In recent years, great advances have been made in the way athletes warm up – particularly in the realms of weightlifting, powerlifting, and CrossFit. Between websites like Kelly Starrett’s Mobility WOD, the work done by Ryan Brown and Dr.Quinn Henoch here at Juggernaut, and other like minded organizations and resources, we are a far cry from the oft ignored warm-ups of yesteryear (or at least 2005.)

But in the pursuit of improved tissue quality, better joint articulation, and more effective breathing patterns, it seems to me that other important components of the daily warm-up have been put aside.

Along with preparing the body for exercise by raising the core temperature, improving range of motion, and priming specific movement patterns, a well planned warm-up should also serve as an opportunity for the competitive CrossFit athlete to improve their volume tolerance and practice skills.

There are surely a myriad of ways to achieve this goal. Below, I have outlined the simple process by which my athletes design their daily warm-ups.

1) EXERCISE SELECTION

We use five different movement types in the warm-up. Monostructural/Aerobic, pulling, pressing, squatting, and midline. A few examples of each below:

AEROBIC: Run, Row, Airdyne, Jump Rope

PULLING: Pullups, Strict Pullups, Chest-to-Bar Pullups, Muscle-Ups*

PRESSING: Handstand pushups, Strict HSPU, deficit HSPU, Muscle-Ups*, Ring Dips

SQUATTING: Squat, one legged squat, wall ball, walking lunge, jerk grip overhead squat

MIDLINE: Plank, Hollow Rock, Toes-To-Bar, Knees-To-Elbows

Outside of these categories, exercises typically fall into one of four types.

DEVELOPMENTAL: Planks, strict pullups, and jerk grip overhead squats are examples of developmental exercises. They are not very likely to be seen in competition, but they help the athlete improve fundamental qualities which carry over to the rest of their training.

COMPETITION: Wall ball, Toes-to-Bar, double unders. Highly competition specific exercises, they provide relatively little carryover to other movements, but allow the athlete to practice pace, technique, and timing.

HYBRID: Muscle-Ups, handstand pushups, one legged squats. These movements are important to practice for their own sake, as they are integral parts of competition, but performed correctly can also carry over to other exercises.

ACCUMULATION: Pushups. Sit-ups. Bodyweight lunges. These are movements which, beyond the novice stages, are not likely to have a lot of carryover to other things you do, and are not very likely to show up in competition, but afford the athlete an opportunity for a low stress warm-up which still accumulates reps.

2) VOLUME

Once you’ve selected your exercises, the next question is “how much?”

The short answer is “enough to practice, but not enough to make you tired.”

On bodyweight exercises, a safe bet is to do 20% of your best for three sets (so if your max is fifty kipping pullups, you’d do three sets of ten.)

For exercises like wall ball, do sets that you are working towards being able to hold in a workout. If under fatigue you break down to sets of 7-8, hold sets of 10 during your warm-up.

Gradually increase the volume of each exercise over the course of weeks and months.

3) VARIANCE

As with most things we do in CrossFit, the warm-up should be varied. A simple solution, assuming five training days, is as follows: In each movement category, have two days of hybrid exercises, one day of developmental exercises, one day of competition exercises, and one day of accumulation exercises.

In practice, a five day warm-up schedule may look like this.

Day 1: Row 1000m @ 90% of 2k pace, then three rounds of: 10 butterfly pullups/10 strict ring dips/16 one legged squats, alternating, 10 knees-to-elbows

Day 2: Three rounds of: 50 double unders, 10 supine ring rows, 15 pushups, 20 walking lunges, 20 situps

Day 3: Every minute for 10 minutes, perform 20 double unders. Then three rounds of: 5 muscle-ups, 10 handstand pushups, 10 jerk grip overhead squats, 60 second front plank

Day 4: Three rounds of: Run 400m, 6 strict chest-to-bar pullups, 6 strict, maximum depth ring dips, 12 wall ball shots, 10 strict toes-to-bar

Day 5: 5 minutes on Airdyne @ 70%, then three rounds of: 8 kipping chest-to-bar pullups, 8 strict handstand pushups, 12 Goblet squats, 10 toes-to-bar

Over time, add a rep here, a rep there. Challenge yourself by including novel and more complex movements, particularly from the gymnastics realm. Eventually you will find yourself doing more work more quickly and recovering from it with ease.

In Part III, we’ll learn our ABCs.

picture of paleo person jumpingThere’s no question that regular exercise is essential to health. Our paleolithic ancestors had a different word for exercise: life. For the vast majority of our evolutionary history, humans had to exert ourselves – often quite strenuously – to get food. We naturally spent a lot of time outdoors in the sun, walking, hunting, gathering, and performing various other physically-oriented tasks. We had no concept of this as “exercise” or “working out”. It was just life.

Things are different today. 60% of American adults are not regularly active, and 25% are complete couch potatoes – they get no exercise at all, other than walking back and forth between the car, the cubicle and the refrigerator. This lack of physical activity has profound consequences. Regular movement protects us from disease in several ways, but most importantly it prevents oxidative damage and inflammation – the primary mechanisms underlying most modern, degenerative diseases. This explains why those who are completely sedentary have between 1.5 and 2.5 times the risk of developing heart disease and a higher risk for virtually all modern, degenerative disease.

On the other hand, we’ve got the exercise fanatics. Many Americans have been caught up in the fitness craze over the last 40 years, devoting countless hours to jogging, the Stairmaster or the treadmill in the hopes of slimming down, getting healthy and preventing disease. But while this type of activity may help with stress management, research suggests that it’s useless for weight loss and may in fact be detrimental to health.

If you doubt this, you’ll have to explain why Americans have continually gained weight over the last 40 years, in spite of increased leisure time exercise and increased energy expenditure.

Why “cardio” doesn’t work for weight loss

When I say “cardio”, I’m referring to steady-state, repetitive activity done at a moderate intensity like jogging outdoors, running on a treadmill or climbing the Stairmaster. [Side note: the idea that you have to perform this type of activity to benefit your heart and vascular system is false. Anything that places a demand on the muscles – including so-called anaerobic activities like weightlifting – will also condition the heart and vascular system.]

Most people are surprised to learn that cardio doesn’t work for weight loss. How could this be? There are three main reasons:

  • caloric burn during exercise is generally small;
  • people who exercise more also tend to eat more (which negates the weight regulating effect of exercise); and,
  • increasing specific periods of exercise may cause people to become more sedentary otherwise.

In an example of the first reason, a study following women over a one-year period found that in order to lose one kilogram (2.2 pounds) of fat, they had to exercise for an average of 77 hours. That’s a lot of time on the treadmill just to lose 2 pounds!

In an example of the second reason, a study found that people who exercise tend to eat more afterwards, and that they tend to crave high-calorie foods. The title of this study says it all: “Acute compensatory eating following exercise is associated with implicit hedonic wanting for food.” I love it when researchers have a sense of humor.

In an example of the third reason, one study assigned 34 overweight and obese women to an exercise program for 8 weeks. Fat loss at the end of the study was an average of 0.0kg. Not very impressive. But the researchers noticed that some women did lose weight, while others actually gained. What was the difference? In the women that didn’t lose weight, the increase in specific periods of exercise corresponded with a decrease in overall energy expenditure. Translation: they were more likely to be couch potatoes when they weren’t exercising, which negated the calorie-burning effect of their workouts.

If you’re still not convinced, the Cochrane group did a review of 43 individual studies on exercise for weight loss. Study length ranged from 3 to 12 months, and exercise sessions lasted on average 45 minutes with a frequency of 3-5 times per week. The results? On average, the additional weight loss from exercise averaged about 1 kg (2.2 pounds). Meh. Assuming they worked out for 45 minutes 4x/wk over 6 months, that means they had to exercise 69 hours to lose that 1 kg.

Why cardio may be harmful

Too much cardio exercise has a number of harmful effects on the body:

  • increases oxidative damage
  • increases inflammation (the root of all disease)
  • depresses the immune system
  • decreases fat metabolism
  • disrupts cortisol levels
  • causes neurodegeneration

Overtraining is especially damaging because of its effects on cortisol. We discussed cortisol at length in Step 6: Manage Your Stress, but in this context what’s important to understand is that too much exercise can disrupt our natural cortisol rhythm and drive levels too high initially, and depress them over time. Cortisol dysregulation promotes abdominal fat gain and muscle loss, which in turn causes further weight gain.

There’s also some evidence that frequent endurance exercise may promote – rather than prevent – heart disease. Dr. Kurt Harris summarized a study performed on 102 active marathon runners and 102 age-matched controls to determine the effect of aerobic exercise on cardiovascular health.

The marathoners were between 50 and 72 years of age, and they ran an average of 35 miles per week. They had no known history of heart disease or diabetes. The control group was similarly aged and also had no history of cardiovascular or metabolic disease.

You might be surprised to learn that the marathon runners were three times more likely to have heart damage than the non-runners. Among the runners, there were 12 heart attacks vs. 4 attacks in the non-runners.

In another study by the same authors, the more marathoners ran, the higher their likelihood of heart disease. In fact, the number of marathons ran was an independent predictor of the likelihood of irreversible damage to the heart tissue.

No cardio? Then what should we do instead?

In short, we should move like our ancestors. They didn’t strap on a heart monitor and take off for a 45-minute jog, nor did they go down and swim laps for an hour in the local lake. Yet they were extremely fit and almost entirely free of the modern diseases that plague us today.

They performed low-intensity movements like walking, gathering foods or working in other capacities on a regular basis. These periods of low-intensity activity were punctuated by brief periods of much higher-intensity activity – such as going on a hunt, running for a predator or fighting for survival.

This is the type of movement our bodies are adapted for, and thus this is what we should aim for in our daily lives. But how do we do that? As Mark Sisson suggests, we should:

  1. Move frequently at a slow pace
  2. Lift heavy things and sprint occasionally

Move frequently at a slow pace

Moving frequently at a slow pace means approximately 3-5 hours a week of low level activity like walking, cycling, gardening, hiking, performing manual labor, etc. This mimics our ancestral pattern of movement, helps maintain a healthy weight, promotes proper metabolic function and provides a foundation for more strenuous activity. Another benefit of this type of activity is that it’s often performed outdoors. Spending time outdoors reduces stress, increases vitamin D levels, and brings us pleasure, joy and a sense of connection with the world around us.

I think one of the best ways to do this type of movement is to integrate it into your daily life. This could include commuting to work and doing errands on foot or by bicycle, taking the stairs instead of the elevator, doing your own gardening and yard work, etc.

Lift heavy things and sprint occasionally

In contrast to cardio, this type of exercise involves performing movements at very high intensity for short periods of time – usually between 30 seconds and 2 minutes. This is sometimes referred to as high intensity interval training (HIIT).

Several studies have been done comparing HIIT to low-intensity, steady-state (“chronic cardio”, as Mark Sisson calls it) exercise, and HIIT has been shown to be superior in nearly every meaningful marker.

In this study, one group was assigned to “chronic cardio”, while the other was assigned to intervals of 8-second sprints. After 15 weeks, the researchers concluded:

Both exercise groups demonstrated a significant improvement (P less than 0.05) in cardiovascular fitness. However, only the HIIE group had a significant reduction in total body mass (TBM), fat mass (FM), trunk fat and fasting plasma insulin levels.

A pair of studies done at McMaster University found that “6-minutes of pure, hard exercise once a week could be just as effective as an hour of daily moderate activity“, according to the June 6, 2005 CNN article reporting on the study.

The study itself was published in the Journal of Applied Physiology, and it revealed that HIIT resulted in unique changes in skeletal muscle and endurance capacity that were previously believed to require hours of exercise each week.

follow-up study confirmed the results. Despite the fact that the more conventional endurance exercise group spent 97.5 percent more time engaged in exercise, both groups of subjects improved to the same degree. The group that exercised 97.5 percent more received no additional benefit whatsoever from doing so. Considering the wear-and-tear and increased risk of injury associated with that much more exercise, there’s absolutely no point to doing “chronic cardio” when you can receive the same benefits with a fraction of the time and risk by doing HIIT.

The Cochrane study I linked to earlier in the article also found that high-intensity exercise was superior to “chronic cardio”. In particular, the researchers found that high-intensity exercise led to a greater decrease in fasting blood glucose levels than low-intensity exercise.

Why high-intensity exercise is better

bbsIn his excellent book on high-intensity strength training, Body By Science, Dr. Doug McGuff explains that high-intensity training is superior to chronic cardio because it produces a greater stimulus and thus more effectively empties the muscles and liver of glucose. This stimulus can last several days with HIIT, as opposed to just a few hours with low-intensity training.

HIIT also activates hormone-sensitive lipase (HSL), which mobilizes fatty acids for energy use. This means that during HIIT, both glucose and fatty acids will be burned, leading to greater fat loss and restoration of insulin sensitivity.

High-intensity strength training: best of all?

Both high-intensity running or bicycling sprints and high-intensity strength training are effective. But I believe high-intensity strength training is probably a better choice for most, simply because the wear-and-tear and risk of injury is lower – especially if the strength-training is performed using weight machines as described in Body By Science.

This is, in fact, the method of training I’ve been doing since April of last year. I admit I was somewhat skeptical about it all before I read Body By Science. But the research and the physiology was convincing, so I decided to give it a try.

The results have been incredible. My workout varies in length between 5 and 9 minutes a week. That’s right, I said minutes. With only a few exceptions, I’ve increased the amount of weight I can lift, the time I can lift it, or both, with each successive workout. My strength has increased and my physique is, if anything, better than it was when I was lifting 3x/week for much longer periods.

Where to learn more about HIIT

There are many books on the subject, but these are the two I’d recommend for most people:

  • Body By Science, by Doug McGuff. The “bible” on high-intensity strength training. Goes into great detail on the physiological mechanisms and benefits behind this type of exercise, and explains how to put together a routine. Doug also has a great blog with an active community of people using the BBS approach. To see an example of what this type of workout looks like, check out this video on YouTube. For an in-depth video presentation about BBS, watch this video.
  • The Power of 10: The Once-A-Week Slow Motion Fitness Revolution, by Adam Zickerman & Bill Schilley. This is more of a nuts-and-bolts book, with less theory than BBS and more focus on teaching you how to do this type of workout. It also has specific routines that can be performed at home, on the road and without access to a gym. The approach is slightly different than what’s advocated in BBS, but the basic idea is the same.

My training system that works for me the best

 Let me start in the beginning. When I started crossfit couple of months ago I was training almost everyday. I was (I am) more like a cardio guy than a powerlifter. These days I am still a cardio guy and doing crossfit girls, heroes and other metabolic conditioning stuff like hell but I am much stronger. Basically my training looked like this. A month (1 cycle) contained 4 weeks – light, medium, heavy, deload and trained like this:

 

Weeks are different by sets, reps for example on week first 5×5, medium week 5×3, heavy week is up to me. Normally I check my 1RM but until I reach it I do several sets and reps based on autoregulation. Easier….how I feel it.

 I had been doing this method for two months but it did not show results that I wanted to reach.

 Here comes the 5-3-1 method.

It was pain in the ass. Really, especially week one and week two with their 3×5 and 3×3 on a certain percentage of 1RM.

Good thing is my strength increased a lot. My deadlift went up from 102,5 kg to 132, kg.

 BUT

I realized I was soooo tired during every heavy week because my CNS (central nervous system) was burned out on the first day. This inspired me to read more about CNS fatigue.  More about this.

The conclusion is the following: If you burn out your CNS on day one on your heavy week you will not be able to do another REAL 1RM on next training day. CNS gives information to your body, to your muscles such as “Stop, no more real maximum load this time”. It “blocks” your performance to protect the body from injuries.

 HERE IS MY SOLUTION THAT WORKS FOR ME

Intensity and load rotation within a week through a 4-week cycle (click on the pic to see more) mixed with the 5-3-1 method assistance exercises (not in the list below).

As you can see you do only one 1RM every week. I experienced that I was able to continue my training with acceptable performance on the other days (L,M,D). It was said the CNS “blocks” your body for another real 1 maximum repetition that is why I can do my best the rest of the week on the appropriate level. So, I burn out CNS once a week, not twice or more. It needs less regeneration period.

You should listen to your body because a huge mistake was made. What? I did not listen to the signs. In general I take a week off after every 3rd cycle but once I felt I can do another a 4th cycle but I burned out during the second week and on 3rd and last week I suffered from several injuries, mainly shoulder. So do not train continously all year without proper resting or regeneration periods.
