Similar take. The UI and lift explanations are nice but the lift selections (when even available) are a bit dubious at best. In some cases, sub-optimal, in other cases out of left field.

My personal suggestion would be to populate the data base with all the standard primary/secondary lifts (bar, dumbell, machines) and let users build their own program. Maybe have an option to suggest alternatives for any given lift.

After that is done, then maybe work out routine creation, hopefully with some general input to the developer from actual trainers.

Also agree, keep the equipment simple/standard and avoid branded machines,etc.
