Target heart zone--how important?

I remember the old target zones that stated one subtracts their age from 220 and multiplies by certain numbers and that one should stay in that range to burn fat. How important is that? It seems in my target zone, it is too low and I am bored with not working out to my fullest. Any truth to this thing of targeting?? Thank you.
 
This formula is flawed at best. It never really applies to fit people. I personally don't like using HR formulas because I find they usually don't match up to my RPE(rate of perceived exertion) response. One way to reconcile RPE and HR is to focus on how you're feeling during exercise and then glance at your heart rate monitor to "assign" a number(between 1-10) to your HR. It's not very scientific, but it is more of an individual approach. If you want to use a formula, then I would suggest the Karvornen formula which takes into account your resting heart rate. I believe the formula is:
220-age -resting HR
Multiply by percentage(for example, you may want to work at 85% of your max heart rate so you multiply by .85)
Then add back in resting HR and you will get a number that is supposed to represent 85% of your max HR. Make sense?

I like your way best. I like to work out so that I sweat heavily. I don't feel like I am doing anything uless I feel like I have put myself through a hard workout. I am not overweight and in pretty good shape so I don't think the fact that I like to work it at 170-180 is too bad.
I appreciate your information and spelling errors? Who cares????

when I work out hard, as in Imax 2, I always feel really good for a few hours after the workout, I feel relaxed. Is this that runners high?
 
I also never bother with heart rate monitoring and such, and go by perceived exertion (and even then, I only *really* use that for running - if I know I'm going out for a long run, for example, I'll make sure that I'm feeling quite differently than if I'm out for a tempo run... With videos, the nature of the video sets the pace for you - I don't have to change anything.).

A number of years back I participated in an experiment to determine max heart rate, and mine was MUCH MUCH higher than what would be predicted by any of the formulas out there. So for me, using HR as a guide for anything at all, is absurd.

I honestly don't really get the point of it. Do people really scale back their effort because they notice a little number on some monitor, that is higher than they think it should be, regardless of how they feel? Or they need the HR number to increase their intensity? They wouldn't notice that they aren't working hard enough without the number?

Apparently I'm a simple gal. I work out hard. If I am feeling like I'm really overdoing it and won't get through the workout, I scale back a tad. It's a pretty easy system. :)
