If you are using log-cards (on a PM3 or PM4) you can setup workouts for a crew as follows:
1. Insert a log-card in your machine.
2. Setup 1-5 workouts and save as favourite(s).
Then, for each machine your crew is using:
3. Insert the log-card.
4. Go to log-card utilities.
5. Select copy all.
Repeat steps 3. - 5. for each erg you are setting up.
When you come to row, tell your crew to select the workout from the "custom" menu.
This sounds more tedious than it is ... it's actually quite useful.
You can only store 5 workouts per logcard but, if you purchased 10 logcards, you could store 50 workouts and you would not need to pre-program (steps 1. & 2.) again.
