The One Tool Everyone Should Use To Train Smarter


Whether you’re picking up a workout routine for the first time ever, a high school track star, or a cyclist about to embark on a Grand Tour, the most important objectives for an athlete are the same.


Endurance. Speed. Efficiency. 


Maybe you’re competing in a race, competing against yourself, or just trying to figure out how to do a whole set of pushups without collapsing. Whatever the case, everyone wants to improve and be the best they can be as quickly as possible. But how can you tell if you’re training efficiently? 

By monitoring yourself with a pulse oximeter.

Why It Works


Pulse oximeters measure blood oxygen saturation, or how much oxygen is really getting carried in your bloodstream. All the bent-over wheezing in the world won’t help you if that air’s just getting wasted. 


A pulse oximeter can tell you just how much oxygen your cells are actually getting – and that can be a HUGE help for all kinds of athletes. 


Endurance and HIIT


High Intensity Interval Training, or HIIT, is all the rage these days. But even if you’re doing a normal exercise, like running or climbing stairs, you’ll still know it’s high-intensity by that tell-tale breathlessness. Some experts call this “The Talk Test” – if it’s high-intensity, you’re not going to have it in you to talk; all your air is going to supporting your muscles and your heart. 


This is some of the most effective exercise for endurance and weight loss. But notice the catch there – all your air has to be supporting your muscles and your heart. If you’re not getting enough air, you’re not getting the benefit of the workout, and may in fact be putting yourself in danger if your blood oxygen saturation drops too low. 


Blood oxygen levels commonly drop after a high-intensity workout. By using a pulse oximeter, you can make sure to work out when your oxygen levels are high enough to give you the full benefit, so you’re not working hard for nothing. 



Recovery is crucial for increasing athletic performance over time. Without proper rest in between workouts or training, you’re just shooting yourself in the foot.


But how can you know if you’re resting well?


Sometimes people “just know.” But bodies can be hard to interpret. If you wake up after a hard training session and don’t feel right, are you the type to go ahead and work out just as hard anyway, or the type to play it safe and give yourself a day off just in case?


With proper monitoring, you don’t have to guess. Just check your saturation levels. Are they below 95%? Maybe a light workout is a better idea. Below 92%? It’s a good day to stay on the couch. 


How It Works


Pulse oximeters used to only be used in doctor’s offices, but it wasn’t long before smart athletes caught on to how useful they are and started ordering them to keep in their gym bag.


The oximeter works by harmlessly emitting light through the finger. That infrared light’s transmission changes based on how much oxygen there is in the blood, so the amount of light that gets through to the other end tells the oximeter how much oxygen there is in the blood. 


Like all gadgets, oximeters vary in quality. If you pick one at random off a pharmacy shelf, don’t be surprised if it doesn’t give you the same reading twice. But a good pulse oximeter will be accurate and give you a wealth of information you wouldn’t get otherwise.

The PeakLife360 oximeter is FDA-approved, high-precision, and fast. In seconds it will give you not only your oxygen saturation but also your pulse rate and pulse strength. All you need to do is put it on your finger and press the button.
