If the January blues have hit you hard and you desperately want to loose those extra pounds that sprung up over Christmas then there is only one thing for it. Get back to work.

News as come in (to make us all a little happier at being back at work today) that the average commuter burns more than 320 calories a day getting to and from work. Thats a decent M&S sandwich to you and me.

Metro has worked out that during your London commute a typical journey will "see you tackle 16 stairs, walk for 12 minutes and stand for a further ten."

Virgin Active's advice to those that want to get super toned on their commutes is to clench your but cheeks on ever stair step and yes, that means walking not standing on the escalators.
