I disagree on the pushups and situps every day. Your body needs rest, not only the muscles, but the joints and tendons as well. I've known quite a few people to fall into the trap of doing either of those exercises daily and they often times end up with (temporary) shoulder, elbow, or lower back issues.

Planks and other low stress core exercises are great daily workouts. Also cardio, like running, swimming, or biking.

This is a good point. Your muscles adapt to load faster than your joints. If you feel any tingling in your elbows with push-ups, take a couple days rest.
