Know when to train, how hard to train & when to rest in order to optimise health & fitness.
Make your training safer and more effective by using the ithlete heart rate variability (HRV) app to choose the best times to train and improve your performance.
Getting the right balance between training & recovery is often a challenge, even for experienced athletes. It makes sense to use this app, which removes the need for guess work or complex calculations from your training schedule. By judging the right balance of training load and recovery you will reap the benefits in your fitness levels. Using the ithlete HRV app every morning will give you accurate data to be able to quickly and easily measure your daily fatigue and recovery levels.

The many benefits of using the ithlete HRV App are:
• Optimise fitness
• Manage recovery
• Enjoy guilt-free rest days
• Avoid overtraining
• Prevent injury
• Tracking long-term progress
• Improve health, fitness & performance

How It Works
Training is all about stress and recovery and a hard session will lower your HRV. By using the ithlete HRV app to monitor training stress daily you can adjust sessions according to your body’s current readiness to train, improve and perform.
Simply take a 1 minute measurement every morning and follow the colour coded training recommendation; train as normal, train light or take a rest day.

The human heart is a naturally great barometer for measuring your physical and mental condition. Heart beat intervals vary when you are resting (many people do not know this) and HRV captures this valuable information. Increased HRV is linked to good health and a high level of fitness, whilst decreased HRV is linked to stress, fatigue and even burnout. This is why measuring HRV is a must for all athletes and sportspeople, whether professional, or keen amateurs.

Please Note:
The ithlete HRV app requires additional hardware. Users will need either a heart rate monitor chest strap and ECG receiver or an ithlete Finger Sensor. Both are available from www.myithlete.com/products.
Please see the ithlete website for a full list of compatible models and purchasing options.

Please also note that this HRV app is NOT a heart rate monitor app, which people use during exercise. The HRV app is an app that uses heart rate variability to indicate your state of fatigue, recovery and readiness to train following a 1 minute morning measure, and it is not used during the actual exercise.
