Relations between similar tables?

Relations between similar tables?

Relations between similar tables?

The title may not be accurate... but here goes:

I have a workout DB that allows me to enter workouts (workouts contain exercises), meals (meals contain foods), and schedule the workouts and meals in a schedule table (links a meal or a workout to a schedule record with a date and time).

Here's where I'm having trouble:
I want to track my progress as far as weights and reps. This means a seperate "Instance" table for the workout items. When I add a workout to the schedule, the workout items instance portal should populate with the exercises in that workout simply by entering a workout ID. However, I don't see that as possible via my design. I have to create new "instance" records, and copy the workout IDs into them. This is not ideal, and I feel like I'm missing something here (there has to be a better way). I know a but about DB design, relationships, etc, but can obviously use some guidance.

Any help is greatly appreciated.

RE: Relations between similar tables?

Not knowing your whole structure, I would say that you have to add an exercise in the exercise table, and link that to a workoutID.
If the exercise doesn't fall into a workoutmodel
you have to create a new workout and an exercise.
