I've just completed Day 1 of Week 1 so I am really new to this! I walk a lot and fairly quickly doing 4 x 15 mins - home to station; station to work and the same in reverse on my way home, plus I go out for a walk at lunch time every day but I'm overweight and struggling to get my weight down. I did all of the runs so day 1 went well. I'm using a treadmill at home because I know I won't go out and do it (I've been planning to for about 12 months and haven't...)
But I've started and that can't be a bad thing!
