Instead of it saying 'awesome' or 'stay consistent!' etc. Let the coach choose what comes up on this screen. It may also be nice to change the 'thumbs up' cartoon to our own image.

As an example. In line with my branding of clients getting ready for hiking season, It might display a picture of a mountain and say 'Epic workouts mean epic views!' or a picture of hiking boots and say 'You are ready for any adventure now!'

This would be a fun added layer of personal branding.
