Start your journey to better health with a free two-week trial of the Myworkout 4x4 app.
Designed to provide you with evidence-based training guidance, it combines science and technology to accurately measure your VO2 max.
Your VO2 max reveals more about your physical health than any other parameter we know of—more than blood pressure, cholesterol, and BMI combined. The app estimates your VO2 max and biological age with high scientific precision by assessing how much work you can perform during a standard 4 x 4 interval session. This can be done outdoors, on a treadmill, or using equipment.
Once the app knows your capacity, it becomes personal and will guide you on what smart activities are best for you. Experience faster progress in your training and personal motivation. The app can also be integrated with third-party services to enhance your training experience.
