By now it's almost a farce. Contestants on "The Biggest Loser" are pushed to run mind-numbing sprints on the treadmill. The contestants hesitate, saying, "I can't do it!" The trainer gets in their faces, calls them on their fears, and screams until they get back on the treadmill. Pushed to completion, the nearly-collapsed contestants develop looks of awe on their faces and praise the trainer and the show for helping them face and conquer their fears. You have just experienced treadmill sprinting, "Biggest Loser" style. And this season, it appears to be happening every episode.

So how do we mere mortals pull off this exercise without a TV crew? Is it even worth it to do treadmill sprints?

Sure, and here's an easy way to start:

• Practice jumping onto the metal runners on either side of the treadmill. Use your arms to support your weight as you open your legs to each side of the moving belt. Be sure you can do this quickly and easily, in case you need to perform this movement during the sprint.
• Increase your speed by 25 percent of your normal pace, so if you usually walk at 4 mph, jump it up to 5. If you normally run a 10-minute mile (6 mph), try running at an eight-minute mile pace (7.5 mph). Try to stay on the treadmill for 20 seconds. If you feel like you're going to fall, or if you feel dizzy, stop immediately.
• If you're successful at the increased speed, try to keep it up for 30 seconds the next time. Do two or three of these sprints during your first 30-minute treadmill workout. Over the course of the next month, attempt to increase the amount of time you continuously sprint to two minutes.
• Once you are regularly sprinting for two minutes at a time, do three or four sprints per workout.

Sprint training can be done once or twice per week. It increases your cardiovascular endurance, your anaerobic threshold and will give a little goose to your calorie burn during the workout. The sprints allow you to burn about 20 to 30 more calories a session, about the same as a Hershey's kiss!
