I'm ok with the eating healthily bit, but I find it difficult fitting exercise into my day. By the time I get home from work all I want to do is relax a bit. I did used to go to the gym at lunchtime, but where I work now there isn't one near and I get a shorter lunch break. I do try and get out for a 20 minute walk every lunch time, and I do try to do something when I get home, but it is hard to squeeze everything in. Any tips?
