Kathy S. RE:exercise
Not just for Kathy S, but for everyone!!! So, just got done watching the View. Whoopi has decided to go on this particular diet/exercise plan and the guy's book is about going Cardio Free. He basically believes that we are wasting our time doing cardio and should just stick with strenght training exercise to essentially build muscle and burn more calories naturally. While I understand that strength training is extremely important (and include it in my exercise routine weekly), why do so many "professionals" want to eliminate something all together. What about balance in our workouts? In our food choices? In our lifestyles? He said that doing cardio will just make us hungrier and cause us to eat more daily. He was using a band to do certain moves, which is great, but what about getting the heart rate up as well?? I guess I just get frustrated with the "all of nothing" mentality. And, what about the person that can't physically do weight training yet, but can get out there and walk!!!! Don't tell them that cardio free is the ONLY way to be! I think its so much more important to find an exercise routine that you enjoy and that you're benefiting from. Of course we all want to use out time wisely and to our advantage, otherwise why do it if we're not gaining anything from it, but why not a combination of cardio and weight/strength training?? Can you tell I didn't buy into everything that he said?!?!?! sorry if this is turning into a small rant, but I get upset when someone says that their way is the only way to get in shape. So, Kathy or anyone that has insight into this please respond~thanks!!!!

So many differing opinions on exercise it can be confusing. It is essential to have a balance between cardio and weight training sort of like Peanut butter and Jelly. I just read an article by Lyle McDonald that weighs both sides of this particular idea. The article articulates quite well the pro's and cons of this type of training. If anyone is interested feel free to contact me and I will forward as I'm not sure of the policy here on posting a publication directly in the forums.
- Depending on the intensity, steady state aerobics tends to burn more calories during the exercise bout than interval training.
- More appropriate for beginners.
- Can be done more frequently, daily or more often (if desired) although this depends on the duration, intensity and frequency as well as the setup of the rest of the training program.
- Some research finds suggests that regular exercise helps people stick to their diet better. In that interval training can't (well, shouldn't) be performed daily, low intensity activity may help people stay on their diets.
- Most indoor aerobics modes tend to be boring, especially for long durations. Exercise can, of course, be done outdoors but this raises a whole separate set of issues (bicycle safety, running outdoors, traffic, etc) that are beyond the scope of this article. This is a big part of why gyms have music and televisions; I have seen one with a cardio movie theater.
- An excess of endurance training, especially at higher intensities (too close to lactate threshold, a topic for another newsletter) seems to cause muscle loss, decrease strength and power, and cause overtraining. This is major issue for bodybuilders and strength/power athletes but can be avoided by keeping the intensity and duration under control.
- Too much repetition of the same mode of aerobics can generate overuse injuries, both runners and cyclists are prone to knee problems, swimming causes rotator cuff issues (and the cold water tends to increase hunger), etc. This can be avoided by non-endurance athletes by rotating the type of activity being done.
- Unless people are tremendously aerobically fit, it can be difficult to burn a huge number of calories unless the duration of each workout is just ridiculous. So, at moderate intensities, the average person might burn 5-10 calories/minute; a 145 lb person burns about 100 calories per mile walking or running. So over an hour aerobic session, you might achieve 300-600 calories burn. While this can certainly add up if done daily, it's still a fairly small expenditure. The people trotting along on the treadmill or spinning on the bike at low intensities, often for only 30 minutes, are burning jack all calories. Which are usually more than compensated when that person figures that they must be burning at least 1000 calories and rationalizes that cheeseburger and milkshake because of it. This is one of those weird ironies: very high caloric expenditures through aerobics are reserved for trained endurance athletes, and they typically don't need it. The people who need to be burning a lot of calories through aerobic activity usually aren't able to, at least not initially.
- For a given time investment, interval training leads to a greater fat loss and this occurs despite a smaller calorie burn during activity. This is because interval training generates a much larger EPOC (excess post-exercise oxygen consumption) which are the calories burned post exercise.
- Interval training may improve the muscle's ability to use fat for fuel more effectively than aerobic training (note: recent studies have also suggested that interval training can generate very rapid improvements in endurance performance in a very short period but this is beyond the scope of this article).
- Time efficient: Not everybody has the time to devote to an hour (or more) of aerobic training per day. A properly set up interval workout may only take 15-20 minutes.
- Time seems to pass faster: Compared to regular aerobics, which can be mind numbingly dull (especially if done indoors), the change in intensity with intervals seems to make the workout pass faster.
- The intensity of intervals makes them inappropriate for beginners. One exception is a style of training called aerobic intervals which I mentioned above. But high intensity interval training is simply inappropriate for beginning exercisers, for the same reason that high intensity weight training is inappropriate.
- Intervals are high intensity training, this has implications for the overall training setup (discussed in more detail in part 2) and integration with the rest of your program (i.e. weight training). Simply put: if you think you can train legs in the weight room 2-3X/week and do intervals an additional 2-3X/week on alternate days, you are incorrect unless you are deliberately trying to overtrain or get injured.
- Higher risk of injuries: this depends somewhat on the type of activity with high impact activities such as sprinting carrying a higher injury risk (especially for heavier individuals) than intervals done on the bike or stair master.
- Limited in how many days they can be performed. Two to three days per week is about the maximum for interval training, most endurance athletes won't do intervals more than twice/week. Have I heard of people trying to interval daily? Yes. Do I think it's a good idea? No.
- Intervals hurt, especially intervals in the 60-90 second range where muscular acid levels are very high. If you're not willing to push yourself, you won't get much out of interval training. You know the warnings on most aerobics machines, that tell you to stop if you feel signs of exhaustion or fatigue; that's what a properly done interval program should feel like. Sensations of burning in your legs (from high acid levels in the muscle) along with extreme discomfort are not only common but expected. Some people also report nausea initially, this can be made worse if they have eaten too close to training.
