Getting results from workouts might be simpler than you think. By looking at the scientific consensus when it comes to physical exercise, Myworkout GO cuts through the clutter of workout fads and overly complicated training routines to focus on exercise that is actually effective and can be done by anyone.

At the heart of Myworkout GO is a precise way of evaluating your physical fitness. By looking at the amount of work you are able to do during a regular high intensity interval workout, the app calculates your maximal oxygen uptake (VO2max) and biological age. These are the most important measures of physical health we have today.

VO2max is on average reduced by 1% every year after the age of 20. It is however possible, with the right type and amount of exercise, to reach and stay at the same VO2max as an average 20 year old (biological age of 20) until you are in your 80s. For most people, just two 4 by 4 minute interval sessions a week is sufficient to achieve this – and if you combine it with strength training, you will further improve by increasing your work economy.

The app will guide you when performing a 4 by 4 interval. Just select the type, start the workout and follow the instructions.
