Make a list.
Since you don't have to worry about watching traffic, the treadmill is the perfect place to focus on form. Run through a full-body checklist, beginning at the top. Think: Tall; Rhythmic breathing; shoulders relaxed; relaxed arms with elbows bent at 90 degrees; hands loose and swiping your hips; legs moving like the blades of scissors, eating up space with each stride; foot strike, heel-toe, heel-toe.

Fun and games.
Try a few mind games to carry you through a run or power walk. How about a Fartlek workout, an odd word that means speed play in Swedish? Say to yourself: For the next three minutes I am going to run at six miles per hour, then I can walk at a comfortable pace for the next three. Then, for the next two minutes I will run at 6.2 mph before walking another three minutes again. And so on until your workout is complete.

More games.
If the Fartlek method is too freeform for you, come up with a definite structure beforehand. For example, try a pyramid: Increase your speed 0.1 mph every minute until you hit the halfway time of your workout, say 15 minutes. Then for the next 15 minutes decrease the speed 0.1 mph every minute. It is a great workout that probably burns more calories than your usual "run of the mill" program.

It's on the schedule.
You wouldn't dream of missing your regular 8:30 Thursday meeting with your supervisor, or the season finale of E.R. But a workout? It always gets pushed to another time slot. Commit. Put it in your Palm Pilot or Week-at-a-Glance -- in INK.
