Work Smarter, Not Harder

First of all let me say congratulations to Team Super Stars and all of the Tweightloss folks for a great first week! We lost a total of 116.1 pounds this week between 81 people!!! That is amazing!

Some of you have been asking me about heart rate training, target heart rate, wearing a heart rate monitor....etc. So, I wanted to give you my two cents about heart rate training. I always wear a heart rate monitor when training. It keeps me in tune with my body and helps me get the most out of my cardio workouts.

Most of us approach cardio exercise in one of two ways. We are either moving so slowly that we don’t elevate our heart rate much at all or we go at all out intensity and work too hard, moving our heart rate out of the maximum fat burning range. There are 3 types of fuel that we can burn when exercising; carbohydrates, fat or lean mass. Most of us prefer to burn fat. After all, one of the main reasons that most people work out is to lose weight and/or reduce body fat.

By working smarter, not harder, you can increase the amount of calories from fat that you burn during a workout. The more intense the exercise the more overall calories you are going to burn. You will also burn more calories in a shorter amount of time. But the kicker is that the higher the intensity, the less number of calories that are coming from fat. The trick is to find a happy medium where you are working hard enough to elevate your heart rate and burn fat while keeping the intensity low enough that you continue to burn fat and not begin to use your lean mass as fuel.

You also want to make sure that you are working hard enough to build a cardiovascular base and increase your fitness level.

One way to make sure you are working in the proper zone is by obtaining a measurement of your VO2 max. This is the amount of oxygen that you are able to consume per minute per kilogram of body weight. The more oxygen you can consume the heavier workload you are able to perform. This test will provide you with the proper training heart rate zones for your age, weight, height and sex.

Whether or not you have your VO2 measured, another good idea is to wear a heart rate monitor during cardio exercise. This lets you see precisely what your heart rate is during exercise. (If you have a VO2 max test, then you will know what your appropriate heart rate zone is for achieving maximum fat burn while still working to increase your overall fitness level.) Many heart rate monitors allow you to program your training zones so that you are easily able to stay in your zones while working out.

Many people are surprised at the low intensity that is required for maximum fat burning. If you are only interested in overall calorie burn then higher intensity exercise is great. It is also good, no matter what your goal, to crank up the intensity at least once a week to maintain your fitness level and possibly even improve it.

Cardio exercise is a key component to a well rounded fitness program and it will only enhance the results that you will see from consistent weight training. If you can get all pieces of the program firing at once, you will reach your goals in what seems like no time at all and you’ll do it by working smarter, not harder! That is music to my ears!

Ok, so now that you've sold me on the benefits ;) where can I find a relatively affordable one?

Thanks for the great post!

Steph - Polar is the best in the business for heart rate monitors. They have an entire range of monitors. I have the women's F11 and love it! Well worth the $150 I spent over 2 years ago. But if that is not affordable enough, they have other models as well. http://www.polarusa.com/consumer/fitness/hrm.asp

I absolute adore my heart rate monitor, but the down side is you get caught up in those calories and work harder than you might mean to.

I have a really, really hard time staying in my target heart rate zone. It always tells me to aim for 120-155 as my zone. I can hit 120 just walking up the stairs.

If I jog for ANY length of time, even just for one minute, it jumps to 175 or even 180.

I've tried to do work outs where I stay completely in my zone and I just don't feel like I've done anything more than take a light stroll.

Is it possible my O2 levels are just way off the average, or do you think I really might be working too hard? (going to have to meet you at alum creek this Sunday just so I can show you how easily I fly out of my target zone.) ;)

I've got the Polar F11 too and I absolute love it.

Jen - good point you do get caught up in the calories sometimes. And I do think there are times to work out of that target zone in order to increase your fitness level and teach your body to tolerate lactic acid.

When I first got my HRM, I had to stop jogging and just walk to stay in my zone. BUT...as I got more and more fit, I had to work harder to get up into my zone and so slowly I began jogging and increasing my speed until I am now able to go out and run 3-5 miles or bike 15-20 and still stay in my zone. Takes time though. You have to work in that zone for a while in order to condition your body and as you said, we all feel like we haven't even worked out so most of us don't take the time to really "train" in the zone over a period of time.

And as far as target zones, they really are individual. My zone (I had a VO2 max test done) is 151-171. My husband's is more in line with yours. If his got as high as mine does, he would explode!

Let me know about Sunday. If not this weekend, another. I go out almost every weekend.

Jen - Target rates are different for everyone. Mine is 151-171 but part of that is genetics. I had a VO2 test done. The key is forcing yourself to train in your zone over a period of time so that you force your body to get more fit. You then have to work harder, over time, to get up into the zone. We can talk more in person about this anytime you want.

I also agree that sometimes you want to work out of your zone to force your body to learn to tolerate lactid acid or the threshold for it.

Let me know about Sunday. It not this weekend, another. I am there almost every weekend.

I've only got 20 min a day to work out and have to do as much as I can. I can't worry about a target zone and then only burn 30 calories or something.
