About Norwegian 4x4 HIIT - Myworkout
Myworkout 4x4 is the cardio exercise solution for adults who want a time-efficient way to live in good health with freedom from lifestyle diseases. Brought to you by the creators of the Norwegian 4x4 method. Just over 30 minutes of exercise, twice a week, is all it takes. • Prevent common lifestyle diseases such as Diabetes, Parkinson's, and Arthritis to name a few. • Based on established and peer-reviewed science. • Measure and improve your VO2 max with accuracy far superior to current smartwatches and close to that of a calibrated lab test. • Import workouts from Apple Health, Fitbit, Polar, and Garmin. NOTES Guided Norwegian 4x4 workouts are a Premium feature. A monthly recurring premium subscription is required for premium features and is available as an in-app purchase once you have registered an account. The subscription will automatically renew each month and will be charged through your app store account unless canceled at least 24 hours prior to the end of the current period. You can turn off auto-renew at any time from your app store account settings. Cancellation of the current active subscription period is not allowed. If you are eligible for a free trial period, payment will be charged to your app store account as soon as it has expired. If not, then it will be charged at confirmation of purchase. Find the full terms and conditions, and our privacy policy, at http://myworkout.com/terms-and-privacy/. Patients with cardiovascular disease should consult a physician before engaging in high intensity interval training. The app uses your phone's GPS to track your position during use. Continued usage of GPS running in the background can dramatically decrease battery life. Myworkout 4x4 can be used to both export activities to and import activities from Apple Health.
