Hello Liffey
The bit that follows your 'PS' piece is a classic example of your ignorance of academic facts..
Biomechanics is arguably the most technically demanding of all the Sports Sciences...check it out. It's a very complex discipline indeed in the technical calculations of loads, angles of velocity etc,leverage dynamics etc.Let alone developing the ability to 'see' it taking place, when someone simply walks past you or turns in a certain way. It takes years.
To say 'there's a lot to know' is a formidable understatement and doesn't cover the intellectual, level of that which there is to know.
The vast majority of the population couldn't grasp Biomechanics either!
I'm a Hons 1st graduate in Sports Science and far from stupid (despite what your opinion might be) and passed out top of my graduation class at University, but Biomech, at advanced level, I freely admit, is way beyond my intellectual capacities. It's such an involved marriage of physiology, mathematics (which are a real nightmare, involving matrix algebra etc) and exercise dynamics. The boss' training alone took 12 years.... considerably more than a doctors training.
All exercise taken freely as in going out for a jog has risks for anyone, but after personal biomech analysis, the risks are almost totally removed.
So......... if you said to someone, that's it's totally possible to have the way you move analysed in depth. The advice you would be given from the results will make you dramatically safer in terms of sprains, strains and overworking whilst also making you less tired. You'll enjoy your jog more as a result and also have less fatigue afterwards. This will result in your fitness improvements happening sooner along with an unconditional guarantee that no hidden biomechanical/musculo-skeletal problems are in progress in any way...they'd say no?....The answer is blatantly obvious, but such a service is ONLY possible from advanced expertise in Biomechanics.
Look up Biomechanics Liffey, before you start comparing it with your college biology and physiology experiences.
When someone is presented with hard clinical facts about something they know virtually nothing about..then ignores them, stating they're 'too dull to read' .....then resumes their opinion with someone who's been involved in it professionally for 20 years (the boss 40).....the behaviour doesn't deserve comment.
There's a very strong aroma indeed about this ( completely regardless of no admission) of someone close, or a relative/friend being a 'personal trainer' or using/have used one!
The statement I made about there being personal trainers and personal trainers is very true. However, despite what you think, it doesn't mean that I'm implying that those working with just a year or a few months/weeks of training should be denied a living.
But it is the much greater levels of knowledge and expertise the 30 odd advanced UK Personal Trainers possess, that renders them the ONLY level of personal trainer that can categorically guarantee results with zero glitches/injury...and that's just one advantage area they have over the field, but definitely the most important.
