First you need check if Exercises is null and check if is greather than zero.
After this you need use the Length of array for the max value of random function.

 
    public void ExerciseButtonPressed()
    {
        if (null != Exercises&& Exercises.Length > 0)
        {
            exerciseText.text = Exercises[Random.Range(0, Exercises.Length)];
        }
    }
