Are you bored with steady state cardio? Running at a constant rate on a treadmill or a cross trainer gets boring and repetitive. Try the various Fartlek intervals.
The most popular one is the Gershler Fartlek.
After a five minute warm up use 30 second work phases.
Stride hard for 30 seconds, rest (light jogging) for 90 seconds. Decrease the rest period by 15 seconds each interval.
Your intervals will be as follows:
30-90, 30-75, 30-60, 30-45, 30-30, 30-15.
As you can imagine, the intervals become more difficult towards the end with very little recovery time. That's why it goes back to 90 seconds recovery each round.
Three rounds of this is a good aerobic workout.
