This would be excellent! Then when needed to substitute an exercise you could simply search by muscle working

For every workout that your trainer sets, allow for a muscle diagram of the body to show which muscles it is working.

A picture or name of the targeted muscle group for each excercise. This might make it easier to find a substitute machine or excercise if needed.

With each exercise performed, allow a comment next to that individual workout so client can report where they feel the workout in their muscle and if it hurts them at all.
