The US surgeon general recommends adults resist the couch potato urge and exercise at least 30 minutes every day. However, many people find it hard to reserve 30 minutes a day for a workout, so the researchers wanted to see if a series of "brisk" 10-minute activity periods would have the same beneficial results as a 30-minute workout.
How was the study conducted?
Their study included sedentary men and women in their mid-40s. The volunteers participated in either a brisk 10-minute walk three times per day, or a brisk walk lasting 30 minutes once per day, 5 days a week for 6 weeks. After a 2-week rest period, the groups switched walking routines and followed the other group's instructions for another 6 weeks.
What were the results?
Both groups saw improvements in heart disease-related factors including a slight drop in total cholesterol and boosts in "good" cholesterol and aerobic ability. Both walking patterns resulted in similar decreases in tension and anxiety.

This is an interesting perspective that contradicts some long-held theories on exercise that suggest that exercise must be continuous for 30-60 minutes to provide major benefits. Common sense would dictate that multiple short bursts of exercise would certainly be better than no exercise, but I suspect future studies will establish if they are equivalent to one longer continuous approach.
When I was lecturing in Dallas recently I met someone at the Symposium who challenged me to reexamine my views on exercise by looking more seriously into SuperSlow weight training. While I've been doing that for the last 18 months or so, I did not realize that I was doing the program improperly as I was using free weights. There appear to be some very compelling arguments to consider this type of approach to exercise. Time would certainly be one of them, as one of their claims is that if done properly you only need one 15-minute workout per week.
I would like to emphasize some key points on exercise that I believe will be enormously helpful in providing some practical guidelines so you can be successful with your program:
Listen to your body. If exercise worsens symptoms, modify your program or stop, if need be. As your energy and health improve, on the program you will tolerate larger amounts of the aerobic exercise and lose weight.
It helps to hire a personal trainer who can guide you through the specifics of a good exercise program. If you do use a a personal trainer please be aware that many don't understand the nutritional principles discussed in this book, so use the book as your nutritional guide.
Stick with it. The fact that we need to exercise is not news to anyone reading this book. However, the big breakthrough is that we now have the new technologies of psychological acupressure techniques like EFT that can facilitate our ability to start and successfully stick with a long-term exercise program. You can go to my free EFT manual to learn how to use this incredible tool.
Be consistent. You will need at least 30 minutes of exercise a day before you will start to experience any weight loss benefits. Large studies have shown that 60 minutes a day would be better. Ideally the exercise should be continuous, but it could be split up into two 30-minute sections.
Start with walking if you are overweight. Most heavy people start with walking and that is an excellent choice, as it is low-risk and inexpensive. The major problem with walking however is many people become fit relatively rapidly and they don't increase the intensity of the workouts as they become more fit.
Increase your intensity regularly. Ideally you should exercise at an intensity that makes it somewhat difficult to talk to the person next to you. This prevents you from having to measure your pulse or use a heart-rate monitor. If you can comfortably talk to the person next to you, you aren't going hard enough to produce the benefits you need to lose weight. If you are using so much oxygen with your exercise that there is not enough left over to allow you to carry on a conversation then you are exercising too hard and you need to cut back a bit.
Try racewalking. It is sometimes difficult to walk fast enough outside to get to this level of exertion. You can try race walking and Racewalk.com has an excellent section on teaching you how to do that. However, if you use a treadmill you can easily increase the incline to improve the intensity of the walking.
Try running. If you feel ambitious you can elevate to running, which is my personal favorite and have been doing sine 1968. I like it because it is one of the most efficient and inexpensive ways to stay healthy. You don't require any equipment except a good pair of shoes. If you do decide to run please recognize that most shoes will not last more than six months. If you use them longer than six months you will increase your risk of injury.
One of the downsides of running is that you will need cooperation with the weather. You can always use a treadmill, but that would mean the increased expense of a health club or equipment for your home. If you are elevating your program to that level I believe that the elliptical is far superior to the treadmill in providing an optimal aerobic exercise experience.
Try an elliptical machine. Elliptical machines are generally less expensive and far quieter than treadmills and provide a complete lower body workout by rotating the use of the different muscle groups on your legs. However, you will have to be sure to use the elliptical that can incline throughout various levels. Some models have a fixed based and handles that allow you to exercise your arms, but I believe it is more helpful to exercise the different leg muscles as they are much larger than your arm muscles. The model I use is the Precor 546.
The Precor 546 is a commercial piece of equipment that will last you a lifetime as it is designed to stand up to the rigors of a busy health club. I travel all over the world and when I go into a fitness center that doesnt have the Precor brand elliptical I am saddened because I have never found an elliptical machine that was better than the Precor 546.
The 546 model does not have the levers so you can use your arms. This is a good thing as the most powerful muscles in your body are in your legs. Unlike the models that allow you to use your arms, the 546 gives you a wide range of incline choices that allow you to fully workout all the different muscles in your legs. The model with the arms has a fixed base and will not allow as complete a workout of your legs. You can save your arm workouts for resistance weight training and I believe you will have a far better more comprehensive training effect.
It is my impression that the Precor 546 is the single best piece of fitness equipment available anywhere in the world today. That is why I have owned a Precor machine for a number of years. This model features a unique ramp that changes the stride motion and allows you to train the different muscle groups. I normally suggest adjusting the resistance setting and frequency of steps per minute so one is just short of not having enough breath to carry on a conversation. This is the aerobic threshold that will produce cardiovascular benefits.
You may think the price of the machine is a bit high but when you compare it to a treadmill is it right in the ballpark and in my estimation is a far better exercise for you. It has about 90% less noise than most treadmills so you can easily watch TV or watch videos while you workout (my favorite). This is close to impossible with many treadmills.
Also the convenience of having one of these in your home is difficult to put a price on. But if you even value your time at $10 per hour and you wind up saving two hours of travel time per week by not having to go to your health club, you will cover the cost of the machine in a few years. Many of you reading this may earn far more than $10 an hour and save more than two hours per week in commuting time so your payback time will be well under one year.
It is also difficult to place a value on how good you feel and all the diseases that you will prevent by owning one of these machines as, in my opinion, there simply isnt a better piece of equipment to purchase to get you in good shape. How can you put a price on preventing a heart attack or fatal cancer? You may not realize it, but exercise has been clearly shown to reduce cancer rates. It probably does this by lowering insulin levels.
So not only will you reduce cancer and heart attacks but you will also reduce nearly every single chronic degenerative disease. So do yourself a favor and try out a Precor 546, if you like it as much as I think you will reward yourself by getting one for you and your family so you can enjoy all the benefits of finally being in shape.
Be cautious. If you are going to use exercise for weight loss you will want to consider a weight bearing exercise. It has been my experience that non-weight bearing exercises like swimming and bicycling are not as efficient or effective for weight loss. You will typically need to exercise four times as long in these activities to receive the same benefit of running or using the elliptical. Since most of us are seriously time pressured, these exercises become less valuable for most of us.
Swim, but only in fresh water. Swimming has the additional challenge of exposing you to large amounts of chlorine that are in most swimming pools. However you still have the option of swimming in the lake, river or ocean depending on the temperature of the water.
Try bicycling, but be aware of safety measures. If you decide to use bicycling you will need to be concerned about the risk of injury. You don't have to be wrong to be seriously hurt on a bike so please be sure and always wear your helmet.
