Weight training again

I've began weight training (with my 4-lb weights) yesterday. The last time I regularly did weight training was in Singapore nearly ten years ago. (I then had to improvise with a mop pole and empty 1-liter milk containers filled with water to make a 6-kilo dumbell). Joel urged me last Saturday to do load-bearing exercises to strengthen my bones. He thinks it's unusual for someone my age to have fractured my olecranon after simply slipping on a wet slidewalk and landing on my elbow.
