READ: Marty Gallagher's article


This comes to us from Nate S. He has been meeting up with us for our stair/kettlebell workouts at Swallow Cliff Woods here in Illinios. Nate is big into KBs, SBs, and a whole lot of other odd-object lifting.

Men: Want to Expand Your Lifespan by 10 to 15 years? by Marty Gallagher

The article talks a lot about INTENSITY. And it talks about it in measurable and quantifiable ways.

There is more from Marty on his website at http://www.martygallagher.com/

Heart Rates, Part 2

In Part One I asked each of you to calculate some basic figures. If you look at a typical fitness club heart zone chart, it is an extreme estimate. It does not take into account your resting heart rate, but rather uses an average based on age. Obviously the more precise the raw data used, the more accurately YOUR heart rate zones can be calculated.


These zones reflect exercise intensity. In a Recovery or Warmup Zone, the HR is generally under 50%. If you go back to Part One and recall the 30YOA male who had the HR-Rest = 50, his 50% intensity value is 120 BPM. During an easy warmup session, his HR should stay under 120 BPM.


The next higher intensity zone ranges from 50-60%. I personally detest the naming of a "fat burning" zone as it gives the false impression that a fatter person should stay under 60% intensity. I prefer to call it a low to moderate zone. Training partners can usually maintain a fluid conversation while operating in a 50-60% zone.


Aerobic fitness zones range from 60% to 80% intensity. This is where most endurance runners tend to operate. As intensity climbs towards 70%, speaking ability drops...breathing rate is too high to keep a conversation.

The highest zone is over 80%. This is for extreme athletes who are hell-bent on performance. When training in an 80% range, conversation is next to impossible. As the need for oxygen rises, breathing (and pending recovery) becomes the main focus of the athlete.

Here are some talking points:

As intensity goes up, duration goes down. Simple enough, right? The same person running 3 miles will maintain a lower HR than when s/he runs a 400M sprint, and probably a higher HR than when running 6 miles. The shorter the duration of the event, the higher the intensity of the activity.


Performance is bettered in higher zones. In a few posts ago I discussed my errors when training for stair climbing races. My biggest error was that I had not been spending time in the 80% and up heart rate zone. What I was asking my body to do was to get better at performing a task (climbing stairs) faster and faster, yet I didn't actually increase my speed/intensity. Rather I incorrectly added time duration to the training sessions. In future years when I reached into the 80% zone, I saw big changes in performance.


Interval training. Interval training, especially running, has big benefits. These sessions alternate between high intensity sprints and lower intensity jogs or even walks. As I discusssed in the above paragraph, higher zones need to be reached. Also the long durations cannot possibly be kept as well. In these runs, "resting" periods must be factored in. One popular method to account for balanced intervals is by using telephone poles along a roadway. A runner will sprint between 3 poles, then jog between 5 poles. I also like using my GymBoss timer. I've been using a 5 minute repeating timer to alternate running-walking for a couple of first time 1/2 marathon competitors. Down the road, we'll be decreasing rest periods to 3 then 2 minutes, and eventually to NO rest periods...only running. Interval training definately keeps the boredom to a minimum!!! There are so many ways to spice it up.


Cardio Machines. In my workplace gym I have access to some of the most top-notch pieces of cardio machines: rower, treadmills, versa-climber, stairmaster, elipticals, bikes...you name it. Some of them have the smart handles that monitor heart rate. Most have the option to interface directly with my Polar chest strap. I use these bike and eliptical machines almost exclusively for warmups and cool down sessions. I find it nearly impossible to get my HR into a zone higher than 60% with them. Now the versa-climber (picture to left): I can almost get up to 80%! It's one of the most grueling machines out there.

Beginner workout zones. For those of you just starting off a fitness program, I highly recommend using a HR monitor. It is important to ease into any new program...and by "ease" I mean limiting your HR during training sessions. Do not jump right into a 70-80% zone!! But on the flip side: if you've been exercising for years and you stay in the 60-70% zone, then it's probably time to add intervals and higher intensity workouts to your fitness model.


It might take a little bit to learn your body's limits when it comes to intensity and duration and interval work. It is worth the money to invest in a HR monitor and definately worth the effort in figuring out the math of how your body responds to work. Start today by simply taking your pulse rate before, during, and after your sessions.

The Skinny on Heart Rates, Part 1

A coulple of years ago, at about the same time I began to study and learn about training intensity, I bought a heart rate monitor. I bought a Polar brand, model F11. The particular model consisted of a wrist watch and a chest strap. It works with a transmitter resting on your chest sending a signal to the wrist watch. The resulting readout is how many times your heart is beating per minute....simple enough.

Monitors like these are an easy, comfortable way to get real-time information about your heart's performance during a workout. The old standard of finding your pulse and counting the beats while you watch a second hand on a clock is not nearly as accurate (as your body begins to rest during the exam period, your heart rate falls giving an inaccurate reading...not to mention temporary loss of workout time and intensity).

Here are some watered-down basics of heart rate study:

HR-Max = 220 minus your age OR 205.8 minus (0.685 times your age). Either is an estimate for a number that should be determined by a professional stress test. And because I too love doctors (NOT!), I use 200 minus age ;)

HR-Resting = your heart rate while resting...duh! I usually take mine before I get out of bed in the morning, and definately before I take the morning cup of joe. The average value for an adult is about 70 to 90 beats per minute (BPM).

HR Reserve = (abbreviated HRR) the number of beats between your HR-Max and HR-Resting. Just subtract the two values.

HR-Target = (abbreviated THR) or a value of BPM that matches up with an intensity level of a particular workload. This is math formula with variables from 1-100, 1=resting and 100=max.

Various intensity levels based on heart rate are important to know. After you know the values, use them as target heart rates. Using a THR model gives a more efficient workout with less time wasted to reach set goals. Now let's use a case study to determine some intensity levels.

Subject is a 30yoa male with a HR-Resting of 50BPM. His HR-Max is 190 (=220-30). His HRR is 140 beats (=190-50). Now a 50% intensity workout means his heart is beating at 1/2 its ability (or using half of the 140 reserve or "extra beats"). Take 140 and multiply by 0.5 to get 70. Then add this to the HR-Resting to get a 50% intensity value of 120BPM. To find an 85% intensity value, multiply 0.85 and 140 to get 119, plus 50, equals 169BPM. Now since reaching and maintaining a THR exactly on the number is virtually impossible, THR Zone are commonly used. For example, 50-60% zone or a 75-85% zone.

This is enough math for now. Figure out your values for HR-Max, HR-Rest, HRR, and THR for 50, 60, 70, and 80% intensities. We'll get back to these numbers in Part 2.
