To break up the bmi argument.....
Guy at work,,older than me in late 40s, fairly fit, no smoking and only drinks a few ports was talking to me on Monday at work.
Said his back has been really sore and his BIL made him an appointment with a chiropractic...fair enough.
We were then chatting away and he asked me how I was going with my routine id started etc.
I said it's going good, apart from a crap pain right in the centre of my butt check that feels like the hip joint it's been good.
I said ive been doing some reading up on kettle bells for the last fortnight or so and will get myself into that maybe twice a week and I'm reading a pdf on it now
He then proceeded to say he was doing some kettle work on a sunday in the gym at work.
Cool, what are you doing i asked
He said he was bending over and picking up the kettle and then bending down and putting it back down, two sets of ten reps
Using a 20kg kettle....having never done it before, never read anything before except look at the pic on the gym wall
I asked him if he knew why his back was stuffed.....said he wasn't sure

We parted ways and he went back to what he was doing.....picking up 9 kilo cartons from the pallet on the floor UP to a pallet at waist high, no pivoting of feet no proper tech no idea basically.
I mean we all do something wrong in form now and then but bloody hell, you're picking up a 20kg kettle bell and putting it down having never done it before and don't follow manual handling practices all night while at work.....and you wonder why your backs killing you???
Not a proper rant about gym etiquette but just makes me shake my head sometimes
I mean I'm a newbie to all this but the reasons why the bloke had a crook back were staring him in the face and he couldn't put 2 and 2 together
