Now that you know a bit about your cardiovascular system, let’s get started on understand your heart by taking some baseline measurements. Your Resting Heart Rate (RHR) is the slowest heart rate for you and gives valuable information regarding your current fitness level.
Take your resting heart rate when you first wake in the morning but are still lying in bed. Find your radial (wrist) pulse with your first and second fingers of the opposite hand and count the number of beats you feel over 60 seconds (one minute). If you have a Heart Rate Monitor with Touch Screen, just reach over to your bedside table when you wake up, strap it to your wrist, and take an instant reading. Do not move around much as your heart rate can instantly jump 10-20 beats just reaching across your body; lay still for a few minutes when the monitor is in place.
Resting heart rate varies from 50-90 beats per minute across the adult population. Athletes are known to have resting heart rates as low as 30-50 beats per minute. I recommend you take your resting heart rate at least three times a week in the morning as your fitness improves, then at least once a week when you reach your goal resting heart rate and are in a health-maintenance stage.
This link has a RHR chart: What does your RHR say about your fitness level? For example, I am a 31 year old female, 5 ft 5" and 115 pounds. I take 7,000-12,000 steps per day and I exercise about 5 days a week for one hour at a time. My resting heart rate for the past month has been 45-55 beats per minute (bpm). Readers: What is your RHR? Comment below!
Resting heart rate declines over time when fitness improves due to an increase in stroke volume and increase in parasympathetic innervations (Robergs, 2003). After one month of increased endurance training (walking, running, swimming, biking more often) your resting heart rate can decrease by 5-10 beats per minute and stay lowered, showing you have improved your blood volume to supply oxygen to your healthier body, increased your heart muscle strength and capacity, and improved your nervous system. With a regular, appropriate cardiovascular program, your resting heart rate will drop around 5-7 beats a minute each month until you reach your best health and fitness level at around 50-70 beats per minute (Horton, 2011).
Day to day changes in resting heart rate: If your resting heart rate at any time jumps 15-25 beats during the week on a given day, it may be that you are overtired, overstressed, exposed to illness, and/or lacking recovery time. Mine RHR usually reads 60-70 bpm on these mornings. Aim for a gentle workout with walking, yoga, or mind-body meditation on this day and try more cardio when your resting heart rate calms down (Burke, 1998). Combine both long term improvements (decreases) in resting heart rate and day to day changes from stress and recovery, and you’ve got great motivation to track your resting heart rate as I mentioned above.
Heart Rate Variables in this Picture: Just to review, resting heart rate is your slowest/calmest heart rate number. Smaller people have smaller heart sizes, less volume pumped per beat, and therefore faster heart rates. Later we will explore how changes in posture (lying, sitting, and standing) cause instant heart rate changes as do changes in temperature (hot versus cold). NOTE: Check with your doctor before beginning an endurance program if you take medications that affect your heart rate, blood pressure, or metabolic systems.
Readers know I've wanted to share my recent experimentation with Heart Rate Monitors. But first it is important to share some Anatomy (body structure) and Physiology (body function) about our hearts.
Your Cardiovascular System is your heart (cardiac), blood vessels (vascular), and circulating blood. The wellness of these elements allows for oxygen transportation to your working tissues, blood pressure control, fluid balance, and body temperature regulation. Pulmonary refers to the circulation of blood through your lungs; Systemic is the circulation of blood through your body. Arteries (from the heart) and veins (to the heart) are smooth muscle and can change slightly increase or decrease blood flow or redistribute flow through the body.
What is one Cardiac Cycle? The right side of your heart receives blood from your body and sends it to your lungs for oxygen uptake. The left side receives oxygen-rich blood from your lungs and pumps it to your body. The left and right volumes of your heart are the same, but the pressure is highest leaving your heart on the left to the body and lowest where it returns from your lungs on the right.
What is Blood Pressure? 1/3 of your Cardiac Cycle is blood flowing passively into the heart, or Diastole. Systole is the other 2/3 of the cycle: the force of the ventricles (lower chambers of the heart) contracting. When you begin walking and progress to running, Systole slightly increases and Diastole should remain the same or slightly decrease. Both Systole and Diastole can improve (usually showing a decrease) within three months of beginning a regular cardiovascular program.
Did you know? Plasma Volume increases by 10% within 24 hours of an endurance workout which increases return to the heart and load/fill before each heart contraction.
Stroke Volume is the amount a heart can fill and pump per heart beat. This varies by gender (men have larger heart volume than women) and fitness level. During events, the stroke volume of an athlete can be as much as 70% higher than untrained subjects for a similar heart rate.
To help you understand more: An elephant has a huge stroke volume (large heart) and low heart rate. A hummingbird has a tiny stroke volume (tiny heart) and high heart rate. A baby has a lower stroke volume and higher heart rate than an adult; his/her heart rate slows as his/her heart and body grows larger.
With all other variables removed: In adulthood, the maximum number of heart beats per minute decreases on average by about one beat per year.
Cardiac Output is the volume of blood pumped for a given heart rate each minute, both controlled by the nervous system and hormonal changes in the heart in response to the body’s demands. Raise either heart rate or stroke volume and blood circulation increases.
How our bodies are limited: Oxygen Delivery or Oxygen Use?
During exercise above one’s aerobic capacity (where delivery meets demand), skeletal muscle can use oxygen quicker than our circulation can deliver it. This is why some athletes turn to Blood Doping (artificial increase red blood cell numbers through injections) although it is highly dangerous and illegal. The smart athletes can instead train at higher altitudes to increase the demand and production of red blood cells in a healthy and legal manner, the benefits of which occur after only one to two weeks but fade within three days of returning to lower altitudes.
Cardiovascular Drift: As you aerobically exercise anywhere from 10-60 minutes, stroke volume decreases due to increasing demands from temperature regulation, decreasing hydration levels, and increasing muscle metabolism. Heart rate will therefore increase to keep cardiac output constant.
Now you know some basics on what the cardiovascular system is all about, I’ll be sharing posts on:
- The Value of Knowing Your Resting Heart Rate
- The Benefits of Warm Ups and Cool Downs on Heart Rate
- Variables: What Changes our Heart Rate
- How and Why to Use Heart Rate Monitors
- Training Zones and How do you Calculate Yours
- Training Tips and Special Considerations for Endurance Work
AND a page of the resources I’m using to bring you this valuable information.
PHEW! This is why these posts are slow to be published… there is so much to know about how to achieve and maintain your best heart health. But don't you feel smarter already?
One thing all superhero movies have in coming are a hero that doesn’t want the job. Frodo doesn’t want to carry the ring. Spiderman wants to get married and settle down. Luke just can’t find the force.
Heroes everywhere have battles they ignore, run from, or try to side step.
- People are losing jobs and moving away, starting over.
- People are trying to have children and finding they can’t.
- People are going to war to fight for their countries and coming home changed.
- People are trying to find purpose and joy in the things they’ve worked for that, in the end, are not what they thought they would be.
Briefly pause the chaos and look at your life from a different angle.
There are 168 Hours in One Week.
1. Take 5 Hours a Week to Exercise: 20-60 minutes a day and find your power.
2. Eat with Purpose: food entering your mouth should have a goal IN your body.
WARNING: Those against you achieving the two steps above are part of the DARK side!
“I’ve spent much of the last five years trying to help communities improve the effectiveness of their health and wellness efforts. One of the most stubborn challenges is getting kids to move out from behind the TV and computer screens and exercise. It is one thing to tell them to get 60 minutes of exercise each day, but it is far more difficult to make that a reality.
Last summer, I asked my 11-year-old son Alec about how to help make better progress in this important area. His answer was simple: “You have to make fitness fun.” So, I followed on by asking him what was the most fun thing he did that was a lot of exercise. He answered, “Playing ‘ultimate challenge’ in gym class.” I had never heard of that game, so I asked a few more questions. What he shared opened my eyes to what I think it the ideal activity for communities to embrace to promote youth fitness.
Ultimate Challenge is a game that gets kids of all ages and abilities running more than any game I’ve seen. It is like three simultaneous games of “capture the flag” going on at the same time, and regardless of age (from 6 to 60) or physical fitness level, there is always a motivation to run. Either you’re charging in to capture a football, playground ball or rubber ring, or you’re being chased, trying to catch someone, or trying to rescue a friend. The rules are simple, and it is FUN!
That night, we decided that the best way to promote Ultimate Challenge as a popular activity across the country would be to create kits that contain everything that groups or organizations need to play the game or host an event where kids could play the game. The next day we registered www.ultimatechallengekits.com and started a “social entrepreneur” business to help get kids fit.
Roll the clock forward several weeks, and my son got his first order to provide 20 kits to the Get Up & Go! Campaign for St. Clair County, Illinois. A non-profit hospital had purchased 20 kits to give away to youth groups that joined their community fitness initiative. The kits were an incentive for youth groups (like Boy Scouts, church groups or after-school programs) to embrace fitness, and the kits provided them with everything they needed for kids to get a lot of exercise month after month for years to come.
More recently, a non-profit organization in Minnesota wanted to host a field day for kids from an urban charter school. They rented 3 Ultimate Challenge kits for a day and had about 15 volunteers come to supervise (and join in the fun) with nearly 100 grade-school age kids. It took about 15 minutes for the adults to learn the rules and play a quick game so they’d be ready for the kids to arrive at a city park where the 3 courts were set up. That morning, there were over 80 kids running, laughing and having a blast as they played the game for over an hour. After lunch, the 3rd, 4th and 5th graders wanted to play again, and this time some of the adult volunteers joined in the fun. It was another hour of non-stop exercise and fun. I can’t imagine an easier way to have that many kids get that much exercise, and it was by far the most popular activity of the day.
A couple weeks later, my son brought an Ultimate Challenge Kit to a camp-out with his Boy Scout troop. One father commented that he felt the game would last about 15 minutes and the boys would be ready for something different, but they had to stop the game after over an hour of non-stop action. Then, the group of 12 to 17 year-old boys chose to play Ultimate Challenge again after dinner—and they played full-tilt until 9:00 PM when the adults insisted that they head back to camp for the evening campfire. The game was so popular, they made it the main activity of their troop meeting 3 weeks later."
Here is an article I wrote, featured in Water Safety Magazine this past January, that seems more than appropriate for this hot July weather. Enjoy! - Megan
"Here is some advice on when and how parents can support their children as they learn water skills.
When infants are 6 months old, they begin to have enough body fat to remain warm enough in a pool for up to 30 minutes. From 6 months through age 2 is the best time for Parent-Tot classes. Swim instructors will educate parents on the correct way to hold their child in the water to keep them warm and safe, and parents can demonstrate to their infants a joy for water through facial expressions and body tension. Splash a bit, drizzle water on your face, blow bubbles, and bounce gently while holding your child securely to help him/her feel safe but relaxed in the water.
Nearing age 3-4, when your child can hold the pool’s edge, follow commands, and swim comfortably with an instructor, your support will be most useful at home before and after lessons. Fill up a large sink or wide bowl with water and give your child a straw. Have them blow bubbles in the sink by exhaling out the straw, and then inhale through their nose without drawing water up the straw. Kids can also begin holding their breath and dipping their face in the sink or bowl while safely knowing they can stand up and out at any time.
For ages 3-5, fill your bathtub with 1-2 inches of water and have your child practice lying face up. When they become relaxed in this position, have them look slightly left and right to feel the water in and around their ears and face. Next, fill the tub another inch (face still above water) and have them breathe in and out deeply, filling and deflating their lungs to sense buoyancy and floating. Turn them face down (face still above water) to practice a straight leg or flutter kick. Have your child blow bubbles in the water through his/her mouth, nose above water. Allow them to dip their nose/eyes/whole face down in the water when they have mastered the straw breathing and bowl dips or they feel ready to try.
In any swim class, same age kids vary greatly in personality. In one group of swim students you will see those that are so adventurous they are dangerous, and those that are so fearful they avoid approaching the pool. This is where a trained swim instructor’s knowledge will be most evident, and your sideline encouragement (or discipline) regarding your child can support the instructor. Watch your child enough to keep them safe, but not so intensely they are uncomfortable and distracted. After a year or two of lessons and experience with a few different teachers, you will have more confidence in a selecting both a teacher and additional swimming skills for your child.
Water can be scary for small children. Give your child both encouragement and time; provide lots of love, support, and patience. Lead by example and blow straw bubbles in a sink, dip your face in the water, and model any water exercises your child is learning when possible.
Swimming skills are built over a lifetime of experiences; enjoy as many as you can together!"

It's time for summer vacation! Here are the items I pack every trip to reach my daily fitness goals, boost my mental health, and keep my nutrition on track:
Record Keeping: Pedometer, Running Watch, Note Pad/Pencil: My pedometer also has a clock so I can leave my watches at home. The Running Watchis great for my training runs as it tracks the duration, speed and distance of my workouts and more. I keep my note pad and pencil in my bag for monitoring my food, recording my workout progress, and journaling the fabulous memories during my vacation!
Hotel Room: Resistance Tube with Door Anchor, The Great Stretch Tubing Handbook: These replace the need to find a weight room, I can fit in a workout from 10-60 minutes long in the morning, noon, or night, and they weight under one pound combined in my suitcase. Awesome!
Hotel Pool: 2 Water Bottles, Swim Suit, Sunscreen: If your swim suit is a tank and shorts, they double as workout clothes in a pinch. The water bottles left empty and tightly-sealed create two dumbbells for under water (add water to the bottles to decrease the resistance/buoyancy of the floats).
Nutrition: Breakfast, Protein Powder, Vitamins, Snacks: Packing your own breakfast is great if you have no idea what food to expect on your trip. If you have a free hotel breakfast, hit up the milk section with your empty water bottles to make your protein shake post-workout. If the complimentary breakfast is great, you can save your packed breakfast for a meal replacement if you are on the go later. Also pack small, healthy snacks for every two to four hours to avoid excessive hunger and subsequent overeating.
Hotel Gym or Outdoors: Sneakers, Socks, MP3, GPS, Cell Phone: I like to travel in my running shoes but pack sandals in my suitcase for the pool. Bring double sets of socks; liners worn inside your cushion sockshelp prevent blisters from running workouts or excessive walking on your trip. Load your MP3 with happy, inspirational music to put you in a great travel mode. Try to research the area in advanced but a GPS is always handy for finding local gyms and parks in a new area. I carry a cell phone in case I'm able to sneak off for a run in a new place and run into an emergency.
Relaxation: Inspiring Book or Fun Magazines: Read these before bed or first thing in the morning. It is vacation; hopefully you have a bit of time to read here and there!
For Kids: Pack some Travel Music to entertain your family on long car rides, and pack empty balloons or extra socks and this link for fun travel games.
Recently on Facebook I shared my trial to cut down on my shower time. The main reason is that lately my "to read" pile is growing faster than I can keep up! My 2 year old has quit napping and my 5 year old is two months from Kindergarten. Luckily for the next blissful two weeks, I have 25 minutes of reading time at their combined City Pool swim lessons.
Here is the list on my bedside:
- Getting the Pretty Back by Molly Ringwald, p. 99
- Freedom by Jonathan Franzen, p.7
- Decision Points by George W. Bush, p.11
- A Hand to Guide Me by Denzel Washington, p.256 (almost done!)
- The 5 Love Languages: The Secret to Love That Lasts by Gary Chapman, p.33
When I see an interesting newly released book, I place a hold on it within my City library account. Then the library sends me an email when the book is ready to pick up. Often I put books back on to my "future reading list" and place it in the library return if I'm not keeping up, as you can see from the following...
A few of the books I wish to finish:
- My Spiritual Journey by Dalia Lama, p.141
- Lighten Up by Peter Walsh, p.39
- Extraordinary, Ordinary People by Condoleezza Rice, p.80
- The Life You Want by Bob Greene, p.45
- If You Ask Me: (And of Course You Won't) by Betty White
- Little Red Book of Selling by Jeff Gitomer, p.145
It is more unsettling to have a stack of unread books on my table than 3-4 I'm greatly enjoying at the moment. I keep track of unfinished books I return when new ones come in by writing down the page number I stopped at and adding the unfinished book back on to my reading list. And then there are all the magazines left unread around the house... that's a whole other story.

Our family of four is about ready for some hard-core outdoor fun. But I’m the first to say I know ZERO about camping well. This past Christmas my mission was to find (and impress) my outdoor-adventure husband with an awesome 4-person tent.
Since today is Father's Day, here are tent buying tips I discovered:
- You have to buy a footprint (tarp) for under the tent. It minimizes condensation on the inside floor and keeps rocks and debris from ripping up the bottom on the outside.
- With the exception of a water proof floor, the tent itself is water resistance/breathable. Get an added Rain Fly cover that is UV resistant to sunlight and water proof for rain showers. The Rain Fly should extend to the ground on the outside so sideways rainfall won’t come through your window seams.
- Shape is also important; a Dome is great for minimizing wind resistance but maximizing interior space.
- Bug resistant window mesh allows you to have bug-free fresh air, and a Vestibule is an area additional to the sleeping space for protecting your things, like wet clothes and shoes.
- A 3-season tent is best. 1-2 season is for near perfect and rainless weather; you only need a 4-season if you plan on camping in the snow. (Brr, no thanks!)
- Buying assistance varies on opinion of the sales rep. At REI, the sales man gave me a great tip that the packing weight of the tent could be split 3-ways among 3 people’s packs for long hiking distances. The sales rep at Sports Authority gave me the tip to buy the 20 lb/8 person/6 foot high tent so we could keep it up in the backyard, stand inside without ducking, and insert a king-size air mattress for sleeping comfort. (Oh baby, I was tempted!) The reps at Sportsman's Warehouse left me alone to cruise the display of assembled tents so I was able to climb around in and inspect all the models I saw online.
In the end I purchased this REI 4 Person Half Dome Tent. Fingers crossed that our camping experiences will be light-weight, dry, and spacious! If not, I also grabbed the REI membership for the lifetime warranty and exchange policy (ah, buying comfort!) With the tent (on sale in December), foot print, and membership, the total cost was $210.
