I personally feel like this is very important. Everfit currently has this feature and I believe Trainerize could benefit from it. I’ve had many clients who can’t do a specific exercise and would have to travel into the extensive library to find an alternative that is hopefully appropriate for them. If we can have a drop down and add in a regression exercise or a progression exercise for the client would make things easier for the client and the trainer. This feature can also help with automation and sending out programs. Because now the client can change the level of the workout without relying too much on the trainer. I really hope this feature gets added in sure many would benefit.
