The BBC's Horizon (28 Feb 2012) seemed to confirm for me what I'd always suspected - at least for me (minimal times, hi-value exercise seems to do as much 'good' as any amount of puffing and preening at the 48 million Gyms this country appears to have).
We're lucky here in Dorset, it seems unthinkable to use a walking-machine, indoors, in a Gym - having driven there, and paid monthly to walk. With over 7 miles of beach it all seems a bit silly.
S'Funny, we have more Gyms than ever in the UK, and more Obesity than ever. I suppose it is more likely that we do have more toned, muscled inhabitants than we ever used to, but to be fair - how much of this is a product of a Body Concious mentality - rather then fitness for Health?
In the same way, I know in my heart we're probably not too far away from the results of some 'Study' - and we'll be informed (or more possibly, we won't) that - well, actually, five-a-day is a bit wierd . . . hardly necessary, and . . . well, the proof was never really there.
Now, where did I leave those Barbells?
