Can I start a workout off of my iPhone to my Apple Watch since I cannot see the screen?

since my watch has gone black and the screen wont show, is there a way to "start" a workout from the phone? So my watch can track it in the background. I have no way of controlling my watch because the screen just turned black out of nowhere. but it is working in the background, can track my heart rate, can receive notifications, etc
