On our immediate roadmap, an option to create your own exercises isn’t something coming as we prefer to add these exercises ourselves. The reason being is that we give a value to each muscle group that is used in each exercise, and implement that into our algorithm. We like to keep this streamlined, whereas it might have a different relative value to you and another user. This would in turn make the algorithm relative and not necessarily accurate for the app. This isn't to say that it can't be or won't be done in the future, but for now, we ask that users who want exercises added, to please send them to us by using our Submit a Request form with Exercise Request in the subject line. If the requested exercises gain enough traction amongst the queue, we will add them into our program.
In addition, we have received requests asking to implement activities like rock climbing, yoga, soccer, basketball, etc. This has been discussed amongst the Fitbod team and we'd love to integrate it into the app but it is a bit tricky from a quantitative standpoint since movements can be highly variable session-to-session and would hinder the muscle recovery accuracy. Again, this isn't to say that it can't be or won't be done, but it is projected that will take some time.
We get A LOT of exercise requests so please keep in mind that we simply can't include ALL of the requests we receive. We do consider each one and track how often they are requested. When decisions are made with regards to new exercises, the Fitbod team considers safety first and overall usability by our users as a whole.
