walking and jogging 5.0 mph???

I think it's very rare and difficult to really be able to walk 5.0 mph. I'm tall and have long legs and I'm a fast walker, but on the treadmill I can only keep up walking at 4.5 mph for so long. If I upped it to 5.0 mph, I know i'd be doing little skips to keep up with the treadmill! So believe what the treadmill tells you, as far as mph, not the workout video. As far as calories go, I don't know if walking and running a mile give you the same calorie burn, but when you're walking you have a lower heartrate over a longer period of time so it's probably not too far off.

I have wondered this exact thing...I have to run to keep up with the treadmill @ 5.0 and I do mean run... the video is fast paced but I am def not running. I have actually said out loud how could it be that pace when on the treadmill I can't hit that pace. So, I totally understand your question but I don't have an answer I hope someone can help!

I tried to walk on my tredmill at home with the Biggest Looser walking workouts just to see how it compared. I was keeping pace with their workout and it was supose to be a 1 mile workout for each program, but while logging on my treadmill I only traveled just over 3/4 of a mile on 3 different 1 mile workouts. 1 was 0.75 miles 1 was 0.85 miles and 1 was 0.72 miles so averaged 3/4 mile.
So not sure how they figure 1 mile workout from since it is a video walking in place.

It's very possible that your treadmill is calibrated wrong. There is a way (you can look it up online) to test to see if your treadmill is actually reading pace accurately. Unless you have a high-end treadmill, it may be reading slower than you are actually going.

I can easily run a 11:00- 12:00 mile outside, but on the treamill if I keep my heart rate where I would have kept it on a run outside, my treadmill says I'm going at a 14:00/mile pace. Seroiusly! I know I'm not going that slow.

RHerrin5 - I always wondered about this too...but I just don't want to knock a good thing lol So I just log it like I calculated the miles with the timing and got 5.0 mph...so I don't know. If you figured it out, you know I want to know too

Bump any other opinions?? I guess it's working, but I'm not sweating like I do with the treadmill... am I still burning the calories??

There are two separate issues here:

1. Is the "accuracy" of your video the same as the accuracy of the treadmill in terms of speed. I think the answer is obviously "NO". The video is describing a "speed like" effort, but, as you have found out, it does not resemble the real energy cost of walking 5.0 mph.

2. Is there a difference in energy expenditure between walking 5.0 mph and running 5.0 mph? The answer is: probably, but not always. As walking speed increases, the gait becomes less and less efficient, to the point where it can actually approach the energy cost of running at the same speed. For most people, that is a moot point, since they cannot walk fast enough to reach that level, but 5.0 mph is getting into that "gray area". Because of differences in gait and walking style, there is no way to accurately calculate the energy cost (i.e. calories burned) of walking at speeds greater than 4.2 mph. It's more of a rough estimate.

I can barely walk at 4.0mph because it's too fast for my calves. I usually walk at about 3.5-3.7mph and run at about 5.8-6.4mph. Don't worry about speed, though.

PLEASE TELL ME HOW YOU ARE LOSING AT A GREAT PACE AS I WANT TO DO WHAT YOU AR DOING????? Thanks for the help.

Hi, My understanding is that the steps and the speed doing them is what makes up the 5 mile (for instance)..Also a trainer told me that if you jog for say 45 minutes and walk for 45 minutes you burn more running, however if you run a certain distance and walk that same distance it takes longer to walk it but it is the same in calorie burn because you are moving longer...Hope that makes sense?

No, this is not true. If I run 1 mile, 1 burn ~85 calories. If I walk a mile I burn about 55 calories.

Okay, so when doing the 12 min miles, then I'm really supposed to log those by that? I'm doing the Leslie Sansone 5 Mile Fat Burning walks. And on here it's jog, 5.0 mph 12 min miles. It just doesn't seem like I'm really burning that many calories. Great if I am, but maybe I should get a HRM... so confused.

You aren't. But don't obsess about it -- and don't get an HRM just for that reason, because it won't be any more accurate. For the Leslie Sansone video--multiply your weight in kilograms by 4 or 5. That's your calories burned per hour. Multiply that by the hours worked (e.g. .75 for 45 minutes, 1.25 for 75 minutes, etc) for calories burned during the workout.

That's as close as you need to be.
