Every fitness tracker collects huge amounts of data in order to help people improve their performance. The rate at which your heart beats, the quality of your sleep, and the amount you eat and drink are all tracked by these sensor-laden Wearables. When it comes to planning workouts, I haven't found anything that gives advice like a live human coach.

People and their bodies are not always predictable. Even the pricey, sports-focused platforms that mix hardware and software can only give you personalized guidance. I want to know if a watch will tell me if I have a stress fracture. I only have half an hour between meetings, but my program calls for 60 minutes. Does skipping my strength workout count?

When watchOS 9 becomes available to the public in July, it will signal the arrival of a lot of new fitness features for the Apple Watch. The ability to measure running power is geared towards elite athletes. Even casual runners should benefit greatly from the ability to study their vertical oscillation, create custom workouts with their own distance and time intervals, or pace themselves against their own routes. The Apple Watch might be the best sports watch of all time. There were rumors of battery life improvements.

The ability to measure vertical oscillation, stride length, and ground contact is the newest feature. Improving your economy during physical activity can be accomplished with the help of these three measures. Most people will run a lot farther and faster if they move forward with each step instead of bouncing up and down and taking shorter strides.

If you own an Apple Watch, you will no longer need to buy a separate device and download a separate app to get the data you want. Apple uses machine intelligence to find out how much your body is moving up and down and when your feet are hitting the ground. I have to wait to test watchOS 9 to see if it's true.

The ability to create workouts is an improvement. It is possible to suggest productive workouts with running watch software, but following those workouts can be very demanding. Recommendations can be hard to fit in with my busy schedule because they don't map well to my real-life running habits. You will be able to create your own running workouts with your pace, distance, time, and heart-rate zones. There will be new notifications for zone and cadence training.

Like most runners, I run a variety of routes that vary in speed and finish on different surfaces. I can take into account the slow warm-up and cool-down jogs to and from my local high school track where I do interval runs in the evenings if I want to keep my heart rate low. The Apple Watch will allow me to run faster.
