Duration vs. Intensity question...

[geetey]

For weight loss, which is more appropriate? A high intensity but shorter cardio workout (20 minutes) or a less intense longer cardio workout (45 minutes).

A little background....
Before joining the Fitness Center, I was doing 3 or 4 mile WATP tape @ 5 times a week. I have been WATPing around 5 months.

Now I have been working out every other day faithfully at my dh's fitness center with an on-hand trainer always available. Sept 29th was my 1 month anniversary of adding weight training to my routine. I currently do 30 minutes of interval training on the elliptical and then 2 sets on each weight machine.

The problem?
I have gained 4 pounds - to be expected when adding weight training, I understand - but they won't go away! No significant change in my measurements either. I am doing WW at home (double checking my info on fitday.com) so my food intake is appropriate.

The question...
Joey (the trainer) keeps increasing the intensity level of the elliptical. If I can do 30 minutes, she says I am not working hard enough and need to increase the intensity. My argument is that I am looking for weight LOSS and need longer cardio workouts so my body has to go to my stored fat. Does anyone know which is correct? I am enjoying the workouts but I would like to see some results!

Help! What should I be doing to stay fit *and* lose weight?

Terry,
When I was actually successful at losing weight, it was by increasing the intensity on the elliptical. At first, it didn't seem to be working, but what I was told was that by adding muscle, I was increasing my metabloism, which helps burn more calories. It did work. (but, I also added 10 min's to my circuit for good measure ) Good luck, whatever you decide. I'm glad that you are so committed!

Keep the Faith!
Tracy

I have heard that the "best" it to inverval train. Meaning you do moderate exercise with BURST of high intensity.

But if you had to pick high intensity for 20 mins or moderate for 45 my guess is that the 45 minute is the better one.
