If you get access to a gym, I think you will notice results with strength training. If not, you can still do a lot of things at home. I don't belong to a gym. I do my resistance training at home with resistance bands (mostly with handles and door attachments) that can be purchased at most fitness equipment stores. They come with instructions and there is lots of info on the web to build a good routine. I also just do body weight exercises, like crunches, push-ups, leg lifts, squats, lunges, etc. I do a thirty minute full body workout 3X a week -- nothing crazy, but I have really nice abs!

Do not be surprised, however, that it takes around six weeks for noticeable results -- lean muscle mass grows slowly, but as you add it, you will look different. Your clothes will fit better. You will get stronger and you will, hopefully, raise your metabolism a bit as muscle tissue is "active tissue" and requires more calories to function. You may even find that you can eat more calories and still lose weight.
