Until a few years ago, interval workouts were only used by elite athletes looking to improve their competitive performance. As more and more research came to light about the benefits of this method of exercise for losing weight and improving fitness levels, interval workouts became more and more popular. These challenging workouts are great for pushing through a fitness plateau, and they are effective for rebooting weight loss efforts. I have heard folks refer to them as magic.
You should have a strong aerobic training base before incorporating interval workouts into your cardio routine. One thing I love about intervals is you can do them with just about any form of cardio. To see some of my favorite interval workouts from 2008, just
- Sprint intervals at the track
- 30 minute stationary bike workout
- 25 minute treadmill sprints workout
- A mile swimming workout with sprints
- 30 minute rowing workout
- 35 minute elliptical workout
To monitor your effort you can either use a heart rate monitor or your rate of perceived exertion (RPE). Have fun sweating.
