Welcome to part one of a six part series about applying the principles of exercise physiology to improve fitness and performance – both in sports and life.
Whether it’s designing a program for general fitness or developing a program for a specific sport, event or athlete, exercise scientists usually abide by six principles of conditioning. All of these principles have been scientifically proven to enhance athletic performance, provided they are applied correctly.
Let me introduce you to the first principle…
“The Principle of Individual Differences”
We are all born with a unique genetic blueprint and anatomical structure – thus there will be individual variations in response to a given exercise or training program. Thus, what ‘works’ well for one person may not be appropriate for another.
When general fitness guidelines are applied, most people do get fitter and stronger – however, what if you wish to take it one step further? This is where individualized fitness testing can really help. For example, it’s a worthwhile investment for a serious recreational or professional endurance athlete to know their VO2max or aerobic power index, tested on equipment that is specific to their sport. This way, a program can be tailored to individual need based on heart rate, anaerobic threshold etc.
Knowing body somatotype and looking at anatomical structure may help determine if an individual is built for strength and power sports or endurance events. Many elite athletes have been identified as potential talent in their chosen sport whilst still at school, thanks to talent identification programs that are run by institutes such as the AIS.
In the practice of yoga, knowing and understanding anatomical structure can help determine whether someone has the potential to be a good back bender or if it’s in fact possible for them to achieve a lotus pose. In other words, an understanding of individual differences in anatomical structure can help prevent potential injury in class.
Genetics play a role and it was possible a few years back to determine an athlete’s response to body fat metabolism, recovery, nutrition and preservation of lean muscle mass. I did the test in 2007 and used to perform analyses for others, but am not sure if the testing is still available in Australia. Some people need more time to recover than other people and age (sob!) is also a factor in determining recovery time.
Postural differences between individuals will also determine how an exercise program is prescribed. For example, many people have poorly developed posterior chains (the musculature along the back side of the body) due to poor posture and poor lifestyle practices – thus need more consideration than a “3 sets of 12, let’s work every body part on a machine” training approach. Individual differences in physique guarantee that most gym “machines” are next to useless.
Getting the most out of the “Principle of Individual Differences”
- It’s worthwhile investing in specific exercise testing for your sport if you’re keen on taking your performance to the next level
- Have a look back at your history – have you always been better at sprinting or working over longer distances? Do you gain muscle easily? If you cannot afford testing, history often gives clues as to what sport or activity you’re suited to.
- Have your posture checked out – wanting to run, but getting knee pain? Or getting frustrated that your back hurts when you try to squat? Often pain, particularly the chronic variety, is driven by posture-less-than-becoming. Of course, the correct technique is essential – but leaving that for another post.
- If you’re new to exercising and want to find a class or activity that suits you, it’s worthwhile getting someone in the know (eg exercise scientist or physiologist) to have a look at you – often looking at someone can be quite telling – as to whether they’ll enjoy hockey or distance running – on physical stature alone.
As you can see from the picture above, individual physical differences impact markedly on the sport you choose to play.
As for me, I’m a bit of an all rounder – I’m not particularly excellent at anything, but I’ll give anything a try and put in a reasonable effort.
What about you? Do you know what sport you’re made for?

I’ll look forward to this series Liz
And I love this first part, especially as I think we would all be a bit happier if we accepted that we were good at certain things and not so good (and not *meant* to be so good!) at others. I am not made for ball games, but think I’ve got it in me to run and do sports that benefit from ‘slow twitch’ muscles.
I’m not one for ball games either!
I’d like to start working with my body and doing what it’s best suited to. What’s your opinion Liz? We worked together for quite a while and you saw how I responded, so what do you think? I was never any kind of athlete as a child, so I kind of skipped that part
Hi Amanda, from what I remember, I’d put you somewhere in the middle – probably leaning more towards the sprint/track type stuff just based on body type and response to the training we did together. Of course with cycling there’s lots of technique and probably just as much, if not more for the track than the road.
Thanks Liz. I do struggle a bit with enduro. Onwards and upwards with track. I don’t feel I have the attitude (aggro/need to win) for competitive sprint on the track though – that stuff is just scary! Maybe I can specialise in the Individual TT – both track and road?
I think TT would be perfect -you need a bit of mongrel to get the job done and a good smattering of faster twitch fibres
That’s my current weakness, sustaining a big gear, big effort over a longer period of time. But I’ll get there in the end
I’m just enjoying getting better!
Getting better really is a good feeling, huh?
I saw that picture when I was writing about different types of fitness etc recently… Am looking forward to your series!
Deb
Thanks Deb!
Hi Liz! I also look forward to your perspective in this series.
I generally do agree with your body type discussion. I’m big boned and very broad shouldered, so heavy weightlifting is a very good fit. Even in yoga, my best poses require more strength and balance and less flexibility. Long-distance running, comprised of those slender people gliding around is not so good for me. However, none of this should stop a lighter boned person from weightlifting or anyone from running if it is special to them.
However….I’m also constantly surprised at how much I can do because I learn fitness principles and keep trying–many many times! Regarding back bends, a few years ago, I could not lift my body into an “up bow.” However, I kept practicing and eventually my shoulders got a little more flexible. One day, I could do up bow–a low up bow, that less flexible people do. Months later, I could do a higher up bow. Still months later, it got higher, due to practice and slowly gained flexibility. One day, after getting very high up bows, I tried a back bend from standing position and it happened. Now, over 50 back bends later, I believe that we should try more than we envision our bodies doing. I never thought I’d be doing back bends at 44 years old. Sheer willpower sometimes makes up for somewhat- lacking body structure.
Hi Marion,

That’s a fantastic story of yours and gives me hope for back bends myself one of these days
I’m going to throw a spanner in the works here and say that my individual variation makes me want to choose what it is I am least likely to be suited to excel in and work on that. I have found that while I am intellectually suited to dry, analytic theories, I NEED the opposite to balance me, so that is what I gravitate to. I find the same for sport. I was recently told by someone experienced that I am a string bean and muscle gain will take a long, concerted effort. So, guess what? I am doing it. Not out of spite, but I excel when a barrier is put up. Don’t stop me. I’m on my way.
Hi Kate, nothing wrong with what you’re doing at all. Does it make your heart sing and lift your spirits when you do it – if it does, then it’s the perfect activity for YOU

That’s great advice Liz – love what you do
Aw thanks Amanda, that’s very kind of you xx
Yeah baby! Full steam ahead.
Good for you chica
I know I’m not exactly built for running. I don’t have a natural runner’s physique or endurance. BUT what I do have is a love for the sport and how it makes me feel so it makes all other aspects irrelevant. I know I’ll never be elite but at my age just getting out there and doing it makes me a champion
My sentiments exactly
I’m looking forward to this series.
I’m not really sure what I’m ‘build for’ but I know I struggle with explosive-type moves that are needed for things like high jump etc but I’m not sure if that is physical or mental as I always fear missing the bar (or in the case of box jumps, the box) and hurting myself.
It’s not really cut and dried – what we’re all built for – we’re usually a mixture of somatotypes and muscle fibre types – I’ve always pegged you as being better at quicker faster activities than long slow endurance
Great start to what will be an interesting series of posts. I wouldn’t say my physique, at the moment, is a runner’s body, but I absolutely love running and the endurance stuff really suits me. However, to further your point of trying to find out what a body excels at, it will be interesting to see where our dietary and strength training experiment will take me. And as for trying road cycling, maybe I’ll find I’m better on the bike than on my own legs?
Whatever happens, I think I’m happy at loving anything fitness and giving it my best, despite not always looking the part… Although, having a smokin’ hot body would be fun too
Hey Emma, I think you’re an all rounder – and you’ll naturally gravitate towards what really suits you
It’s not all that cut and dried really
Touche.
Hey Liz! A great start to the series, and I look forward to more. Will you be getting into any particular in-depth series on certain aspects? As usual, I find it fascinating, and with what you’ve educated me about over the last couple of years, it becomes even more fascinating.
At some stage, I’d like to re-introduce my martial arts. Hopefully, I’ll work out a nice balance eventually. Anyway…thanks again & I look forward to your next post in the series.
During my early adult years, training in martial arts I think suited me perfectly! I look forward to going back to more martial arts later on, but have gravitated more toward more gentler forms and developing the ‘internal’ side of things. At this point in time however, I want to take my current interest in lifting (squats, deadlifts) and upper body, bodyweight exercise as far as I can go. I’m really enjoying it, but know that I need time to develop my strength and increase my muscle, especially in the glutes.
Hi Kerry,
Yes, it’s all interesting – sometimes the limitations are physical and others are about the ones we place in our minds.
Absolutely and the great thing is I’ve really only just started being more serious so it’s quite exciting!
