 When they're coming in, you've got to withstand the hit. It's like football practice in a way. Do you hit by one of those heavy waves? And then as it goes back out, the undertow, you've got to fight that. So you're going to get a workout. I mean, I'm aching. I've been working out like crazy now for almost eight months. But I hurt in places today that I wasn't before I went. So it was really awesome. How did you enjoy yours?
