i really want to start weight training.
i am reading that weight training is an important part of weight loss.
it's also supposed to be good in helping preventing osteoporosis (which runs in my family).
i can't afford a trainer, so i'm hoping there's a really good dvd out there that will guide me.

Start with bodyweight exercises! Here are a bunch of how to videos: http://nerdfitness.com/blog/how-to-videos/

You can also search on youtube.

thanks!!
