Hi,
I would like to create a challenge (although I would be the only participant) based on a personnel workout that I would like to do everyday.
I do not find the option. I can create a challenge based on one exercise or e predefined workout, is it possible to do so based on my personnel workout?
Hey Santiago 
Not using the Challenges feature in the app no. But for all intents and purposes, there’s nothing stopping you from doing exactly what you want to-i.e. set yourself a challenge to do your own workout every day, many of us do exactly that when we have our own group or individual challenges.
Thanks Ben.
Yes that´s what I thought. It has an aditional step and do not allow others to join.
Is what I would do once finished my february challenges
