Amazon is no stranger to innovation. And its health wearable, Halo, keeps with that trend. Amazon has continually added new AI-powered features throughout the device’s life, and its latest addition may be the most impressive yet. Movement Health, which debuted June 30, turns your phone into a digital personal trainer.

Movement Health intends to improve functional fitness and the ability to perform everyday activities like bending and reaching. To do that, the feature takes advantage of technologies like computer vision and machine learning. Here’s a closer look.

Machine Vision Fitness Checks

The first step in using Movement Health is a fitness check using your phone’s camera and the Halo app for iOS or Android. Halo will guide you through five movements: single leg balances, overhead squats, lunges, overhead reaches, and feet-together squats. As you work through these motions, the Halo app uses machine vision to track your movement for assessment.

With the data from this test, Movement Health will evaluate your posture, stability, and mobility. It’ll then give you an overall score out of 100, along with more detailed breakdowns covering specific areas where you may need to improve. The experience is a lot like what you’d go through with a physical therapist or personal trainer. However, it’s all done from your phone.

Amazon claims this assessment is as accurate as a professional trainer. Whether or not that’s true may be debatable, but the feature’s movement scores go into surprising detail.

Your New Digital Personal Trainer

After the initial assessment, Movement Health will provide a personalized exercise program to improve your lower scores. For example, if you need to work on your hip mobility, it may recommend bridge extensions and spine rotations. Each set of exercises comes with video instructions from physical therapist Dr. Kelly Starrett.

Each set will take five to 10 minutes to complete and should be done at least three times a week. Amazon also suggests reassessing every two to four weeks to track your improvement. If you think you’ll have trouble keeping up with these exercises and assessments, the app lets you schedule reminders.

The Halo wearable and service certainly aren’t cheap, although it’s certainly a benefit to pick one up. This new feature could provide a more affordable alternative to personal training, though, and improving your functional fitness would save money in the long run.

Keeping Your Health Information Secure

Amazon made sure to mention how it provides “privacy by design” when it announced Movement Health. Since the recent introduction of Alexa to Halo raised some privacy concerns, it’s understandable why Amazon wants to reassure its customers along those lines.

To help keep your health data safe, Amazon encrypts your movement assessment videos in transit. That means someone trying to intercept things on their way to the cloud wouldn’t be able to understand it. After processing the information in its machine learning algorithm, Amazon deletes it, preventing data breaches later.

Halo may remove movement assessment videos, but it stores plenty of other health data. If you’re concerned about this information potentially leaking or want to maximize privacy from Amazon, you can delete it in the app’s settings.

Amazon Halo Keeps Adding New Features

When Halo first launched, it was an underwhelming service given its comparatively high price. Since then, it’s become an increasingly helpful tool. Frequent updates like the Movement Health feature give it capabilities you may not find anywhere else.

Movement Health is perhaps the most exciting update to come to Halo so far, and in tandem with Amazon's full-service pharmacy, you can keep your health in check better than ever before, even if you don't have insurance.

Anyone looking to improve their functional fitness could find its assessments and guided exercises helpful. As Amazon keeps bringing updates like this to Halo, it could become the leading health wearable.
