      Questions

      When can I start?

      Very soon. Join the waitlist and we'll email you on launch day.

      How does Chango know what I should do?

      You tell it your goal, how often you train and how much time you have. Chango picks the exercises, sets and weights, and plans each workout around the muscles that have rested. Read more: How many sets should I do to build muscle? →

      How will I get better?

      Chango makes your workouts a little harder as you get stronger, and eases off when you need it. Read more: When should I increase the weight? →

      What is the 3D figure?

      Your own figure, where each muscle glows by how much you've trained it: the more training, the brighter the glow. When the whole figure glows evenly, your training has been balanced and enough. Dim spots show right away what has been left behind. Turn the figure around and see your progress over one workout, a week, a month or a whole year.

      What if I only have 30 minutes?

      You choose how long you train, and Chango fits the workout to your time.

      What if I miss a week or two?

      No problem. After a longer break, Chango starts you a little lighter so you get back into it safely.

      Can I change exercises?

      Yes. If a machine is taken or you don't like an exercise, swap it for another one.

      I've never had a training plan. Is Chango for me?

      Yes. Chango shows how each exercise is done and starts from where you are. Read more: How to start gym training →

      What does it cost?

      Start with a 14-day free trial. After that, Chango is €9.99 a month or €59.99 a year (prices may vary by country), unless you cancel at least 24 hours before the trial ends.

      What happens to my data?

      Your workouts are stored in the EU. No ads, no third-party tracking, and you can delete your account anytime.
