To get started on strength training, they advise you to start out with 3 and 5 lb weights. You'll be amazed on how strong you will get if you do this about 2x a week. They do recommend strength training 2x a week because it helps build bone density in prevention of osteoperosis, really speeds up the metabolism, and just helps you look better. You may think your going to bulk up, but really, your actually burning fat and toning up. They say the more muscle you have, the more calories you'll burn even at rest! You'll be suprised at how much weight training can be enjoyable after you get strong. My first video tape for weight training was "Lift Weights to Lose Weight" by Kathy Smith, and she just recently came out with LWTLW #2, a second one. She's great. I still use the second one and also videos by the Firm. You have to start off light, but there are great benefits to weight training. Hope this helps!
