Kettlebells - The Emperors New Clothes??

Unfortunately the fitness world seems to jump from fad to fad thanks to the massive sums of money spent by the unwise public year upon year. From diet programs that claim to lose a stone a week to pieces of equipment that soon are found cluttering up peoples sheds and garages worldwide.
Anything that is marketed as quick or easy is jumped on- take the vibration plate for example- an excellent rehabilitating tool when used correctly but for weight loss just too ineffective to produce any real results. Or for instance the horrendous ab cradle.Designed to make exercise once again 'easier' by easing the load on the neck- one fundamental flaw though- it creates a huge imbalance in the flexor chain with the abdominals isolated these grow stronger, whilst the neck flexors atrophy (as the head is supported) leading to postural imbalances and also increased risk of injury- but hey I'm sure that 1000 crunch will help you on your way to a six pack- what rot on all levels!
Kettlebells have seen a massive rise on the fitness scene with many a unqualified and inexperienced trainer jumping on the band waggon and telling their clients that these are the last word in fitness.
As many of you know I am a keen advocate of all things kettlebells and they are by far my favourite fitness tool to work with. They promote excellent reactive core stability, flexibility, cardiovascular fitness endurance and to a certain degree strength- but- and this is a BIG but, they should not be used as a stand alone tool for several groups of people.
Firstly for hypertrophy. For muscle gain simply don't bother- an untrained individual may experience some muscle growth with kettlebells but an intermediate to advanced lifter should not switch to sole kettlebell use- the same way you wouldn't limit yourself to solely machines,dumbbells or barbells. For certain exercises yes they do provide an extra pull towards the starting position - like a cable- think flys and curls, but for many motions they are simply impractical with the weight needed eg a bench press- the bells would have to be so large that the wrists would be placed in excessive extension and why not simply use a standard lift which will be easier to manipluate?
Some people advocate them as a stand alone tool for athletes- again I say no. Athletes within periodised programs during their max strength and conversion to power stages need to subject their bodies to massive poundages on the barbell that simply can not be achieved with a kettlebell. The instability factor of having two independant bells also lowers the poundage being used and so becomes ineffective. Kettlebels as a light supplement to standard training can definitely have a place in an athletes current routine to improve shoulder and core stability though but it should be just that a supplement.
So who are kettlebells for? They are an excellent supplement to most peoples training - and for a few an excellent stand alone tool.
But those who use them as a stand alone tool should really only be concerned with an improvement in general fitness.They should not be aiming for anything particulary specific as you will not reach maximal levels of strength or endurance or power soley with kettlebells- the heavy load of the barbell is required.
They are also an excellent addition to any athletes cardio vascular conditioning, mainly though in anaerobic/aerobic cross over zone- such as many fighters and grapllers work in.
I train 3 times a week with the bells mainly to improve my grappling fitness- for which they are excellent. However I still put in 2-3 really heavy compound lifting sessions under the bar to keep my strength levels near their peak which I find works best.So don't see kettlebells as another fad- they are not; however see them in the context they are meant to be- as a supplement to a well planned diverse routine.
