Nice job! Little bit of feedback:

1. The images don't update until after the first tick of the new exercise. It would be nice if the updated when the rest screen changes to the new exercise screen with the timer and the text.

2. It would be cool if for exercises like the side plank (I think that's the only one in this set), where you hold something on each side, it gave you a halfway warning to tell you that it's time to turn over.

3. The rest period at the end isn't really necessary.

It would be nice to have a sound option, too - to just say the exercise name when it starts - so you don't need to look at your computer all the time.
