The Fitbit Charge and Fitbit Flex are getting a revamp with new designs and features.

The all new Fitbit Charge 2 and Flex 2 effortlessly track your most important health and fitness stats, with new sleek looks and an experience that is even more engaging, motivating and personal to help you reach your goals.

“Over the past nine years it has been our ability to innovate on both design and utility, and our deep understanding of what consumers want that has made us the leading global wearables company1,” said James Park, co-founder and CEO of Fitbit. “Flex quickly became the best-selling tracker2 on the market as one of the first wearables to successfully merge fitness and fashion; we’ve revolutionized Flex 2 by making it swim-proof and adding more features in a design than is 30% smaller than the original. We broke new ground with Charge HR by making wrist-based heart rate accessible to millions of users around the world, and we’ve done it again with Charge 2, giving users a snapshot of their cardio fitness based on estimated VO2 Max.”

The new Fitbit Charge two has an updated version of the brand's most popular watch with two new features powered by your personal heart rate, an estimated VO2 max and guidance on how to improve your fitness and guided breathing sessions called “Relax”. The beat-to-beat changes in your heart rate determine your personalised breathing rate for each experience. Two- and five-minute sessions display real-time heart rate visualisations, animations and vibrational cues to help you align each inhale and exhale with the guide, and find moments of calm throughout your day. Research has shown that developing a long-term guided breathing practice can have health benefits that include reducing stress and anxiety, and lowering blood pressure.

The new watch will also include more real-time, actionable exercise stats right on the display so you can make instant adjustments during your workouts and improve over time, with multi-sport modes for specific workouts like runs, bike rides, weights, yoga and more, plus post-exercise summaries and detailed reports of your activity in the Fitbit app.

Link your fitness wristband with the GPS in your smartphone to provide even more precise and actionable real-time stats, like pace and distance when you’re running, while recording a map of your route in the app.

The new Interval workout mode guides you in alternating periods of high-intensity exercise and recovery to maximise workouts like circuit training so you can stay focused on your workout.

Advanced sensors make tracking your whole day effortless by automatically capturing all-day activity and sleep. SmartTrack automatic exercise recognition records everyday activities like walking, running, elliptical, and more with ease, plus reminders to move motivate you to stay active throughout the day.

The modular design and easy-to-read tap-sensitive display is four times larger than the previous Charge HR, letting you personalise a look that fits your style with interchangeable bands and clock faces – while keeping you connected with the smart notifications you need most.

The watch retails at £129.99 and can be purchased via Fitbit’s website here.

Mio’s new app claims that it brings activity IQ to your heart rate that can lengthen your lifespan. Every fitness band collects data, but now Mio gives meaning to the data it collects which can increase your life by up to 10 years.

Mio claim: ‘ Your heart rate is the single-most accurate reflection of your body’s response to physical activity, which is directly linked to your health. PAI translates your heart rate data and personal profile information into one simple, meaningful metric: Your PAI score.’

PAI=100. Your goal is to finish the week with a PAI score of over 100 and if you do so your helping to maintain a good health profile and increase your lifespan.

In order to start using their Personal Activity Intelligence users need to download the PAI app and then use their Mio wearable during a training session. PAI then uses this data to give the user instant feedback and a PAI score.

What's the score based on? PAI uses your personal profile containing your age, weight, gender, height, maximum heart rate, resting heart rate and feedback from your training to develop your score.

Is PAI scientific? The algorithms used in PAI are based on activity data from over 60,000 people, collected over a 20 year span

Pai is simple to use, every activity you do, as long as it raises your heart rate, contributes to your PAI score.
