Fun way to start exercising

So I am a member of pinterest and frequent the fitness section. They have a lot of small workouts that take 20-30 minutes and range in difficulty. (An example of one would be: 50 crunches, 30 squats, 10 pushups, 30 leg lifts, 30 sec imaginary chair) For the longest time I've wondered how I can incorporate them into my routine, and decided on a new fun game.

I listed them by number and put numbers in a hat and every day I pick out a number and do the corresponding exercise. It keeps me on my toes and prevents me from being lazy and picking the easiest one.

This works well for me because I am the last person to want to work out, and get bored easily with exercising. It adds some suprise each day.
