Today, a weekend, about 1 1/2 hrs. Did upper body weights, kickboxing for cardio, and an ab work out. Tomorrow will do lower body weights and cardio if I feel energetic. During the week, about 50 minutes. Typically do upper body weights, lower body weight, or cardio (kickboxing or, in warm weather a run), on separate days. Some days I do nothing if busy or tired. I also find that, over time, I tend to want to do more.
