Hi,
Back here in Arizona the temperatures are really heating up. Our daily averages are around 105 – 110 degrees Fahrenheit every day. Our monsoon season is starting a little early, which means the chance for daily rain and high winds is increasing. To beat the heat we are making frequent weekend trips up to Prescott, AZ, which is in the mountains. Temperatures up there are usually about 15 degrees lower than in the valley. And, on weekends, they often have very nice arts and craft fairs on the square. We enjoy looking at all the wonderful works of art and the clever things that people do to demonstrate their creativity and talents. Additionally, there are some nice restaurants that we like to frequent when we are up there. We think it's a great place to visit on a summer weekend.
Tomorrow is July 4th. Here in the US it is our Independence Day. We will be spending the day with some friends who live down in Phoenix. They have a pool, and we will be barbecuing while having a nice visit. It should be a great day.
That's about it for now. I guess I'll get started with the rest of the newsletter.
Food for ThoughtI have always known that, at last, I would take this road. But yesterday, I did not know that it would be today. Feature Article - Fat Loss Through Aerobic Exerciseby Thomas D. Manfredi, MS
We exercise for a variety of reasons – weight loss, to build muscle tone, to increase strength, to strengthen our heart, to prepare for a sport, etc. Most of us over the age of 50 exercise to improve our health and fitness. This usually includes most of the things I just listed.
If one of your main goals is to lose weight, you may want to look at the type and amount of aerobic exercise you're doing. Aerobic exercises like walking, jogging, biking, and swimming are most useful for strengthening our heart and can be very effective in helping us to reduce body fat. You should be aware that I didn't say "lose weight" for a very specific reason. We can go on a low calorie diet and lose weight, but it might not help us to be healthier. That's because without proper exercise we may actually lose weight, but not lose unhealthy fat. And, on the flip side, increasing the amount of exercise we do may actually prevent us from losing as much weight. Can this be a good thing? Absolutely. When I started training for triathlons back in the 80's, I lost quite a few inches from various body measurements, but I hardly lost any weight. The reason for this was that the aerobic exercise I was doing helped me burn fat and replaced it with muscle. By volume, muscle weighs more than fat. The types and intensity of aerobic exercises that I was doing to train for triathlons wasn't ideal for fat loss. What I'm going to talk about here is aerobic exercise targeted primarily toward fat loss.
If you have excess body fat that you need to lose to be healthy you basically need to do two things. One, is to make sure that the amount of calories you burn each day exceeds the calories you take in. That requires that the amount and kind of foods that you eat need to be carefully controlled. One of the reasons that I didn't lose more weight and body fat when I was training for triathlons was that I was eating a diet extremely high in carbohydrates in order to give my body enough of the right kind of fuel to do long distance running, swimming, and biking. This is not the ideal diet to help a person lose fat.
The second thing necessary for optimum fat loss is to make sure that you exercise in such a way that as many of the calories that you burn come from stored fat as is possible. Again, my triathlon training wasn't ideal for this because I was trying to train my body to utilize carbohydrates as efficiently as possible and vastly increase my aerobic capacity. I won't go into the physiological reason here, but let me assure you that the diet and exercise routine for a long distance athlete is different from that of someone whose main goal is to lose fat.
So, how do you tailor your aerobic exercise program to help you lose the maximum amount of fat possible? I'm glad you asked. First of all, make sure you're on a relatively low fat diet. This will help make sure that your body doesn't have too many fat calories available from food to burn as fuel. Now, for the most important secret for fat burning using aerobic exercise. You have to make sure that you do your aerobic exercise in the maximum fat burning zone. This is determined by estimating your maximum heart rate (220 minus your age is usually a good estimate). Then determine your fat burning target heart rate (THR) zone by multiplying your maximum heart rate by 55% and 65% to get the range you should keep your heart rate in during your aerobic exercise. Here's an example: I'm 60 years old, so to determine my estimated maximum heart rate I take 220 minus 60, which is 160. I then take the 160 and multiply it by 55% and 65%. This gives me 88 and 104, which is the range I need to keep my heart rate in while doing aerobic exercise in order to maximize my fat loss. Another important thing to realize is that to optimize fat loss, you should do this type of aerobic exercise for 45 – 60 minutes 4 or 5 times a week. You don't have to start with that much, but your goal should be to get up to those times.
To keep your heart rate within your appropriate range you will need to check it frequently by taking your pulse. It's very important that your heart rate stays within your range. If it goes too low you won't get any benefit. And, if it goes too high you'll get benefits, but they won't be the fat burning benefits that you specifically want.
Walking is an excellent form of aerobic exercise to use for maximum fat burning. It's easy to do almost anywhere, and it requires nothing more than a good pair of walking shoes and appropriate clothing for your exercise environment. If you use walking, try to make sure that you're walking in an area that is relatively flat. If there are hills, it becomes very difficult to walk at a consistent pace and keep your heart rate within the desired zone. A treadmill and heart rate monitor can be quite useful in helping you to stay in your zone.
Many excellent forms of aerobic exercise aren't very good for maximum fat loss because they raise your heart rate too high. Things like aerobic dance, jazzercise, stair climbing machines, bicycle spinning classes, etc. are great exercises for strengthening your heart, but they push your heart rate too high for maximum fat loss.
Another nice thing about exercising at a rate that will give you maximum fat loss is that once you lose the fat you'll be in much better shape to use your aerobic exercise for strengthening your heart even more. You will be in a much better position to workout at higher heart rates if you want to.
So, if your main goal right now is to lose unhealthy body fat, you should determine your ideal fat burning heart rate zone and start doing an aerobic exercise that will keep your heart rate in that zone. Teleclasses

The first thing you need to do is determine the target heart rate at which you want to be working. This is referred to as your target heart rate or THR. As a general rule of thumb use a THR of 60% of your maximum heart rate (220 minus your age) for fat loss, 75% for increasing aerobic fitness (improving heart function and strength), and 85%+ to increase your anaerobic fitness (ability to sprint, etc.). Once you have determined your THR, divide the number by 6 or 4. This gives you your THR for a 10 second count (6) or a 15 second count (4). As an example, if you want to exercise at a THR of 120 just divide the 120 by 6 to come up with the 10 second count of 20 or you could divide 120 by 4 which will give you a 15 second count of 30. I prefer to use the 10 second count because it means I don't have to stop my exercising for as long to find out what my THR is.
If you are walking, jogging,or doing any kind of exercise that has you bouncing around, you should slow down or stop so you can accurately count your pulse (same as heart rate). There are two simple ways to count your pulse. With the palm of one of your hands facing you, place the index and middle fingers of your opposite hand lightly on your wrist just above the crease in your wrist on the thumb side of the wrist. You should feel your pulse there. It may take a little practice and slightly moving your fingers around to get the right spot, but once you find it you shouldn't have any trouble finding it again later. The other method is to place the index and middle fingers of your hand on the same side of your neck as the hand you are using. Place the fingers on the neck about an inch and a half below your jaw bone and mid distance between the muscles on the side of your neck and your Adams apple. For either of these methods never use your thumb to try to count your pulse because the thumb has a pulse of its own and it will throw off the count. Once you have found your pulse just watch the sweep hand or digital display on your watch until it gets to an easy spot from which you can count. Your first number for the count should be zero. Stop the count when you reach the appropriate 10 or 15 second period you are using. If the count is within your THR great! If it's too low you can pick up your pace a little. If it's too high, slow down some. When I'm exercising, I check my pulse about 3 to 4 times over the entire time I'm exercising. You can use your own discretion to determine how often you check. When you're new to exercising, or doing a new exercise you should check your THR more often.
