I would like to be able to assign substitutions or alternatives for strength exercises. I have many clients who all have various equipment available to them and are at different levels, strength wise. If I could put a variety of options for a specific exercise and allow them to pick which best fits their situation that would save me a lot of time and give them more flexibility. Another example would be I program chin ups, but I have a client who can’t do them so they could look at the alternatives and select inverted rose instead.
