I do a 5 day split. My favorite is without a doubt chest day and back comes second. Leg day is the worst- period. Cardio is meh. Once you get used to it, it's OK- good for the heart.
I workout at home but I still rarely do that, I prefer to swim. I workout about 2 times a week and on top of that I swim a lot and do a majority of the yardwork. But, when I do workout, my favorite thing to do is benchpress.
