Interval Training

First of all, you are NOT burning 1200 calories. That treadmill is whack.

When I do interval training, I add up what I'm doing at each speed and enter it seperately.

I jog for 8 minutes at 6.5
Run for 45 seconds at 10.0
Jog for a minute at 5
(repeat the last 2 lines 3 more times)

So I log it like:

8 minutes at 6.5
4 minutes at 5
3 minutes at 10

I do a lot of interval training and I just log the time and an average mph for the duration.

I have been doing intervals on my treadmill. Generally running at 6 mph and walking at 4 mph. There is no way to log interval training in the exercise section, as far as I can see. So I average it out and say I jogged at 5 mph, just so I can put something in the database. Does anyone else know how to do this or am I missing something?

Also, my treadmill says I burn about 1200 calories during my 25 minutes, but according to the exercise section it's says I've burned about 150 calories. Are treadmills generally that far off?

Thanks in advance for all answers!

Create your own exercise, entitle it something like "Treadmill: interval training" input the amount of minutes you were on there and input the calories. I would say those calories were way off, to burn 1200 calories is something a half-marathon runner would use up in two hours. Unless you are very overweight and unfit, it is virtually impossible to burn such a huge amount.

If you do not have an HRM, as a rough guide, one mile = 100 calories - this is a rough guide though, but it is much more accurate and yes, machine calorie burns can be way-off.

You are more than likely burning between 250-300 for that 25 minutes.

Before I got a HRM I logged how many minutes I did at each speed. Like the second commenter said after the OP. But I like my HRM much better!!!
