Agreed with REYNINGSUNSHINE 1000% percent.
You can lose weight with 3 hours a week, or 6 hours; in fact, you have to eat more when you work out more, so the goal is to work out to what you can stick with, and adjust your eating to that.
You DO need to add strength training; with just cardio, as much as 30% of your weight loss can come from lean muscle mass. A program that doesn't include some kind of strength training is an incomplete one at best. :)
You don't get "man arms" from strength training. Honestly, if you're a women, you don't have the testosterone to bulk up: www.sparkpeople.com/resource/fitness_artic
As for your weight gain, it's possible that you didn't burn enough to compensate for overeating. Adding things up in your head is a guaranteed way to overeat. :) We actually really stink at eyeballing things, and I'm betting dollars to donuts you're probably eating more than you think you are. You need to be tracking accurately, weighing and measuring, and not relying on your head to keep track. Write it down keeps you accountable (and here on SP, gets you Sparkpoints!)
Intense exercise can also trigger temporary water weight gain. This is normal, and will eventually balance out: www.sparkpeople.com/community/ask_the_expe
Basically, our bodies are not calculators, and even when all the math adds up perfectly (which it almost never does anyway) there are still other variables at play.
