Rest Between Sets




We have selected the routine, that select pattern of sets and repetitions that is going to drive us smashing through the wall. We are going to shred the edge of the envelope and become a new beast. A beast the likes of which has never been seen before. Tight sinews, bulging muscles, veins as thick as garden hoses. People will look on in awe as this chiseled, rock-like God walks the streets with them.
One factor in your routine remains unaccounted. How long to rest between sets? Why does it matter? Alright, two questions remain unanswered. Does it matter?
How long to rest between sets? Why does it matter? Alright, two questions remain unanswered. Does it matter? THREE! Three questions left unanswered!
How long to rest between sets? Why does it matter? Alright, two questions remain unanswered. Does it matter? Before this looks like a Monty Python sketch, there are three questions that will be addressed here. How long to rest between sets, that it does matter, and why it matters. No matter what you are doing rest and recovery does matter.

We can break this down to the very basics of short, medium, and long rest periods. Back when I started powerlifting, stories circulated of “old time” lifters who would squat all day. Their workouts would last 6 to 8 hours. The breaks they took between sets were in the range of 30 to 45 minutes. During which time it was alleged that these elite lifters also drank a quart to a gallon of milk.
These stories remain just those, stories. Although, on some of my freer days, I have been known to take a protein shake to the gym and squat or deadlift for 30 minutes to an hour. But that kind of regular routine is ridiculous. That time does not exist in the schedule.
What we can do is consider the long break at 3 to 5 minutes between sets. This longer period has been found in several scientific studies and anecdotally to have superior results in several areas that weight lifters consider highly important. This allows for higher time under tension through a greater overall number of repetitions per set. This results in deeper muscle density, more gains in strength, and greater gains in size. Along with these studies found overall increases of power. The key pattern found in this is 3-5 sets of 4-6 repetitions per set.

The short range is measured at 30 to 1 minute. Some studies and lifters will carry this out to 90 seconds, but for this piece we will limit the short range to 1 minute. This is more for endurance trainees and is often found coupled with higher repetitions. Reps in the range of 15 to 20 are what I mean by higher reps.
The energy source for this range is oxygen burning carbohydrates and fat. This is aerobic. This type of lifting will burn more bodyfat while exercising. Your body will become more adept at processing and removing lactic acid. The benefit for doing aerobic lifting is that by building muscle strength and density your resting metabolism will be much higher. This is just how it works by increasing lean muscle mass. The higher resting metabolism will burn far more calories in between workouts than you burned during your workout. It is worth doing.
High repetition lifters are looking primarily for endurance and long performance. One often understated technique combination that can be used with the weights at this level is speed reps and pause reps. To illustrate these two let’s consider the bench press.
Once you are settled in with the proper form, you lower the weight to the point that it is just tickling your skin at your diaphragm. Hold the weight at that point for 2 or 3 seconds. This allows you to have total control of the weight and to eliminate the bounce reflex that most lifters rely on to get out of the sticking point of most compound lifts. When you push the bar, do so explosively. Repeat each press with this same technique. The explosive press will fire more muscle fibers than what are needed to move the weight, researchers have found.

The midrange rest period is 1 to 2 minutes. I average that at 90 seconds, mentally that feels right for me, but you go with whichever end of that spectrum you choose.
The number of sets is 3 and the repetition range is 6 to 12. For me, I do 10 repetitions.
This rest range allows the Adenosine Triphosphate Phosphocreatine (ATP-PC) and the glycolic systems to recover enabling another set. According to Oxford Reference (www.oxfordreference.com) the Phosphagen System is described as follows:
The quickest, and most powerful source of energy for muscle movement. The phosphagen system is a form of anaerobic metabolism. It uses creatine phosphate to generate ATP (adenosine triphosphate, the chemical which provides energy for all body processes). Unfortunately, it will support activity for only about 10 seconds, just enough time for top-class runners to complete a 100 metre sprint. Although the phosphagen system produces only a little ATP, it generates energy very quickly. This provides the maximal power needed for short bursts of activity, such as when a sprinter explodes out of the blocks, or when a weight-lifter performs a clean-and-jerk. Creatine phosphate is stored in muscle and its depletion causes fatigue. Dietary supplements which increase creatine phosphate levels in muscles may delay fatigue and improve the explosive power of sprinters and other athletes. See also creatine.
Basically, ATP-PC is a short burst, explosive energy source. It’s used and it’s done. ATP-PC is recovered through the mid and long rests.
History shows that the midrange rest has built bigger lifters. Why? This time range riggers the body to release anabolic growth hormones and responses. Testosterone and Human Growth Hormone are the two primary anabolics in this release. According to Kraemer, et al 1990 and 1991, it is the midrange resting period that triggers the greatest release of the anabolic hormones naturally.
What some may see as a negative, muscle fatigue, is a benefit. The lactic acid building up in the muscle is one of the causes of fatigue. It is also necessary for both strength gains and growth. That is good news per NCBI.

Long rest periods of 3 to 5 minutes let you recover more effectively between sets. This comes out as more repetitions completed in each set. Mathematically, yes math, that is far more time under tension as there are far more repetitions completed. This greater number of reps completed per set allows for more weight increases in a shorter time period. Consider the scenario that 3 sets of 10 reps is when we increase the weight by 10%. The greater rest period allows more recovery. This brings us to more repetitions. Which, as you can see, brings more weight increments sooner.
One technique that works well with this is working alternate muscle groups. Consider doing bench press and bent row, biceps and triceps. I will also combine squats with shoulders and leg isolations. Switching between sexercises allows recovery. Doing one exercise while recovering from another keeps your heart rate up. Another benefit from combining alternating muscle groups is the feeling of the “pump” as the area is filled with blood. I promise you, that pump is awesome. Plus, the extra blood flowing through is bringing in nutrients and bringing out lactic acid and other waste.

Let’s look at some of the benefits in a quick list:
Short – 30-60 seconds
Aerobic Aspect
Increased Resting Metabolism
Remove Lactic Acid
Long, Lean Muscles

Mid – 45 to 120 seconds
Gains in Strength
Gains in Growth/Muscle Size
Increase in Hormone Production

Long – 3 to 5 minutes
Quicker Weight Increases
Faster Strength Gains
Power Increase

There it is, friends, the long and the short, as it were, of taking breaks between sets. This should enable you to better design your lifting regimen to achieve your goals.
Train hard! Train smart!

Concussions and What You Can Do

Concussions
TBI. Traumatic brain injury. Such a nice euphemism for a concussion, isn’t it? That’s what it is, after all. Someone’s brain was violently smashed against the inside of their skull which resulted in deep and, in many cases, permanent damage. One concussion is not all that bad; however, a second soon after the first can be crippling.

Additionally, after the first one, others come easier. The damage compounds upon itself over time even. Watch any interview with career boxers like Larry Holmes. By the end of his career he could barely form a sentence. As a veteran, myself, I can attest to the compounded damage and deterioration. Pay just a little attention to Veterans who have had a few concussions. You will see similar issues shared with professional athletes.
The Center for Disease Control says that between 500,000 and 3 million people in America are treated for concussions each year. Even on the low end, that is a huge amount a damage. Particularly when you consider how much work goes into trying to recover from the damage, to regain the skills lost, regain the physical functions that were basic non-issues just days prior to the injury.
Among the multitude of symptoms that can manifest after head trauma, the primary signs of a concussion to look for include:
·         Headache
·         Nausea/Vomiting
·         Dizziness/Balance Problems
·         Blurred Vision
·         Sensitivity to Light
·         Sensitivity to Noise
·         Numbness in any part of the Body
·         Can't Concentrate/Mental Fog
·         Can't Remember Events just before the injury
·         Can't Remember Events just after the injury

How does one recover from concussions? Does it just take time or is there something that can be done to strengthen the brain tissue itself? The good news is that, yes, there is something that can be done to assist in recovering from the damage. This practice can benefit the brain and body even if you have not had a concussion.

Tai Chi Chuan
Tai Chi translates to The Grand Ultimate. As a philosophy, it has existed for millennia in both India and China. The martial practice of Tai Chi Chuan around 1,000 to 1,500 years ago in China. Tai Chi Chuan means The Grand Ultimate Fist. For more information regarding the history of this art, there are several fantastic articles at YMAA.com, Yang’s Martial Arts Academy.
Practicing this art, as Catherine Kerr of Harvard Medical School (HMS) and many other studies have confirmed, is a unique culmination of physical and mental concentration and coordination. It brings together mindfulness meditation, light to moderate aerobics, and awareness of self and surroundings and one’s relation to them. It is a practice in moving mindfulness meditation.
Harvard scientists confirmed in 2011 that mindfulness meditation thickens the cortical structure in the hippocampus. This is the portion of the brain that governs learning and memory. By thickening the tissue here, essentially improving the function of the hippocampus, patients are able to learn new skills and improve in memory related tasks as opposed to patients with similar injuries who did not participate in tai chi chuan exercises. Due to this, the Veterans Administration has included Mindfulness Meditation exercises as part of its programs for Veterans dealing with traumatic brain injuries (TBI), PTSD, and anger and impulse control among other issues.
Practitioners also show improvements in up to eight regions of the brain (2). Regions associated with motor and executive functions are two important areas to consider. These benefits have been realized by hundreds of veterans through the SHARE Program at the Shephard Center in Atlanta, GA. As a veteran with TBIs, I started practicing tai chi chuan while at the SHARE program several years ago and still practice today. I continue to experience improvements and changes after five years of practice.

How Much Time is Needed?
As mentioned above, changes have been noted in several regions of the brain. This includes the lingual sulcus (LS). The LS encodes visual memories, logical order of events, and speech processing. Practice in amounts as small as 30 minutes per day twice a week have resulted in changes that are easily seen and tracked on a brain scanner.
One area changed is the Anterior Cingulate Cortex (ACC) behind the frontal lobe. This area is associated with self-regulatory processes. These include, but are not limited to, frustration tolerance, behavior inhibition, and self-regulation. Patients participating in studies of 24 weeks in length have shown improved affect in these characteristics (1).
The thickening of the matter in the prefrontal cortex and resultant tests from several studies show that sturdy participants showed improvements in the portions responsible for executive function and attention. Study participants demonstrated increased capacities to recall lists and tasks as well as complete said lists and tasks. There is also a corresponding increase in thickness of the cortical matter of the hippocampus. This part of the limbic system also governs learning and memory. It is also vulnerable to stress-induced injuries such as PTSD. Being able to repair damage to these tissues and regions is extremely hopeful for patients struggling with these issues.
More importantly than seeing these changes on a scanner, these changes are seen in how the practitioners improve in their ability to function in daily life. By thickening the tissue in the frontal cortex and in both the hippocampus and amygdala. These last two are part of the limbic system and are important to us in that they play a major role in memories, decision making, and emotional reactions. 

Conclussion
Both Tai Chi Chuan and mindfulness meditation have shown to increase tissue density in the frontal cortex, as mentioned already. Tai Chi Chuan increases tissue density in the limbic system. This thickening, as with increased tissue and activity in the frontal cortex, results in improved functions. Test subjects show improved memory recall and better emotional control and response to situations.
