I personally type each session with a client beforehand. At the top I have Blocks for: Client name; workout focus; experience; Goals; Injuries; Workout days; date; time.
the lower section across the top I have blocks that say: Exercise, Set 1-4, and the a small section for notes.
I also make all my programs a circuit training so they do one set of each exercise and then rest.
On the back its one big section of work out comments. I fill that with any and everything I can. If they mention they are going to their kids recital I write it down there so I can ask them how it went the next time I see them. If they huff over an exercise I write it down. I fill this section with everything I can.
I can send you my template if you would like. Just e-mail me. [email protected]
