Step ups

Step-ups are a great way to get exercise, and all you need is something to step on. You can buy a step-up block or use a piece of wood, or really anything under a foot tall that you can step-up onto.
Try doing these for 30 minutes a day. Step-ups can be done in a variety of ways. Front steps, side steps, backward steps, try anything you like.
You can do as little or as much as you want. 10 minutes a day to 2 hours a day. It's a great alternative to other forms of cardio like walking or running.
Mountain Climbers

This is a more advanced exercise than step-ups. If you're pretty fit you can do them as cardio. Do them in a timed manner, ie. a minute straight, when you get more fit you can do them for 5 or 10 minutes at a time. Go for 3 timed sets and add time as you go.
Here is a video demonstrating the mountain climber exercise:
