It can be really hard to be motivated to exercise. Much like most people in today’s society, we throw ourselves into a fast paced world where work, family and life are not always balanced. We are typically overtired, our to-do lists overflow and we tend to still say yes to things we maybe shouldn’t. On top of all this, we get told we need to look after ourselves. Eat well, move often, become more mindful etc etc. It is seriously tough stuff!
I know I should but I just don’t feel motivated to exercise!
I have recently gone back to study and I find myself sitting long periods attempting to use my brain (it’s hard work). By the end of the day, I am worn out. I am not sure what you feel like, but I feel like I have run a marathon. All from the confines of my small desk. Although I preach the joy and benefits you get from moving your body, to be honest sometimes it is the last thing I feel like doing. I want to go home, tick off annoying to-do list items and then if I have time I watch Netflix and cuddle with my dog.
Here comes the big but! I am a member of a pretty rocking hockey team and we train consistently on Tuesday and Thursday nights. So, no matter the weather, or how tired I feel, I peel myself off the couch and head out.
The tide turns once I move my body!
During the first 5 or so minutes, I am still not super excited to be running around but then a miracle happens. Slowly, I start feeling better, my energy returns, I don’t feel miserable and I am actually happy. We all tend to leave training in a better mood. I get home and tick off some to-do items and then I happily pass out for the night. I sleep really well, not only because exercise helps regulate my circadian rhythm, but because I know I have made my 10,000+ steps.
Acute changes to exercise: It is not a miracle, it’s science baby
- Exercise acts directly on our central nervous system to increase energy and reduce fatigue. Notably, the improvements in energy and fatigue are not related to increases in aerobic fitness.
- When your heart rate increases acutely it increase the brain’s blood supply. This makes you more alert, enhances your motivation to complete focused tasks, and improves mental clarity. It even creates neurons!
- Acute stress levels decrease post one exercise session thanks to increases in hormones that makes us feel awesome (serotonin, norepinephrine and dopamine). If you want to know more, read Jacinta’s blog on exercise, mood and stress.
- Also, psychologically we have achieved a mini-goal of exercising for that day so our confidence thanks to our sense of accomplishment (cue no internal guilt trip)
Some tips to help you beat the motivated to exercise fatigue barrier?
- Get into your active wear. It helps.
- Even if you don’t smash it, just show up. Something is better than nothing and you never know, it may become amazing.
- Ask yourself: Are you really exhausted or are you just tired (exhaustion may need sleep, tiredness/fatigue may need exercise)?
- Have an appointment – whether that is a group class, a specific time in your diary, an appointment with your EP/PT.
- Think about what you will feel like both during and after. You won’t regret it!
About the Author
During one of the group classes last week, I was engaged in a delightful conversation about a client’s 70th birthday. He was shocked he was turning the big seven-zero and when asked why he just responded…“Because I don’t feel it.”
Interested, we prodded him further, “well, how old do you feel?”
“I don’t know, I feel like David!”
The outcome of this conversation was a thought provoking statement. Training for him was not about getting stronger but more about enjoying retirement. Essentially, he now feels like he has a new lease on life. He never believed he would enjoy retirement as much as he does and he puts this down to staying mobile, strong, and injury free.
The road to retirement
From the age of five (give or take) where we start our official schooling through to the upper echelon of our middle age, we are expected to work in some shape or form! Apart from some in their twenties who go exploring, we are usually tied down to the monotony of work life. We all sit at our desks day-dreaming about the life we are going to have when we retire. However, we almost forget that when we arrive to this magical destination, we are 60-70 years of age. Over that time our bodies have been ignored, battered, bruised, sat sedentary and fed truckloads of processed foods.
In our field, we tend to see 60 to 80 year old clients with conditions such as osteoarthritis, diabetes, obesity, and heart conditions. All of whom still want to get out and live out their retirement dreams. Not just sit on a couch watching re-runs of “The Bold and the Beautiful”. However, the condition that their body has arrived to retirement in has made this difficult (but not impossible).
So how do we do we move well enough to start ticking things off our bucket lists?
Training for retirement – when you are retired!
Never fear! Just because you have spent a majority of your life working and caring for others doesn’t mean you may as well give up and switch the TV on. A majority of people want to walk around Europe, become grey nomads and see amazing sites like Machu Picchu. This involves feeling comfortable climbing stairs, walking long distances, balancing on uneven surfaces.
Hopefully we get to experience the joy of being a grandparent. Being about to get up and down off the ground, pick them up when they want a cuddle and kick a ball around the back garden is very difficult when you are not fit and active. Add to that, keeping a nice house and garden without aggravating injuries is a pretty big deal.
So therefore, we need to ensure we have adequate aerobic capacity to move for long distances. We need strength in our glutes, quadriceps, trunk and the list goes on to climb, hop and carry all sorts. Lastly, we know balance and reaction time does decrease with age so we need to challenge it (safely) as often as we can. We need to move well to retire well!
It is never too late to start!
Training for retirement – while you are still working!
Why wait till we get there to deal with the implications of a taxing work life? Improving your movement capacity and remaining injury free doesn’t just mean love retired life. It means you can love life in general! But it also means you can love life in general. Increasing your muscle strength, fitness and mobility ensures you can complete day to day life with decreased amounts of fatigue, you can hike without pain, you can umpire your children’s soccer games. Seriously, what more can you ask!!
Have you ever been too tired to walk up your stairs, eat, or even go to the toilet? Welcome to the life of individuals with cancer related fatigue.
Fatigue is one of the most common and debilitating side effects of cancer treatments that presents itself before, during, and after treatment. A 2007 study found that 80-90% of people undergoing radiotherapy and chemotherapy reported experiencing incapacitating fatigue. Of those, approximately 91% felt they could not lead a normal life, participate in social activities or perform simple intellectual tasks. 75% had to change employment status and 65% needed their caregivers to take at least one day off per month. Worse still, many of these people can suffer similar symptoms long after the treatment has ceased.
What is cancer related fatigue?
Cancer related fatigue is unlike anything the apparently healthy individual has usually ever felt. The sense of utter exhaustion that you feel is disproportionate to the amount of effort produced. For a once fit individual, that can mean that a walk to the letter box produces the fatigue levels that are only imagined after completing an Ironman event (1 x 3km swim, 1 x 180km bike ride topped off with a marathon). The most disconcerting thing about cancer related fatigue is that rest or sleep does not always help alleviate symptoms. On top of that, because the causes are not well understood, treatment is not always straight forward.
If that is that case, shouldn’t I rest rather than exercise?
Well this is where it gets interesting! Research has now shown that exercise should be used as part of a patient’s oncology treatment schedule. Not surprisingly, results show an increase in strength and capacity, especially in cases of breast, prostate, haematological, and colorectal cancer. However, one of the unexpected outcomes of these studies has been the effect of exercise on fatigue levels. It was first measured due to concern that exercise would exacerbate cancer related fatigue levels, BUT the results proved very interesting… It in fact showed the opposite!
A systematic review from South Australia showed that out of the 47 studies identified relating to exercise and cancer related fatigue, 32 found exercise to significantly reduce cancer related fatigue! In fact, there were no significant studies that didn’t favour an exercise intervention for improving cancer related fatigue.
So… exercise reduces your levels of cancer related fatigue!!
How exactly can exercise help?
As there is still no single definitive cause of cancer related fatigue, determining the physiological reasons as to why exercise is so effective is pretty difficult. When you begin treatment, just the thought of exercise would probably make you feel exhausted. However, if we look at the flip side, we know that without a doubt inactivity leads to increased fatigue. Exercise reduces the distance you can walk without puffing and also the amount you can lift. So therefore, movement allows you to complete all those activities quicker and for a longer period of time.
There are also theories around surmising that resistance training can prevent the dysregulation of our immune system and helps maintain our energy currency (ADP). All of which can be disrupted when we begin muscle wastage. Big words I know! The main take away message is that moderate exercise can increase your capacity to function, improve your quality of life, decrease risk of depression and anxiety, and decrease cancer related fatigue!
What exercise should I do to reduce fatigue levels?
Before we answer this question, I would like to make a caveat… The definition of exercise (and its intensities) is very broad. What a healthy individual calls exercise can be different to what someone undergoing treatment or who is now a survivor does. Also, no two cancers are the same and so no two exercise prescriptions are the same. It should be based on factors such as your cancer diagnosis, side effects, and treatment type, timing and trajectory. Plus your age, current activity levels prior to diagnosis and previous injuries and illnesses.
With all that in mind, research has shown that a combination of both types of training is recommended for you during and post treatment. So far the evidence says that best case scenario is twice a week progressive (60-80% 1RM) resistance training (lifting/moving heavy objects). Adding to two-four times of moderate aerobic (huff and puff) exercise (40-60% max). If you have just undergone a chemo cycle that may be 2 x 5 minutes of a home-based program. This may include sit to stands, wall push ups and a single leg dead lift. If you are feeling strong that maybe 2 x 45 minutes of supervised gym using weights.
Do I need to train throughout my whole treatment?
Interestingly, timing and duration of the activity may be important since one of the biggest effects on fatigue was observed when the exercise intervention lasted until the end of the treatment. So, ensuring you move throughout the entire treatment period/s can decrease your cancer related fatigue by up to 50%. That could mean the difference between getting to the toilet, being capable to watch your children play sport, or even feeding yourself.

“Give me abdominal exercises to lose fat around my stomach! Can I do triceps exercises to get rid of my granny arms? These are statements or questions I have heard more times than I can count. It is a question steeped in marketing, wishful thinking and a desire for that society driven “six-pack” and or “buns of steel.” The “spot reduction” theory is based around the act of selectively reducing fatty deposits in targeted areas by exercising the specific area. It seems logical to an extent. If a client works a muscle, then the fat around the area is used to produce the energy needed for the movement.
Unfortunately this is not the way it works!
If only it was that simple!!
Let’s briefly look at why we burn fat from the whole body:
When we need to complete a movement… say climbing a set of stairs
— We use glucose (carbohydrate) as our first pick to create/fuel a muscular contraction/movement.
— This glucose is either floating in blood stream or the liver (which stores glucose) gradually releases it into the blood stream.
— Once the glucose runs out, we tap into our fat source by way of a signal from the brain. This results in a release of triglycerides.
— This literally breaks up the fat cell (triglyceride) into a fatty acid and a glycerol molecule. The fatty acid the travels through the circulatory system, to the heart, liver and /or lungs (if blood has time to be oxygenated).
— From there it heads to the working muscles where it goes through a process to release the energy to make movement
— No matter which muscle needs the fuel, the molecules (fats, carbohydrates or proteins) travel around the circulatory system.
So all in all, it is not as easy as grabbing a fat cell from the specific muscle and using it’s energy. It is essentially easier and more efficient to steal those fatty acids from everywhere. We can’t choose where we lose our fat from. Sorry guys!
There is research to back up this idea.
In 1984, a study found that a sit-up program does not preferentially reduce fat cell size or fat thickness in the abdominal region in comparison to other body sites. In 2007, another study determined that an upper-body program resulted in a generalized loss of fat mass rather than specifically the upper-body. Finally in 2013, it was found that training a single leg was effective in reducing fat mass but not specifically in the trained limb. This was determined using a whole body DEXA scan, which is the current gold standard for determining fat mass.
So what helps reduce waist circumference (fat mass)?
From that exact research gives us a clue. Each of those studies looked at a different body part (arms, abdominals and legs) and all had an effect on the bodies fat mass. So, if we completed a whole-body strength program we would see an effect over the whole body. Whilst getting stronger overall in the process.
It is a win-win!
Furthermore, from an energy balance perspective, completing exercises incorporating large muscle groups in big compound exercises creates greater energy deficit. These are exercises such as the squat, deadlift, bench press and rows. Why?
The more muscles used in one movement, the more fuel (fat/glucose) it needs. Just doing a sit-up, which works abdominals, look at a squat which can use legs, glutes, abdominals etc. You will also produce less fatigue and therefore complete more exercises by looking at a whole body approach. So rather than looking at 1-2 abdominal exercises to lose weight, try variety. We encourage clients to complete aerobic exercise, some resistance training and any incidental activity your heart desires. Plus think about the quality and quantity of food and drink you consume (but that’s another story).
Most importantly, stop getting fooled by those marketing departments. Also throw out that ab-cruncher that is collecting dust under your bed! Please!
