14 Easy Ways to Track Your Health and Understand Your Body Better

Plus, the Moment feature offers guided meditations and mindful breathing to help you stay centered throughout the day.

Apps

For starters, there are plenty of free and low-cost apps that help you track your health and wellness:

• Apple's Health app tracks everything from what you eat to your fitness to your period cycle. See how your cholesterol or blood pressure or weight has changed over the years or review your exercise activity for any given day.

Body Scans and Tests

From genetic insights to full-body MRIs and 3D scans, these advanced tools offer a deeper look at your health, far beyond the usual yearly checkup.

23andMe

This at-home saliva kit gives you a deep dive into your DNA — no lab visit required. Just spit in the tube, send it off, and in a few weeks you’ll receive personalized reports on your genetic predisposition to certain health conditions. According to 23andMe, 76 percent of users reported making healthier lifestyle choices after viewing their results.

Vo2 Max

Vo2 max measures how much oxygen your body uses during exercise — and it’s considered one of the best indicators of cardiovascular fitness, metabolic health, and overall endurance. You can take this test at select gyms or holistic health clinics (just search “Vo2 max testing near me”). During the test, you’ll wear a mask and heart rate monitor while running on a treadmill or cycling, as the equipment tracks the oxygen you inhale and exhale in real time.

DEXA Scan

A DEXA scan is a diagnostic test — similar to an X-ray — that measures your bone density and helps assess your risk for fractures or conditions like osteoporosis. But it goes beyond bones: DEXA can also break down your body composition, including lean muscle mass and where fat is distributed. Why does that matter? Research from the University of Oxford suggests that fat stored in your hips, thighs, and butt may actually lower your risk of heart disease and Type 2 diabetes, while excess belly fat is linked to a higher risk of obesity-related conditions. In short: knowing where your body stores fat can be just as important as knowing how much..

Fit3D Proscanner

The Fit3D ProScanner captures a full 360° view of your body in just 40 seconds. This high-tech body scanner measures everything from body composition and circumference to posture, Basal Metabolic Rate (BMR), and your Body Shape Rating (BSR). It even shows how your stats stack up against others in your age and gender group. You’ll typically find Fit3D scanners at gyms, fitness studios, and wellness centers.
