Fitness trackers have significantly evolved since the days of simply counting 10,000 steps.

Today, you can choose from rings, watches, bands, and other tech gadgets to help you stay fit, manage your sleep, monitor your heart rate, count steps, track calories, and monitor various health aspects.

Research conducted by Sutter Health, a not-for-profit integrated health delivery system based in Sacramento, California, indicates that fitness trackers can aid not only in getting fit but also in managing chronic conditions like diabetes and maintaining optimal heart health.

With so many options available, selecting the right fitness tracker can feel overwhelming. The key is to determine what you want your fitness tracker to accomplish.

For example, I use a basic Garmin Vivofit model to count steps and stairs. However, most fitness enthusiasts will want their tech to offer more features. Here’s a roundup of tools to help you enhance your health through fitness tracking.

Choosing the Right Fitness Tracker

When selecting a fitness tracker, consider the type of wearable you prefer and how you intend to use it. Ask yourself the following questions before making a purchase:

How do I plan to use this fitness tracker?

Some trackers are designed for specific activities like swimming or running. Think about your primary use for the tracker—do you want it to monitor sleep, calories, steps, or miles?

Research from UCLA Health, affiliated with the David Geffen School of Medicine at UCLA, shows that fitness trackers paired with personalized feedback and encouragement from health coaches and medical professionals can lead to “sustained improvements” in sleep and exercise. These features might be available through apps connected to some devices.

Simply wearing a device may not yield long-term fitness results, but it can support efforts to focus on health. UCLA’s research found that “integrating wearable devices into more comprehensive, personally tailored behavioral interventions improves compliance and behavior change.”

How much can I afford to spend?

There are budget-friendly fitness trackers that collect basic data, and even free step-counter apps available on your phone. The more features you want in a fitness tracker, the higher the cost.

Do I care about fashion or just functionality?

My Garmin is slim and black, but I can switch the band to purple or blue depending on my mood. I once owned a rose-gold Fitbit because I loved the color.

 Some friends prefer fashionable and attractive fitness watches. Consider what constitutes fashion for you and how important color or band size is to you.

How does it charge?

I charge my tracker through my laptop, which can be inconvenient when traveling. Others come with their own charging stations.

 Decide how simple or complex you want the charging process to be, and consider how long a single charge will last.

Is it compatible with my phone?

I believe a fitness tracker should be compatible with your phone, especially since most trackers have paired apps or websites. There are many quality fitness tracking devices available that are compatible with both Android and iPhone.
