cardio?

[kickinit]

So you think your HR should be higher while doing cardio (aerobic exercise) than while lifting weights (anaerobic)? I want to see you at 90% of your maximum HR and see just how long you can go. Again....cardio (for fat burning purposes) is NOT SUPPOSED TO BE HARD!!!

I said try 90%, of course no one without dropping dead can do that. Yes I think while doing your cardio your HR should be higher, otherwise whats the point if you can get it with weights?

I do cardio for heart health more then fat burning, I do alot of fat burning just pumping iron. I dont think 80% is hard on the bike which is where I do it, and I hit 90% several times when I ride as well.

HINTS* IMHO

Because weight lifting is considered anaerobic and glycogen is the preferred fuel source for this type of activity. Low intensity cardio is aerobic and will burn the higher ratio of fat than lifting weights. The OP did state "for fat burning purposes". Had he asked what is optimal for conditioning and heart I might have suggested he do his cardio at a higher intensity.

Yeah I just always considered CARDIO being for high end conditioning and heart conditioning. I agree with you man, dont get me wrong. I did say there at the begining reply 60-70% is the fat burning section, just IMHO I dont think of that as cardio. Just my opinion..
