For those out there who regularly train for fitness - what do you do for your cardio? I'm working on my new years resolution for the third year in a row to loose weight. I've made dietary changes, but I need to get on a more regular work out schedule. I don't frequently have a lot of time during the week to do so between work and family - so I want and need to make the most of my workout time. I've got a weight bench, which is great for working the arms. I want to get going on a good cardio workout though, since that's where a lot of the weight loss and agility is going to come from.
