Cardio Energie

Its a ‘biggest winner’ dvd with jillian micahaels from the ‘biggest loser’ . it foucuses on the back biceps glutes hamstrings and abs. it incorporates weights with cardio interals and really gets my heart rate up.

I’ve been going to the gym for the past few months now, and I definitely feel a little more fit and stronger. I also feel like I have less body fat on me, or because I have muscle under it, to make me feel more sculpted with it.

Anyway, I’ve been going on the treadmill, and instead of running (because I have the worst endurance ever), I go on the highest incline at about 3.5mph for about 45 minutes. My heart rate stays at about 175 give or take, at that pace. My question is if that doesn’t count for cardio. My gym trainer told me that he goes on an incline because he doesn’t like running. But my friend, who’s in cross country told me that running is the only effective form of cardio along with biking, or whatever.

But I’m saying that if you do something to get your heart rate up, especially in the fat burning zone (as the chart on the treadmill indicates), isn’t that a good form of cardio?

I normally workout on random mode but have tried the cardio mode where you enter age, weight, time, and heart rate. When I do this it works well until I get about 16 minutes into the workout and then the machine increase the resistance to max and I can not make it move fast enough so it goes into pause mode.

I have now tried this on three different machines and they all do the same.

Any idea on what I am doing wrong

I mean can I just jump on to the machine and depend on my instincts to stop

or

I must use a device to monitor my heart rate.

For the days I can’t get to the gym. I just need a few that will really get my heart rate up. Good music is a must.

which one gives the best cardio results? i prefer the cross trainer which hass less impact on the feet which is best for a cardio workout to burn that gruesome fat! i like how the cross trainer provides your heart rate too
