Hiya,
Pre LT I never did any exercise, but since losing the weight have a lot of very problem areas that need fixing, and I also know it helps with the weight loss. So I have now forced myself into a routine, 10 min on vibro plate, 60 x sit ups, 30 x press ups and the exercise bike every day. Try to something extra at weekend such as an exercise dvd, walking or swimming. Would love to do more or join the gym, as I am really quite enjoying it, never believed exercise gave you the feel good factor, but it does! Just haven't got enough hours in the day to fit it in.
Your doing well with yours, anything is better than nothing, carry on the good work
