What kind of cardio?
I know cardio is like a double edged sword for weight training, but what works best to burn the least amount of muscle when trying to burn fat?
The only way that doing cardio will "burn muscle" is if you are starving, and your fat stores have already been consumed. So whatever kind of activity that you enjoy, or at least hate least is the best cardio for you. Why not try to incorporate your cardio into your strengthening routine? The next post will probably be from Tim suggesting "complexes" or "metcons," which would fill that bill nicely.
Cardio can cause consume muscle if it is long duration. Anything over about 1 hour could have a negative impact of your muscles. Extreme long distance certainly will have an impact. 2-4 miles/day, a few times per week should not have a negative impact provided your nutrition is sound.
Any cardio that has a strength or anaerobic component, like complexes, HIIT, sprints, etc will preserve muscle more than long steady state cardio.
The fat-burning zone is merely the range in which the majority of calories burned comes from fat. It is not the zone where the most fat is burned. Intensity is important. You will burn far more calories at higher intensities including more from fat. You should try to exercise in the highest intensity level you can sustain, which will normally be the cardio zone. I believe the "fat-burning" zone was invented for people who were so out of shape the couldn't get to the cardio zone so the fat-burning zone was created so they would think they were still accomplishing something.
HIIT type training should put your heart beat well above the cardio zone for brief periods several times in a session. The training effect on your aerobic system is higher than more moderate activity, and as said earlier, will preserve muscle better. The post exercise calorie burn is higher as well and this would make this a better fat loss program than moderate cardio. It is very hard and you should work up to it progressively. Doing too much too soon could lead to overtraining.

Re: What kind of cardio?
If you want to drop fat, look to your diet first. No matter how well thought out your exercise program is, if you eat junk/fast food, sugary sweets and refined starches (white flour and white rice) your results will be minimal.brook011 wrote:I know cardio is like a double edged sword for weight training, but what works best to burn the least amount of muscle when trying to burn fat?
There is a wealth of dietary information on this site'sDiet and Nutrition Forum to help you get started.

Thats in interesting idea stu, maybe there is science behind it or it is just a standard to help out of shape people.The fat-burning zone is merely the range in which the majority of calories burned comes from fat. It is not the zone where the most fat is burned. Intensity is important. You will burn far more calories at higher intensities including more from fat. You should try to exercise in the highest intensity level you can sustain, which will normally be the cardio zone. I believe the "fat-burning" zone was invented for people who were so out of shape the couldn't get to the cardio zone so the fat-burning zone was created so they would think they were still accomplishing something.
Well there is plenty of science to what Stu is talking about in terms of higher intensity vs this so-called "fat burning zone". Cosgrove gives plenty of studies in his article "The Heirarchy of Fat Loss". Stu may be right in that it was invented for that purpose; i.e get them into something useful for a transition into a higher intensity thing, but a couple of things. Doc Cooer popularized aerobics back in the 70's, and in fact was working with target heart rates, but it was for overall cardiovascular heart health, and yes, some people were dropping some lbs, but he didn't create it for that specific pupose. Then early on in the 80's the fitness craze took hold, and somehow, this target heart rate was being touted as a fat burning zone, and as Stu pointed out, it will in fact do that, but only for the duration of the exercise, wheres the activity contaiing an anerobic component caused the system to keep the "reved up" so to speak, long after the actual exercise period was over.

It also doesn't really matter whether the body is burning fat or carbs, it's the total calories that matter anyway. I wish I did know the origin of the "fat burning zone". I know the logic I described is the reason and every machine has it on it.
Here are a couple af articles that "get it".

Here's an example of bad information that is out there:

Note that this has been reviewed by a medical review board.
It's kind of funny that another writer on the same site does know her arithmetic:

Tim's dead-on with his reply. Here is a great article that cites several studies on the matter.

Okay guys, first attempt here at HIIT -
Stretched
Warmed up for 3.0 minutes medium pace, 3.5spd on treadmill.
Ran 2.0 minutes at 8.2spd on treadmill.
Cool down 2.0 minutes, 3.5spd.
Ran 2.0 minutes at 8.0spd on treadmill.
Cool down 2.0 minutes, 3.5spd.
I did intervals of this for about 22 minutes total treadmill time, on my last sprint, it was like an 8.9spd. A few people looked at me weird but the actual work felt good, usually only cooled down long enough to allow my heartrate to relax, and then kick it back up again. Is this right? I've never done this before so I wasn't sure. Thanks guys. Oh and the treadmill goes to 10, so 8-9 is like 5 1/2 minute mile pace on this thing.

Haha I could imagine people looking at you wierd thats hilarious. I can understand why though. Most would be thinking what the hell is this guys problem stick to a damn speed haha. Unbeknowest to them he's doing HIIT. While the constant treadmill lovers who run off muscle daily sit there at a decent speed for two hours he gets a better workout in 22 minutes. Thats awesome. By the way someone said sprint for thirty seconds? I cant sprint for 15 seconds. haha sprint = all out run right?
Corless @Sprint = all out run?
Yep. Might be hardrunning, but I used to do it on a bike, 30 sec on, 30 sec light pedaling in a lower gear. Not that difficult, although it did get me beathinglike a charging Rhino. 15 - 20 mins used to feel like it was going to kill me.Although a good start up would be 5 mins of light to moderate cadence, and start with only 5 mins of thes intervals, then a 5 min "cool down " of moderate to light pedaling.
