indicates your body is overstressed, you may want to save the heavy squat or deadlift workout for another day, or if your HRV has been off for several days in a row, it might be time to deload or take a diet break or get a little more sleep.
Again, it sounds like very fake news, but lo and behold, there’s good evidence of its validity. This is why high-level athletes have been using it for years, and now that the technology has become cheaper, it’s becoming more popular among recreational athletes too.
In this episode with HRV expert Dr. Mike Nelson, you’re going to get a crash course in HRV, including how to measure and track your HRV, what lifestyle factors affect it most, how to use it to regulate your training, and more.
Let’s dive in.

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.

Some popular pre-workouts are all-natural. Some contain the right mix of 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 supplement.
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.
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.
