Don't Overtrain

People are incredulous when I tell them I do only two workouts a week, a whole-body weight session and a very hard aerobics session lasting about 30 minutes. (I also walk for an hour or so on four other days, to burn extra calories and speed recovery.) Even my brother-in-law, who runs long distance to control his weight, asked, "Why so little?" My lifelong friend Carl Miller, a former U.S. Olympic Weightlifting Team coach and an excellent lifter in his own right, said, "Frankly, I didn't believe you."
Well, it's true. I've been doing weights on Sunday (two hours or less) and aerobics on Thursday for about a year now. I'm not claiming that twice a week is best for everyone - there is probably no one best training schedule, certainly not for everyone - but it has worked wonderfully well for me.
I believe most people, especially bodybuilders, err on the side of overtraining.

As I confessed in Ripped 2, I overtrained for years. I simply didn't understand the importance of rest. George Sheehan, the famous runner-doctor-philosopher (God rest his soul), perhaps said it best: "The body can be trained for greater performance by induced stress. But the amount of stress and the time allowed for recovery are critical to the success of the process." Like Dr. Sheehan, when it comes to training, I've come to appreciate the wisdom in the saying, "less is more."

As I've explained before, in my books and most recently in the FAQ on this site about Mike Mentzer's new book Heavy Duty II, I've been experimenting for years with longer rest periods between workouts. Mentzer's claim that his clients gains soared when he switched them from training every two or three days to every four or five days (Mike says, "Decomposition doesn't even start after a two-week layoff") prompted me to extend my rest periods to 3 days after weight sessions and 2 days after hard aerobics.

I got the idea of different recovery periods after weights and aerobics from Vladimir M. Zatsiorsky, Ph.D., the famed Soviet sports scientist who is now a professor at Penn State. In his book, Science and Practice of Strength Training, (Human Kinetics, 1995) Zatsiorsky points out that "fatigue effects from different types of muscular works are specific." He says that means you might not be sufficiently recovered to repeat a heavy strength workout, but you may be well recovered for a hard aerobics session. I found that's true.

By Thursday, after an intense Sunday lifting session, I'm not ready for another heavy strength workout, but I am ready for a great aerobics workout. And with two more days rest I'm fully recovered to enthusiastically launch into another heavy resistance session.

That's how my Sunday-Thursday training plan came into being. I also discovered that Mentzer is right about no decompensation even after two weeks. My weight sessions are divided into an "A" workout and a "B," with each being repeated every two weeks. For example, I do the power snatch and squat one week and the power clean and deadlift the next.

This worked great. My strength steadily improved even though my bodyweight was dropping. In the eleven months leading up to the photo session, you could count my bad workouts on the fingers of one hand. My training diary is full of comments such as "Great Workout," "Excellent Session," "Almost Perfect!" I'm sticking to my twice a week schedule.
Twice-a-week training definitely works.

One Work Set Only


One-set-only training is controversial, not only among bodybuilders, but in the academic world as well.
"Just one set of each strength exercise, correctly done twice a week, is generally enough to increase strength significantly." commented the editors of Physician and Sportsmedicine (February, 1997).
"Monumental misinformation," Howard G. Knuttgen, Ph.D. of University Park, Pennsylvania, fired back. According to Dr. Knuttgen, the correct prescription for active adults is "2 or 3 sets repetition maximum per session for each muscle group" done "3 to 4 sessions per week." (PSM, May 1997) But that wasn't the end of it.

Dr. Ralph N. Carpinelli, who teaches the neuromuscular aspects of strength training at Adelphi University, took up Dr. Knuttgen's challenge, in Richard Winett's Master Trainer (February 1998). "There is no scientific evidence, nor is there any physiological basis, that would support the superiority of multiple sets," wrote Dr.Carpinelli. As a matter of fact, continued Carpinelli, "Theoretically, as people become stronger and wish to attain maximal increases in strength and hypertrophy, which is not accomplished without optimal recuperation, they may require lower volume and frequency."
Carpinelli, who did an extensive review of the scientific literature on one set versus many, believes "the quantity of exercise is not as important as the quality of exercise." (Master Trainer, Dec. 1997).
I side with Dr. Carpinelli.

First, when you train your whole body in one workout, as I did, you simply can't do very many quality sets; there's not time or energy to do many sets of each exercise. I rarely did more than one set per exercise (after warm-up) in the eleven months before the photos were taken. What's more, as readers of my books know, I have long recommended only one or at most two work sets per exercise.
The best and most complete explanation why I generally do - and recommend - only one work set is in my book Lean For Life (beginning at page 140). But the gist of it is essentially Dr. Carpinelli's point: Quality and quantity are mutually exclusive. It is difficult, perhaps impossible, to maintain quality or intensity and do many sets. You can train hard or you can train long, but you can't do both.
Try this experiment in two separate workouts. (WARNING: Don't do this unless you are in good shape and have no health problems. If you have any doubts at all, consult your doctor.) First take Dr. Knuttgen's advice: warm up and then do 3 sets of squats "repetition maximum." Select a weight you can do about 12 reps and do three sets of as many reps as you can..

Now, about a week later try it my way: warm up well, put the same weight on the bar and do as many reps as you can, one set only. How many reps did you do? How did you feel afterward? Were you sore a few days later?

My guess is you did 2 or 3 more reps than before, even though you went for maximum reps the previous week. I'll also bet you didn't have much enthusiasm for doing another set (I know I rarely do), and that you got stiff and sore.

As I explain in Lean For Life, when you plan to do multiple work sets, consciously or subconsciously, you pace yourself; you hold back on the first set, saving your energy for the sets to follow. On the other hand, do only one set and you can focus totally on that set without thinking about the subsequent sets. You are freed up to make a better effort; you don't have to hold anything in reserve. The result is a more intense and, therefore, a more productive set. Try it and let me know your thoughts.



I do only one very hard set

Hard Intervals

My weekly aerobic workout was a modified version of the Tabata high-intensity-interval protocol discussed in articles 10, 11 and 12 on this site. I used the Schwinn Air-Dyne stationary bike, the Concept II rower or the treadmill.

As readers of "Forget The Fat-Burn Zone" (Web Article #10) will recall, Dr. Tabata's experimental group did 7 or 8 sets of high intensity intervals (20 seconds work with 10 second rest) four days per week. On the 5th day they added 30 minutes at 70% of V02max before doing 4 sets of 20 second intervals. Because I only did the protocol once a week, I included a steady-state segment along with the 20-second intervals.
After a 5-minute warm-up, I did 5 to 10 minutes at a steady pace (fast enough to be hard at the end), followed by about 5 minutes easy to recover, and then about ten 20-second intervals. I always ended with 5 minutes of cooldown.
Dr. Tabata's group did intervals at 170% of V02max, but V02max can only be measured in the laboratory. I simply experimented and found a pace that made the last interval very hard to complete. I also monitored my heart rate with the Polar chest-strap device (See The Lean Advantage 3, Chapter 6). My heart rate was usually over 90% of my measured maximum (190) at the end of the steady-state segment and again on the last 20-second interval. As my condition improved, of course, I increased the pace of the workout. (AGAIN, DON'T TRY THIS WITHOUT CHECKING WITH YOUR DOCTOR.)
Believe it or not, I came to enjoy these short - but challenging - aerobic workouts. It was not only the challenge that I liked , but the fact I only did this workout once a week. I came to each session well rested and enthusiastic. I don't believe that would've been true if I had attempted to do this very demanding protocol more often, especially when training hard with weights.
Like my whole-body weight session, I'm sticking to once-a-week aerobics. It was fun and the photos prove it worked extremely well. My body fat came down steadily, while my strength increased. Isn't that what bodybuilding is all about?
What's more, I did it at 60!
(Check back with us next month for the results of my treadmill test at the Cooper Clinic.)

Why You May Need To Exercise Less

Why You May Need To Exercise Less

Why You May Need To Exercise Less

January 27, 2012 in Stress | 74 comments

Exercise is a major component of a healthy lifestyle, and the benefits of regular physical activity are well established. When adopting a Paleo lifestyle, modifying your fitness routine to include more high intensity exercise can bring great benefits to energy, body composition, and overall fitness.

However, there are many people who take their physique and physical fitness to an extreme level, particularly in the Paleo community. Certain styles of exercise take the participant to a state of physical exhaustion on a regular basis, which may do more harm than good.

While a consistent, high intensity workout routine may provide some benefits for those people looking to lose body fat and increase their strength and fitness, there is a fine line between training hard and overtraining. While running fast and lifting heavy may be major components of an active Paleo lifestyle, engaging in these physically demanding activities too regularly or too intensely can contribute to many different symptoms of overtraining.

Overtraining goes beyond just excessive “chronic cardio” or too many hours spent at the gym. Certain high-intensity exercise routines may push the body’s stress response too far, leading to a cascade of biochemical responses that can cause serious damage to one’s health in both the short and long term.

While short, intense workouts can be great for inducing fat loss, increasing aerobic capacity, and reducing risk for cardiovascular disease, excessively intense exercise can cause a variety of health problems, especially for those dealing with other concurrent stressors such as autoimmune disease, gut dysbiosis, or adrenal fatigue.

Overtraining has been shown to affect blood levels of important neurotransmitters such as glutamine, dopamine and 5-HTP, which can lead to feelings of depression and chronic fatigue. The stress caused by intense, excessive exercise can negatively affect the hypothalamic-pituitary axis, possibly causing conditions such as hypothyroidism. Hypothyroidism is known to cause depression, weight gain, and digestive disfunction along with a variety of other symptoms. As we know, high stress in general can cause symptoms of hypothyroidism, and the stress caused by excessive, intense exercise is no exception.

Another major effect that extreme exercise has on our bodies is an immediate increase in cortisol, the hormone that is released when the body is under stress. Heavy-resistance exercises are found to stimulate markedly acute cortisol responses, similar to those responses found in marathon running. Chronically high levels of cortisol can increase your risk for a variety of health issues, such as sleep disturbances, digestive issues, depression, weight gain, and memory impairment. Excess cortisol also encourages fat gain, particularly around the abdomen.

When a goal of exercise is to lose weight or improve energy, overtraining can clearly be a major barrier to achieving those goals.

Overtraining can also have harmful effects on the immune system. Research has shown that the cellular damage that occurs during overtraining can lead to nonspecific, general activation of the immune system, including changes in natural killer cell activity and the increased activation of peripheral blood lymphocytes. This hyperactivity of the immune system following intense overtraining can possibly even contribute to the development of autoimmune conditions.

This type of nonspecific immune response is associated with symptoms such as chronic fatigue, weight loss, decreased appetite, and sleep changes. Altered immune status is also known to affect the hypothalamic-pituitary axis, and may be responsible for the hypothalamic-pituitary dysfunction and hypothyroidism known to occur in overtrained athletes.

Mark Sisson talks about the different signs of overtraining, which may be more common in endurance training but is nonetheless possible in high intensity training as well. Feeling ill or rundown, losing muscle mass, gaining fat, and constant exhaustion can all be signs of excessive exercise of any type. Not only is this counterproductive to most people’s fitness and health goals, but it is also a sign of sickness. In the path to better health, any activity that makes you more fatigued and more prone to infection is definitely something to be avoided.

So does this mean you should quit CrossFit, or stop pushing towards your weightlifting goals? Not necessarily.

Here are a few techniques to avoid overtraining while still enjoying high intensity exercise:

  1. Reduce the frequency. While pushing yourself hard at the gym is not inherently problematic, doing it too often during the week is overtraining. High intensity, high stress exercise should be limited to two or three times a week, especially for those who are dealing with other health issues such as autoimmune conditions or digestive troubles. Compounding those stressors with extra stress from your exercise routine will not leave you healthier, and can easily cause you to become more sick.
  2. Get adequate rest. I’ve written before about how important sleep quality is for health. Not only is taking breaks from exercise important, but getting adequate sleep to allow recovery from intense exercise is vital to avoiding the overtraining syndrome. Make sure you are getting adequate sleep, particularly on the days you train. Interestingly, one symptom of overtraining is disturbance of sleep, so if you’re feeling restless and having trouble sleeping through the night, you may want to reconsider the intensity of your training schedule.
  3. Mix it up. While high intensity exercise may be ideal for losing body fat and improving lean muscle mass, we know that high levels of cortisol can cause the body to hold onto fat. For this reason, you may consider trying a type of exercise that can help modulate your cortisol levels. Some may knock yoga as being too easy to affect weight loss, but regular yoga practice is shown to reduce cortisol levels, which may help in reaching your weight and fitness goals. Instead of doing a fourth day of CrossFit, try doing a yoga class instead. You may find that this stress reducing exercise helps you recover more quickly from your more intense exercise schedule.
  4. Eat more carbohydrates. While cutting down carbohydrate consumption is often seen as the best way to decrease body fat, a combination of overtraining and low-carb eating can actually raise cortisol significantly and negatively impact immune function. There is also a possibility that very low carbohydrate (VLC) diets suppress thyroid function, a debate thoroughly discussed by Paul Jaminet on his blog. So if you’re regularly doing high intensity training and want to avoid symptoms of overtraining stress, don’t skimp on the carbs!

High intensity exercise can be a great way to improve body composition and enhance your general health, if done the right way. As with all components of our lifestyle changes, the key is moderation and listening to your body. If you choose to participate in these high intensity training programs, always use your best judgment and don’t let coaches or fellow athletes push you past your comfort zone.

Now, I’d like to hear your experiences with different exercise programs – did your health improve or suffer after increasing the intensity of your training? Have you been able to find a balance between intensity and adequate recovery?
