"At some point it dawns on the ageing warrior that he’s as supple as a rock.
"A lot of guys will start going to yoga classes, but I think flexibility training is best done solo so you can target your specific issues.
"It’s pretty simple: stretch whatever’s tight. If you’ve been working at a desk for 20 years, start with your hip flexors."
