I have a few questions for anyone who might know. I mainly need to loose weight BUT I prefer lifting weights over cardio- even thought I have started doing cardio 3 times a week for 30 minutes. I know that lifting weight will make you gain muscle which helps to burn fat. My question is after 3 months of weights I have lost only two pounds. Does that sound too low? I know I need to up my cardio but I feel like I just cancelling it out with the weights. So should I stop lifting weights all together until I have reached my goal?
Advise please....

No, no, no.... keep with the weights. The thing you have to remember is that in the beginning, when you start weight training *weight* loss may seem slow, but *fat* loss will probably be consistent. When you add some lean muscle to your body, your weight may not change or even go up, but you will see a leaner body. You are on the right track. Keep doing weights AND cardio and make sure that your diet is in check. All the exercise in the world won't help if you aren't eating right. Now that you're past the initial muscle building phase, you *should* start to see quicker, consistent fat loss - if diet is good and you may want to increase cardio.
How often do you do weight training?

Three times a week. I consulted a trainer at the gym and she put me on a light circuit mostly legs and arms. She said to put a lighter weight and do more reps to burn more fat. I have been walking 10 minutes then about 40 min circuit and then 20-30 minutes of walking again. Does that sound about right to you guys???

Walking isn't really intense enough if you want to see fat loss. Try jogging or using an eliptical machine. You really need to get your heart rate up and walking generally doesn't quite get you there.
I'd also recommend heavier weights. The trainer you consulted is passing on bad information (basically the least efficient way to strength train). High rep ends up being pretty much like more cardio. If you want lean muscle that will increase your metabolism, you need to work heavier, in the 10-12 rep range. It will make a huge difference.

I busted my knee up in a car accident so I can't do too much. That's how I ended up gaining so much. Sitting on my butt!!!
Thanks for the advice!!!
