The secret isn't the "4:30" part, it's the "do the thing" part. You can almost certainly squeeze something into 30 minutes of your day, somewhere convenient. So pick the convenient time and do that.

I don't live somewhere with sidewalks, so running is out for me. (Plus I don't like it much.) I do a basic circuit with pushups, lunges, and pull-ups, first thing in the morning, while the coffee is still brewing. It's my "I don't feel like fussing with a proper routine" bare minimum, but it's enough. Then I have breakfast, shower, and get on with the day. It takes no actual equipment (anything that supports your weight is fine for pullups) and costs nothing but time.
