5 Prevayl Metrics You Need to Know to Get Started
When it comes to smart sportswear, you’d be hard-pressed to find one as accurate and detailed as Prevayl. From basic to advanced performance data, the Prevayl App gives you everything you need to optimise your time and effort at the gym.
If you’re new to Prevayl, you need to know the metrics, what they represent and how they’re measured to get the full potential from your kit. Here, we explain five metrics in the Prevayl App to help you start a new chapter in your fitness journey.
TRGT (Training Goal Tracker) is an integral part of the Prevayl App, which empowers you to track your fitness progress.
Your TRGT is based on a TRIMP Score, which is a widely used measure of exercise intensity, based on heart rate, in both scientific research and sport. It quantifies training load and stress placed on you by a single number – think of it as your fitness progress quantified numerically.
You may have seen a similar intensity score in other fitness trackers, but no one does it like us. We use an algorithm which is not currently seen in any other fitness tracker out there to tailor your TRGT to your fitness level, thus creating a metric unique to you.
Doing a BodyCheck™ every morning when you wake up enables us to provide you with personalised training advice based on how recovered your body is. After each BodyCheck™, you’ll be presented with a result which indicates how recovered you are.
The BodyCheck™ sets itself apart from other fitness trackers by measuring your resting HR and HRV in both lying down and standing up phases to identify signs of under recovery and overtraining. Whereas other fitness trackers, which typically only measure your resting HR and HRV during sleep (lying down phase), can only detect under recovery and not overtraining.
Below your BodyCheck™ result is a daily training recommendation on how to approach your training: whether you should train, rest or progress. This is the outcome of a big decision tree consisting of your BodyCheck™ result, training history and experience level to ensure you reach your fitness goals safely. And all of this only takes three minutes.
3. Training Zones
Training Zones show you how much time you spent in each Training Zone throughout a workout. They’re a visualisation of your five heart rate zones based on the intensity of training relative to your maximum heart rate (max HR), the fastest rate that your heart can beat during maximal effort exercise.
There are five Training Zones, each of them corresponds to a different percentage of your max HR:
- Zone 1: 50-60% of max HR (Light effort)
- Zone 2: 60-70% of max HR (Moderate effort)
- Zone 3: 70-80% of max HR (Moderate to high effort)
- Zone 4: 80-90% of max HR (High effort)
- Zone 5: 90-100% of max HR (Very high effort)
To get the most accurate data out of Training Zones, make sure your personal max HR is kept up to date – to do so we recommend performing a FitnessCheck every four to six weeks. Having the wrong max HR could mean the difference between one Training Zone and the next, which leads to inaccurate ratings of workout intensity.
Exercising using this metric can help you hit specific intensity targets, which makes it the perfect workout companion for all you heavy HIITers out there who want to fully optimise the benefits of your workout. For HIIT to be most effective, your work phase should reach at least 85% of your maximum effort or Training Zone 4. Likewise, should you decide to participate in active recovery on a rest day, your HR should not exceed Zone 2 – and Training Zones give you this insight at a glance.
4. Body Load
Body Load is a metric that monitors your physical stress indicators. A first mover in the sportswear space, Body Load collates data from your current workout – including the time you’ve spent in specific Training Zones and the estimated change in your core temperature based on your HR – to give you the ability to steer clear of overtraining and injury, ensuring that you stay engaged throughout your fitness journey.
Body Load is designed to help you train safely by maintaining an intensity that isn’t putting your body under too much stress, which in turn increases the risk of injury. For example, if you’re advised to rest after a BodyCheck™, you should aim to keep your Body Load in the green zone as anything yellow or red is too much for a rest day.
Accumulative information is taken every second then delivered to the Prevayl App in a live chart, clearly illustrating the total strain your body is under over the course of the session. This shows you the risk of overtraining and injury in real time, so if you’re the type that goes all out at the gym, this is one metric you need to pay attention to in order to progress safely.
5. Heart Rate
Heart rate tracking is a standard feature on most fitness trackers and wearables. However, they’re not exactly known for their precision and their accuracy diminishes during exercise, which renders wearing them in workouts pointless.
Prevayl, on the other hand, is connected clothing that negates the need for a chest strap or additional fitness trackers. Lying within our smart t-shirts, tanks and sports bras is all the tech you need to capture the most precise measurement possible directly from your heart and level up your workout.
Prevayl's HR is calculated from our clinical-grade ECG, processing over 1,000 data points per second – four times more than any other wearable on the market. The insights are delivered in a simplistic UI during your workout, giving you an insight into your current beats per minute (bpm) and where it sits in relation to Training Zones.
There’s So Much More to Prevayl
Prevayl is connected clothing that bridges the gap between you and a stronger you. Elite athletes wear it to push their limits – now you can, too.
