Noodles and Luv: make sure any lifting you do is whole body. One reason is to avoid muscle imbalances and injuries resulting from the same. Another reason is that it will greatly improve your weight loss. You will be surprised how much weight you will lose simply from lifting as your body will continue to burn calories while you are at rest on your off days as it repairs the damaged muscles. I've got a 42 year old's metabolism and I can keep lean if I simply lift a few times a week and avoid sweets and carbs. As MF said, the basics are: squats, dead lift, lunges, bench press, incline press, military press, lat pulldowns, seated or bent rows, dips, planks and crunches.
Indeed, can't stress this enough.
Awesome! Post every week how much you've lost, and what you did well that week and what you can improve next week. Don't expect to see immediate results, slow and steady is the way to go!
