Aerobic exercise mode

Sticky

What is your preferred aerobic exercise mode? Do you even have one?

If you have decided to improve your cardiovascular fitness (heart, lung and circulatory fitness) what are your options?

Here is a list of 3 groups of exercise, intended to compare energy expenditure(calorie burning) and exercise intensity. If we are improving our aerobic fitness this means we are improving our ability to utilize oxygen. We need oxygen to transform stored energy into a form that our muscles can use to produce movement. When we move, we use calories. The number of calories we use will depend on our exercise intensity and the duration of this intensity. Check out the different aerobic modes of exercise to see what one you most likely would engage in.

(This following info was found in an article by Len Kravitz, exercise physiologist, called “Calorie Burning; It’s time to think “Outside the box” 7 Programs that burn a lot of Calories” and within that article he quotes the American College of Sports Medicine 2006 Guidelines for Exercise Testing and Prescription. I like this list of aerobic exercise modes because it is quite simple and to the point.)

Exercise mode Group I

Consistent intensity and energy expenditure that is not dependent on the participant’s skill level, eg. walking, stationary cycling, running, machine based stair climbing and elliptical training

Exercise mode Group 2

Rate of energy expenditure will vary, depending on the person’s performance ability. With higher skill levels, a person can work harder and longer. Examples include group-led aerobics(this is where Essentrics fits in), outdoor cycling, step aerobics, hiking, swimming, water aerobics, and inline skating.

Exercise mode Group 3

Highly variable in terms of energy expenditure, examples include basketball, raquet sports, and volleyball.

Now that you have thought about what is your preferred aerobic exercise mode, now lets look at effort.

Aerobic mode and exercise intensity (light, moderate or vigorous)

You can use the following to assess your exercise intensity:

Talk test (light=talking easy, moderate=short sentences, vigorous=1-2 words only)
Rate of perceived exertion (light=2/10, moderate=3-6/10, vigorous=7-8/10).
Percentage of Heart Rate Maximum (light=57-63%, moderate=64-76%, vigorous=77-95%)
Sweat and heat. When it comes to aerobic activity, heat is one of the by products of aerobic metabolism.

Goals in minutes: 150 moderate or 75 vigorous?

The World Health Organization has made these guidelines for weekly accumulated exercise.

Depending on your mode, you may be tapping into light, moderate or vigorous intensity levels, or a mixture of all three.

For activities in group 1 aerobic exercise mode, using the talk test or rate of perceived exertion is possible and easier than it would be for a variable level of effort. You can modify your workload (speed, resistance, incline on a treadmill) to attain your goal of moderate or vigorous intensity. Some warm up is necessary.

For the group 2 or 3 aerobic exercise modes, it will probably be easier to use a heart rate monitor and app to determine if you are hitting your weekly goals.

As always, you need to check with a health professional first if you have any concerns about exercising as it relates to any current health problems. You can also use something like PARQ Activity readiness questionaire or CSEP Get Active Questionaire to help you figure out if you are safe to exercise.

Aerobic mode
+exercise intensity
+weekly goal

If you have figured out these three things when it comes to your cardiovascular fitness, then now it’s time to put the plan into action.

Here is an example of how I attain my weekly goal of 150 minutes of moderate intensity exercise:

Treadmill jogging at moderate intensity 12 minutes 4X/week 48

Essentrics 2 x/week 20/60 minutes moderate intensity 40

HIIT style exercise class 20/60 moderate intensity 20

Circuit training leg machines plus bodyweight exercise 12 minutes 4X/week 48 (warm up is treadmill jogging)

Total 156

I will add that I had to recently modify my workouts to attain the 150 per week. I used a HR monitor and app to figure out exactly the impact of my weekly training and noted that the weighted/machine workouts needed higher intensity activities interspersed throughout (like mountain climber, jog on spot, step ups fast pace, and other plyometric type exercises) in order to keep my heart rate up. The pace of the machine exercises had to be sped up a bit as well(more volume in less time).

Does it have to be so complicated?

Of course not! I just like to work out the details and make calculations. You only need to keep it real if you want to have an effect on your current fitness level. Trust me. It is challenging but never impossible. Check out my blog on Keeping it real: Physical fitness and VO2max if you need a little peer support and pep talk.

Increasing energy with exercise

Increasing energy with exercise:  How does exercise increase our energy?

VO2

Improving the fitness of the heart and lungs through cardiovascular/aerobic exercise increases our VO2.  The higher our VO2 the more efficient we become at creating energy for ourselves by combining oxygen with glucose to make ATP.

Heart

Increasing fitness will increase the strength of heart. The heart can work more efficiently, expelling more blood with each beat.  More blood = more oxygen which means fewer beats required for any activity that increases the heart rate.

Strength

When we improve the strength of our muscles we do not need to max out our muscular effort.  If we could only lift 10 lbs of groceries, and now we have increased our strength to be able to lift 15 lbs of groceries, the 10 lbs will seem easy, with less effort required.  Therefore, more “energy” will be left over for other activities. 

Endurance

The same goes for endurance of a muscle.  I had a colleague that was used to treating shoulder problems. She decided to help out on the post-operative floor getting patients out of bed.  Half way through the morning, her back was sore and she needed a break.  The endurance of her back muscles was not sufficient for the task at hand.  Her back muscles were out of gas before the morning was over.  

Flexibility and range of motion

Having the flexibility and range of motion needed for a task will help conserve our energy bank.  For example, if you sit a lot, and have tight hip flexors (quad/psoas), every time you try to stand straight, there will be some relative resistance to standing straight.  This ultimately results in an increased use of our extensors(back and hips) and may make standing straight more effortful.

Endorphins

Endorphins are released during exercise and can make us feel lighter and brighter on a physical and cognitive level . Endorphins can also decrease the experience of pain. This may result in a reduced level of stress, leaving more energy for other tasks.

Summary and support!

Exercise will increase your energy levels.

Exercise resolutions 2023

Leave a comment

Not sure where to start with your exercise resolutions 2023? No pressure. I will go first:

First, my exercise evolution update

With the exception of the last 7 days, my routine has been pretty consistent and I look forward to resuming and evolving my program in the new year. In short, I will be continuing with lunchtime cycling, after work stretch and strengthening (machine, body weight and theraband, primarily legs), twice weekly Essentrics® class(teach), teaching a new mini class Wednesday am, weekly HIIT online class with my exercise peeps, and walks to and from work (get the snowpants out!)

I have some more specific goals that are exercise related:

A) I want to retest my VO2 max with a step test (Modified Canadian Aerobic Fitness Test (mCAFT)). Not sure what VO2 is? Check this post.

B) I want to retest my heartrate level during my fitness classes to see if my past calculations on time spent in a moderate intensity zone is accurate.

C) And I am strongly considering the dabble. This involves an in person or perhaps online ballet class. It will be very interesting to see how the class feels as it has probably been about 12 years since I have stepped into a dance studio. In person would be ideal as well as my biggest challenge. I will keep you posted.

Now for you.

If you don’t have any ideas, check out some of my past posts:

Q: Would you like to find out where you are on the exercise and activity spectrum? If you know where you are, you might be able to envision where you want to go.

Q: What do you want, what do you need? Check out Exercise Specificity.

Q: Do you need a story to get the ideas flowing? I’ve got a couple: The evolution of a group exerciser and Keeping it real.

I am going to open up the comments so if you wish to post your exercise resolutions or activity plans for the 2023 please do. It can be simple or with some detail.

If you don’t have any resolutions, don’t worry. The beauty of exercise and physical activity is that you can start anytime you want. Whenever you are ready. Exercise is one of those things that for many of us has its ebbs and flows. No guilt required.

And if you need help, find some help. Follow up with your favorite health practitioner or fitness professional. Complete an activity readiness questionnaire if you have any concerns. I plan to provide you with more structure and support, so feel free to join my email list for further updates very soon!

Are you ready? Then get set! Let’s GO!!

Exercise program design ABC’s

Exercise program design

Let’s talk about exercise program design! When you have decided to exercise, what next? Need a little structure? Check out the following ABC’s of exercise design. Use your current movement repertoire to fill in the blanks.

wArm up

Body of workout/main goal/target area/target activity

Cool down or release

Part A

Warm up:

Start with easy, repeated or rhythmic movements that are gentle and suitable to your current fitness level. To see where you stand on the exercise and activity spectrum, see post Are you evolving as an exerciser?

Your warm up may include using cardio equipment like like a stationary bike or treadmill. Your warm-up could also be components of your main workout done slower in a smaller, gentler range to start.

Use your warm up to transition your mind and begin directing your focus to your body and how it relates to the physical space around you. “Let go” of the tasks that you were recently involved in or one’s that you need to do later.

Vary the intensity, by changing the speed slightly or use progressively larger movements.

These are all options. You can do what works for you. If you are not sure, consult someone who should know how to help you find and narrow down your options.

Part B

“Body” of workout/target areas/target activity:

This part of your workout may be where your goals come in to play:

Do you want to get stronger, more flexible, less stiff, have more endurance, better posture, better cardiovascular fitness, or improved balance? Is increasing the amount of movement at a particular joint important to you? Do you need to relieve stress? Check out Exercise specificity: what do you need?

You could focus on a part of your body (upper body vs lower body, back body versus front, arms and legs, spine and core)

You can also look at specific workouts already out there that meet your needs (Pilates, Yoga, Barre, Zumba, HIIT, TRX, Spinning, Interval training, circuit training, Essentrics®, weights).

If you are not sure, talk to someone who should know (family doctor, chiropractor, trainer, physiotherapist, massage therapist, kinesiologist, naturopath, or other health care or fitness professional).

Part C

Cool down or release:

This could be a progressively slower version or less intense version of what you were just doing (you were jogging and now you will walk). Kind of like your warm-up but in reverse.

Often cool downs will include stretches of the muscles that were used in the workout, which could be static or dynamic stretches. A cool down allows the temperature of your body to decrease slowly and if you got your heart rate up, to slow it down gradually and allow the muscles to return to a normal level of circulation.

It may also be the time where you feel the most relaxed and released and if that is the case, go with the flow and stay focused on the here and now.

To stay in the moment, something like diaphragmatic breathing (belly breathing) can be used to center yourself and release even further.

Before I give you my exercise evolution update, I just to let you know that I am livestreaming weekly on all topics exercise on Facebook!

Join me for “Tea & Exercise: Livestream Chat with Andrea” @andreanunnexercise Wednesday mornings at 9am on Facebook live

There will be a fun physical demo along with a brief chat. Follow my page on Facebook to keep up with future topics and updates!

Update

I haven’t published an exercise evolution update for awhile. The last one was back in January. I have adjusted my routine so I do at least a portion of my workout at lunch, which leaves more time available for other things in the evening.

I have maintained relative consistency in my frequency which, for me, is the most important thing. It’s easier to scale down and then back up versus falling off the wagon completely. I’d rather do a little less to suit my current schedule than nothing at all. Here is my latest weekly routine:

Lunchtime 4x per week: 22 minutes of cardio MT 80 (MT=minutes spent at moderate heart rate intensity. For more discussion on moderate heart rate intensity activity, see Moderate intensity exercise. Where do you find yourself? )

I have monitored my heartrate manually to make sure I get into my moderate heartrate zone, which is above 109 beats per minute.

Daily walks to and from work 25 min each.

Essentrics teaching 1hr 2x/week MT40

Saturday endurance/HIIT class MT 20

2x week weighted workout: leg press and ham curls plus step exercise, 12 minutes. I have not been diligent at keeping my heartrate up, but instead focusing on pain free movement.

2x week sliding lunges plus “glute medius” work in standing and side plank with theraband. Again, heartrate has not been focus but painfree motion and ideal alignment.

This week I developed some new choreography for my classes. This usually takes an additional 3-4 hours of intermittent activity.

So I am just under my the goal of 150 minutes of moderate exercise based on recommendations from CSEP Canadian 24-Hour Movement Guidelines for Adults (ages 18-64 years). Now that I have re-assessed, I will figure out where I will make up that extra 10 minutes that I am missing! Keep it real and don’t worry if your routine doesn’t go exactly as planned! Get out into the activity sphere everyday and something will get done! Are you ready? Then let’s GO!

Exercise and injury: We all have our limits

Why do we injure ourselves?

Did we do too much too soon? Did we go beyond our physiological limits? Maybe we have an underlying problem that keeps resurfacing? Maybe there is something going on in our biomechanical bodies that we are not fully aware of or understand. Maybe we have been a consistent exerciser and have been doing the same thing for years? Did you try something new and didn’t really know the basics? Are you a weekend warrior?

Tissue tolerance

Exercise and injury. There are a multitude of possibilities. But I would say in most cases, we have exceeded our tissue’s tolerance. Not a great layperson term, but it kind of summarizes it all into one box.

Our bodies our made of different tissues, and I am speaking very generally from a biomechanical perspective: we have bones, joints, muscles, tendons, ligaments, blood vessels, fascia, skin, and nerves that represent the physical entities that make up our musculoskeletal system, the one that moves our limbs, maintains our posture, allows us to move from one place to another, fidget or reposition, and of course carry out out daily tasks(even sedentary ones) as well as exercise.

We exercise to keep this system primed and ready for action. The less we move, the more limited our movement repertoire becomes. By checking in with your body regularly, responding to and modifying our physical routines, we are more likely to get the balance right.

Exercise and injury. Think about the following :

Consistency of exercise (how regularly do you exercise?)

Volume of exercise (number of repetitions or repeated movements in a session or specified time frame, eg. number of steps in a day)

Impact (high or low impact, which one do you do?)

Range (does your flexibility or available joint movement match what is required for your chosen activity?)

Force or strength requirements (are you loading a tissue too little, just right, or too much? It depends on your goals)

Frequency (do you have rest days in between workouts? Do you workout once a week or daily, or work different parts on different days?)

Technique (what are you doing, why are you doing it, and what is the best technique, alignment, speed, rhythm, or range to do it at)

The above list is very generalized, but you can see there are multiple modifiable factors that can affect the tolerance or resilience of our tissues, and in turn, when it results in injury or having “overdone it”.

If you are a high level athlete versus a grandmother who takes care of her grandkids, you will likely have different goals when it comes to your fitness and lifestyle. Try not to compare yourself to others when thinking about what kind of program you should do.

See my blog called Exercise specificity: what do you need? for help in figuring this out.

Let’s be realistic

Exercise and injury do not need to go hand in hand. I think in many cases our ego gets the better of us. Or maybe it’s our memory (or inserted memory, a.k.a. delusion). Our inability to be in the moment with our bodies may result in participating in an activity in a manner that was better suited to a younger version of us, many years or even decades ago. In this case, re-evaluating how you feel during or after your activity of choice may help you refine and remodel the way you do things, matching it more closely to your current abilities or physical capacity.

Training

If you know you are training for a future event which will require a level of fitness that exceeds your current fitness level, educate yourself, use common sense, ask questions and look for advise from those who appear to be successful in the same activity. This may increase your odds of avoiding injury and completing your goal. I think one of the best things you could do is be realistic on time. Give yourself more than enough time to prepare for the event.

Fuel

We know that the resilience of our tissues also depends on the fuel we use to sustain activity and to build and regenerate new tissue. This gets even trickier, as there are so many views on nutrition, and everywhere we look there is advise on how to best address this. Find someone you trust and whose perspective is similar to yours when it comes to food choices. Start with the obvious by making healthy food choices(i.e. avoiding junk food, highly processed food). Eat what you know is healthy more often.

Consistency

Exercise and injury. My last thought is think about consistency. If you only dabble in exercise or in intentional physical activity once in a while, start with one day a week, or one activity that you can do well. Develop a basic schedule that you can stick to. Find a place for it in your calendar and make that the beginning of your “exercise week”. You may find that planting the seed (deciding when, where , what and how) and then cultivating it (completing it at the beginning of your “exercise week”), may result in new “buds” in unexpected areas.

Motivation to exercise

Exercise for the most part should be fun. If you hate it, maybe you are doing the wrong thing. The options when it comes to exercise and physical activity are endless. You don’t need to fit into any mold. If something works for you, stick with it. Then see if there are ways to expand your horizons, and switch it up a bit.

If you really do not know where to start, talk to someone who should know, and don’t feel intimidated. It doesn’t take much to get moving. And once you find the beginning of your path, it could take you anywhere.

It’s OK to “start over” many, many times. Keep at it, and soon you will feel something stick. You’ve got to move, and I have no doubt that you can do it!

Let me help you get started

If you need help, accountability(and I mean this in the lightest sense) or just to know that you are not alone in your exercise journey, join me in September for weekly motivational movement, exercise demos, conversation and fun! It won’t be complicated. Stay tuned!

If you are ready to roll, check out my page, Essentrics with Andrea. It could be your starting point, or maybe it will be something you can try later. In any case, take charge and join my email list. I will send you future blogs and the latest updates on my scheduled livestreams.

Anatomy, physiology and aging, Mental health & stress

Muscle tension

Have you noticed that we use the same words for “good” muscle tension and “bad” muscle tension? What’s the difference?

Here are two types of muscle tension:


1) A muscle has to generate tension to exert force at a joint. This may or may not result in observable movement. This is what we do when we are trying to strengthen or contract a muscle. This type of muscle contractions could be concentric (muscle actively shortens), eccentric (muscle actively lengthens against a load or gravity) or it could be isometric (muscle length is unchanged during a contraction).

2) A muscle that “should” be at rest but is still generating tension and/or movement. This may be the type associated with mental stress. Areas where we may feel this “tension” is the neck, jaw, hands, chest and abdomen. It really could be any muscle. We may tighten the muscles in these areas inadvertently in response to stress.

Either way you look at it, muscle tension is created through muscle contractions, voluntary or involuntary, done consciously or unconsciously.

So why should you care?

Because we have control over both types of tension, even the one that seems to be more “unconscious”. And one of the best ways to learn how to “release” or “exert” muscle tension is through exercise. Exercise helps us to increase our kinesthetic awareness. More simply, exercise can help us feel and understand our bodies better, and become more adept at modifying muscle tension according to our needs.

Even better, if our focus is to “release” tension, there is a reciprocal inhibition of one muscle over another with every muscle contraction. This means, if I want to release tension in my tricep (located on the back of my upper arm) then one way to do this is contract the opposing muscle (bicep) on the front of the arm.

Do you want your muscles to get stronger to improve function or do you need to release and learn how to “let go”?

Probably a bit of both. So why not move with intention at least once daily? This could be a walk, an exercise video, an exercise class virtually or in person, a personal training session, swimming, or multitude of other physical activities. Start with what is familiar and preferably at least mildly enjoyable. Buddy up with someone who is looking to do the same thing.

When you exercise regularly or intentionally move on a consistent basis, you will slowly learn more about your body and how it feels after certain activities. You will become better at determining when a muscle is “on” for the purpose of strengthening, or if it is “on” because of habits that have connected our mind’s stress to a physical response in our body.

If you would like to learn more about your body through movement, Essentrics is a great place to start. Essentrics uses all types of muscle contractions and will help you zone in on areas where you need to release.
