Professor Tipton explains: ‘If you go out for a run, most people are producing 500 watts to a kilowatt of heat, which is a lot of heat. ‘The best forms of training in the winter is continuous exercise where you’re producing plenty of heat. For example, if you ran for five minutes and walked for five minutes, you would get very cold, very quickly because you would stop producing heat.
