In the winter I'm less active at work, eat more and lift heavier. It's only natural to go up in weight. I don't really do any cardio. Usually starting in February I'll start running to drop some weight and once work starts it's easy to keep it off.
I've for sure lost some muscle mass and strength but I don't really care. I feel better at 175 than 193. I used to lift heavy all year long but I'm not trying to get any bigger so I basically lift to maintain at this point.
