By using the Viking 4x4 app or this website, you agree to these terms.
Not medical advice
Viking 4x4 provides fitness timing, guidance, and educational content. It is not a medical device and does not provide medical advice, diagnosis, or treatment. High-intensity interval training pushes your heart to near-maximal effort. Consult a physician before starting any high-intensity exercise program — especially if you have a heart condition, chest pain, high blood pressure, or have been sedentary. Stop exercising and seek medical attention if you experience chest pain, severe shortness of breath, or dizziness.
Assumption of risk
Exercise carries inherent risk. You use Viking 4x4 at your own risk and are responsible for training within your own capabilities. Heart rate readings depend on your device's sensors and may be inaccurate; never rely on the app for medical monitoring.
Intellectual property
The Viking 4x4 name, marks, app, and site content are protected by applicable intellectual property laws. Scientific studies cited on this site belong to their respective publishers and are linked as references. Experts and researchers referenced are not affiliated with Viking 4x4 and do not endorse it.
App Store
The app is distributed through the Apple App Store and your use is also subject to Apple's standard licensed application terms.
Disclaimer of warranties; limitation of liability
The app and site are provided “as is” without warranties of any kind. To the maximum extent permitted by law, Viking 4x4 is not liable for any indirect, incidental, or consequential damages arising from use of the app or site.
