do you walk or run on treadmill??

I used to be a pretty hardcore runner but after herniating my disc a year and a half ago I primarily walk.

I honestly can't stand to walk on a treadmill, unless the weather is an issue, which is rarely the case in SoCal. But I sometimes preferred running on a treadmill because I could control more variables than I could outside. When I was doing marathon training I knew the distance I needed to run each day, the pace and the incline so it was just easier to get on a treadmill and knock out the miles. Some days it would just be too distracting dealing with traffic, people walking dogs and bikers, etc.

I walk...2.7 mph, no incline. Thats the best I can do. I do walk for at least 1 hour, sometimes 2, 5 days a week.

Brisk walking on an incline on the treadmill is a fantastic workout.

This how I have lost most of my weight I spend a hour on it, I am at the max incline now so now Im working on building the speed up on the incline.

There is no "better". There is "what matches your fitness level and workout goals".

There is a difference between activity and exercise. Any activity will burn calories and can contribute to a calorie deficit that can help you lose fat. Technically, you don't have to become extra fit to lose fat (but it sure helps). So, someone just tryng to lose weight can achieve success at any speed. The main thing is that if you are walking at a recreational pace, you need to put in more time (since the calories/min is usually fairly low).

To improve fitness, one must work at a minimum intensity level. So, your exercise intensity needs to match your fitness ability. Someone who regularly runs at 7 mph is not going to see fitness improvements walking at 3.5 or 4.0 mph. So if the goal is to improve fitness while losing weight, then walking will not be a good choice for everyone. Walking at 4.0 mph burns less than 50% of the calories as running at 6.0 mph.

Now a treadmill (or hills in general, but treadmill inclines are more consistent) adds another dimension. Increasing inline can signficantly increase intensity to the point where it can equal some running itensities. You have to learn how to walk up a steep hill (it's a little tough on the back at first) and you CANNOT hold on to the handrails (or else you negate a huge part of the intensity), but it can be a great, low-impact calorie burner. As a rule, most people trying this will be better off lowering the speed down (even below 3 mph) and learning to deal with a 10%-15% incline first. Then start increasing speed. You can change speeds and inclines to build a workout with lots of variety.

I started walking on treadmill for 15 min a dayLittle by little I went faster, farther, and then at an incline. After 9 months I began to run. Slowly I increased with interval training and after 6 more months run 5-7 miles a day. I like the idea of it taking less time to work off the same number of calories. My hubby prefers to walk at the incline . I have been told that the incline is bad for my knees as well as the running is bad for me knees. My knees feel fine and my doc approves of the running, so I am going to keep at it!

Warm up for 5 mins at 3.0mph then jog at 5.5mph for 3 miles. A few months ago I'd walk for 4.0 then run 8.0 for about a min, and I really liked the results of high interval training, but it really took a toll on my left knee. :-s

I walk on the street and walk on the treadmill when the weather isn't cooperating.

I walk at 4.5mph at a high incline for 4-5 minutes then I sprint at 8.7mph at a little incline for 30 seconds and repeat for 20-25 minutes.

I usually run on the treadmill. I especially love doing HIIT on the treadmill.

Both. Mostly about 4 mph. With some incline.
