I'm no fitness expert, but I do use just light hand weights (is that the "politically correct" term for dumbbells, these days?
) to keep toned, but I'm not into any serious weight training. I walk with the kind of hand weights that have the straps on them, and I do a few exercises with my other weights, but I'm more into yoga and Pilates, plus I've added some stretching exercises that my physical therapist taught me, and have recently purchased an exercise ball. I also do some bench stepping, and of course, my bellydance class.
