I am a fairly unfit single mum and I work full time so my chances to get exercise are extremely limited. I commute into London every day for work and don't have the time/money to join a gym at lunchtime. I've started getting up a little earlier most days to do some jogging, muscle exercises and yoga on my Wii Fit (old version) mainly so I can generate some energy to keep up with my 3 year old DD but I'd also like to aim for something such as doing the Race for Life; I'm just worried that the difference between jogging on the spot and actually running outside is too great! Have any of you done something like this? I need some advice and inspiration please.
