Vital Data May Be Eluding Your Current Fitness Tracker

Many of us know exactly how many steps we climbed yesterday morning. We even know our heart rates at each increment of that morning’s routine. We also know our pulse rate and how many miles we covered—all leading to a determination of today’s personal goal. Does this sound like you? 

Your fitness tracker—whether an Apple Watch, a Samsung Gear S2, Amazfit, Xiaomi, Polar, or Biostrap —gives you a plethora of information you could never even come close to recording yourself on a spreadsheet after huffing and puffing your way back to your computer desk.

The Missing Links

Still, many of these trackers are not telling you things you should know to fully inform you of your fitness status. Why? Because most of them can’t read between the lines, essentially. However, some trackers, such as the Biostrap, strive to do just that, and not settle for only the formulaic or surface indicators of your fitness level.

For example, while a few fitness trackers are catching onto its importance, HRV or heart rate variability—the elapsed time between each heart beat—attracted prime attention from Biostrap engineers. Why? Because HRV can pick up clues about your routine: Is it too strenuous for your current health status? Are you losing more than you are gaining? Is your routine indeed on point to meet your fitness goals?

The answers all lie in the time elapsed between heart beats and whether the period between heart beats remains consistent or variates—the latter indicating a desirable level of fitness.

According to an article in Wearable, an online tech site on wearable data processors, HRV can be used by doctors to help detect diabetes, hypertension, and problems with the immune system. According to the article, your HRV can hinge on several peripheral factors. These include the time of day, your general body position, as well as your mental, physical, and emotional experiences of the day or week.


So, do you want the full story from your fitness tracker? Then your tracker must have the ability to read between the lines, like the Biostrap. You can simply use the following checklist when comparing fitness trackers.


This commonly recorded data can include number of steps taken, distance traveled, or even laps in a pool. Formulas exist for the ideal number per routine, but these standards don’t account for the aforementioned conditions surrounding or affecting the individual’s mental and physical health status at the time—those influences that HRV can help identify.


Another very common piece of data that wearables record and indicate is the pulse, detected in most cases from a sensor in the tracker. Again, however, this doesn’t account for the resting heart rate or HRV.


A fitness tracker that detects how much blood and oxygen reaches your extremities can help to determine your ability to fully recover from a workout and be ready for the next one.

Body Temperature

Trackers apply a built-in thermometer that tracks the surface temperatures of your skin. When not working out, it can detect abnormal variations in body temperature which can serve as a disease or illness indicator.

Blood Sugar

Trackers that can measure glucose count in the skin fluids can help you determine how much your diet is affecting your fitness level. You can try to change your dietary pattern or content depending on your recorded glucose count.


Any worthy tracker will be able to detect your algorithms when at rest and asleep. Utilizing a constant metering of heart rate, the type of sleep you are experiencing—i.e., light, deep, and REM—can be determined. This can help you look at areas of your daily routine that might need some adjustment, such as exercise, stress, hours at work, or waken hours. 


Some of the leading fitness trackers and, as mentioned, newcomer Biostrap are beginning to include the variations between your pulse or heart beats into your fitness equation. This much more customized data can better determine your fitness level as it pertains to your individual health. It helps to break down the one-shoe-fits-all data inherent in such conclusions as the healthiest heart rate range or ideal number of steps per day.

Calorie Counts

Your fitness tracker can also help you keep an estimated calorie count for each day to help keep you on track to obtaining your fitness goals. The user must accurately input certain metrics such as height, weight, and age in order for the fitness tracker to use a formula for calculating calories consumed and burned. Each Biostrap fitness tracker comes with this calorie feature to give you a healthy baseline throughout your day. 

Make a List…and Check it Twice!

Wearable fitness trackers and all associated technology will no doubt continue to evolve. So, when searching for your ideal fitness tracker, be sure to ask about the tracker’s ability to monitor each piece of data on the aforementioned list and any additional data that can relate to your individual physiology, such as stress levels and the ability to recover after workouts or extremely exhausting activities. Research reviews and studies online. Fitness trackers, such as Biostrap, are designed to fully serve the fitness needs that best suit your individual lifestyle. Learn more about Biostrap today.
