It would be great if clients can check off the individual exercises as they move through the work out each day, like a to do list. This would allow trainer's to see which exercises clients are doing consistently and which may need to be modified, exchanged, or removed. It would further be helpful for clients to be able to input when they do something extra or replace an exercise on their own. For example if a client is to use the elliptical and one isn't available in the gym so they use a treadmill it would be great if they could log that in the fitness plan. This can all be messaged to the trainer but that makes it difficult to manage and keep track of.
