I forgot to add a few things. If you are trying to lose weight then you need to focus most of your workouts on being high speed. I mean never stopping and doin alot of high reps on every machine. Then follow it with some precor machine or some treadmill. At least 20 mins on either one of those. Anything under 20 mins is a waste. And alot of people do not agree with me but the only real true enemy in food is sugar. Everything else is ok to eat. Sugar is what keeps the pounds on and adds them. I still believe you need to eat a high protein diet but do not worry to much on cutting carbs and fats. You still need both of them for energy and to gain muscle. Now I am not saying go eat a loaf of bread every night either but you just do not have to go insane trying to stay away from them. Alittle of them is not goin to hurt. Alot will but you need to focus on staying away from sugars.
I have been all over the weight scale, from 170 for bulking and building muscle size down to 155 for competing. You must be getting in at least 1 gallon of water a day if not more. At least 1.5-2 times your weight in protein. At least 6 meals a day. You gotta keep your metabolism goin and keep it as high as possible. So with that said, do not worry about your working out so much as your diet. Diet is first, then comes the workout.
