Here is a challenge that is being presented over at Fitocracy. It is called the Spark challenge and it lays out like this: (it was design to be able to do anywhere, but I have adapted it to EA Sports Active 2)

The routine as described at Fitocracy: (Do the routine in 4 circuits with 30 second rest between exercises and 90 second rest between each circuit)

Body Weight Squats - 8 to 10 reps
Push-ups - 5 to 8 reps
Plank - 15 secs
Jumping Jacks - 15 reps
Reverse Lunge - 6 reps per leg
Glute Bridge (Hip bridge) - 10 reps

The routine adapted for EA Sports Active 2
(suggest doing this in easy or medium level...you tough workout warriors can try this on hard...you will feel it in the morning.)

Perform 4 circuits of:
Squats (used 'medium' for 12 reps)
Push-Ups (used 'easy' for 10 reps)
Plank - (used 'medium' for 30 secs)
Jumping Jacks (used skipping on 'medium' for 65 reps which is kinda similar to doing about 32 jumping jacks)
Reverse Lung - (used 'medium' for 20 reps (10 reps per leg))
Glute Bridge (used Hip Bridge on 'medium' for 12 reps)

This can be dialed in as a custom workout. If you add 4 warmups and 4 cooldowns this will take about 32 min. to complete.

Now go ahead and Have-at-It and let me know how you feel afterwards. My chest muscles were sore for about 3 days after my first try...I probably did not stretch enough that day.
