Good work bud. I'm doing the same at Hearts, lost 4.9kg so far, loads more to go though but a good start. I also find weekends difficult, with junk food and less exercise.
I have also joined the gym and got a PT to make up a programme for me to follow with a mixture of cardio and weights and it seems to be working so far, although it's difficult to get to the gym more than 1-2 times a week just now.
