Im 5ft 8. Weigh 13st 11. Want to reduce this to 10st 5. Over 3 stone to go. I work from home and am a lone parent. I drop son at nursery at 8, start work at 9, between 8 and 9 I'm having my breakfast and showering as I prefer to do this when my son isn't in the house. He's only 4 and it means I don't have to leave him unsupervised (he won't sit in the bathroom whilst I shower). I have so little time but have started walking on my lunchbreak. Very brisk 45 minute walks every day. Only been doing it for 3 days but loving it so far. I've been hitting my 10k steps by making sure I get up every 30 mins and also taking my son to the park at the end of the day and running around with him. If I combine with a healthy diet, is this enough to get fitter, build a little muscle tone and lose weight? Not trying to look like a super model, just tired of feeling so unhealthy.
