That feeling when you're so cold you'd give anything to be warm - I've had it before, literally huddled around a candle flame on an ice sheet.
Bear GryllsI 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.
