I usually do some casual boxing routine at home. I have a boxing bag setup with some weights.
I have also found that I am cutting back on the booze through the week. Hoping to get to only a drink through the week and also I have stopped snacking and choosing the water or fruit option.

I am currently reading the book "Presto" by Penn Jillette (of Penn and Teller fame). He goes on that Potato for 2 weeks diet that Kevin Smith did after his heart attack. It's an interesting read that he also talks about their performances in Vegas for their magic show.
