I exercise about 40 minutes a day, and I'll run one day and do circuit training the next day. I live in an area where there are brilliant hills and mountains, so I get a good hill run with my dog. At home, I'll do the circuit training with old weights, along with pull-ups in the trees and that sort of stuff.

A wise man knows; learn from others, never get complacent and know where the classic old dangers come from.

I train five days a week hard - but it is short and sharp - 30 to 40 minutes of functional and pretty dynamic body-strength circuits, then I do a good yoga session on the sixth day, then I rest.

Weather can kill you so fast. The first priority of survival is getting protection from the extreme weather.
