As we have an extra day in the calendar this year Nike felt that rather than go for a drink to celebrate, or propose to my boyfriend over a candlelit dinner in keeping with tradition, I should do a workout. 'Fine, I'm in' I said, much to the relief (I'm sure) of my boyfriend.

I'm afraid of heights, which is never really an issue when it comes to aerobics, but tonight's class is going to be held in a pod on the London Eye.

I've been up there twice, the first time I didn't look up from my seat. Second time I tentatively managed to stand for all of five minutes before resuming the eyes closed seated position from the time before. So for me, the extra day is less about the working out and more about conquering a fear.

How are you going to make your extra day count?
