Who isn't looking for a quick and easy way to get toned arms? That's just what the Shake Weight ($20) promises — in just six minutes a day. Weighing in at just 2.5 pounds, it supposedly tones your upper body faster than regular dumbbells. I'm not buying it though. I'm sticking with regular hand weights since they're effective and don't require you to gyrate your body up and down. Dumbbells are also fairly inexpensive, easy to use, and offer more variety since they come in a range of weights. Another plus is that you can use dumbbells to tone just about every part of your body, depending on how you use them. The Shake Weight only works your upper body (if it works it at all).
