Are we supposed to be doing weight training the same day as cardio? Or should it be weights one day and cardio the next day??

I was told years ago to do cardio to get your heart rate up and body warmed up for strength training, but I guess times have changed. Here's a link with advice on which way to go.

Thanks for the link it was a big help

If you're doing strength training to build up endurance and lose weight, it's 6 in one hand and half a dozen in the other (it really doesn't matter). I always split mine, but that's because I don't want to do cardio before and lose any strength or stamina for my leg workouts, and I don't want to kill the muscle Fiber AFTER a huge leg day and go catabolic. If you're doing legs, you can do a light warm up on on the treadmill or elliptical, no worries.

If you're tight on time, check out complexes. They're sort of a crossfit inspired workout. I've used them for weight loss and cutting for meets in the past.
