Bob, you should definitely add some sort of resistance training to your workouts. There's really no need to workout twice a day either. Just when you do cardio, try it out on a empty stomach first thing in the morning 3-4 days a week tops. Do something high intensity like the stairmaster, or running, or intervals. This keeps your cardio fun and challenging and keeps it less than 25min workouts. It's great for burning fat too, and then wait about 45min after the cardio to have your protein shake. Doing the cardio first thing also ramps up your metabolism for the rest of the day as well.

As far as resistance training, make sure to do some sort of it 3 days a week, it's great for building muscle, which in turn burns calories, unlike fat. Just gaining 5lbs of muscle can help make tremendous strides towards dropping fat. Even though people often times don't *lose* weight with lifting weights/gaining muscle, they look *far* better and look slimmer than the scale says. Shoot most people are in shock when I tell them I weigh 225.
