Exercise more effectively and evaluate your progress with scientific precision.

Getting results from workouts might be simpler than you think. Myworkout GO looks to the scientific consensus on physical exercise and cuts through the clutter of workout fads and overly complicated training routines. Instead, it focuses on what actually works and can be done by anyone.

At the heart of Myworkout GO, is a precise way of evaluating your physical fitness. By assessing the amount of work you can 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.

Your VO₂max is reduced by an average of 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, just two 4-by-4-minute interval workout 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 workout. Just select the type, start the exercise, and follow the instructions.

• Use it outdoors, on treadmills or on exercise machines.
• Use it to track regular walks, runs, or exercises.
• Full workout log.
• Heart rate feedback *

• Weekly activity score.
• VO₂max and biological age evaluation.
• Statistics and graphs.
• Heart rate guidance. *
• Exercise and instructional videos.

* Requires a compatible heart rate monitor.

The methods used by Myworkout GO are based on the 25 years of world renowned research from professors of medicine, Jan Hoff and Jan Helgerud, from the 2015 Nobel Prize winning Faculty of Medicine at the Norwegian University of Science and Technology – NTNU.

Nice, but completely lacks Apple Watch support

Overall great application, but it would need Apple Watch support to reach it’s full potential. Having to register elevation gain and splits manually, weighs the whole experience down.

It does not support integrated Apple Watch heart rate detection, and falls short compared to Nike Run Club and Nike Training, which each have their own WatchOS apps and offer native heart rate support. WatchOS also has integrated support for VO₂ calculation via the Workout app on Apple Watch.

Testing was done using Apple Watch Nike+ GPS & iPhone XS Max.

Appen klarer ikke å lese pulsen fra pulsklokka. Dette, selv om den klarer å hente data fra pulsklokkeappen.
- Tenkte jeg skulle ta en intervalløkt.
Startet med seks minutters rolig jogging. Etter sju minutter oppdager jeg at appen er ute av stand til å gi et lydsignal når oppvarmingen er ferdig og det første draget skal starte. Draget derimot, det klarte appen å starte på uten meg.
Etter ett minutts forsinkelse var vi i gang, appen og jeg.
Da draget var slutt prøvde appen seg selvfølgelig med å ikke si fra at draget var over, men jeg lot meg ikke lure flere ganger.
Det begynte å regne og usikker som jeg er på om min nye iPhone 11 Pro er vanntett, valgte jeg å plukke fram telefonen med jevne mellomrom for å sjekke status.
Nedover til det siste draget begynte appen å spørre om jeg ville slå den av, hver gang jeg tok den opp. Det var det siste jeg ville.
Rett før jeg skulle til å begynne på det siste draget hadde appen avsluttet økta på egen hånd...
Kunne ikke startes igjen og nei, tre drag er for lite til at jeg kunne få noen tilbakemelding eller evaluering på formen.
Leste nettopp at oppfinneren av denne appen har tjent ti millioner.
Om jeg skal slette denne appen, spør du?
Gjett om!
