Weight machines:
1. Weight machines are easy to learn and use.
2. There are some exercises you can do with a machine that you can't do with a dumbbell. For instance, cable rows would be difficult to replicate with free weights. You could do bent over dumbbell rows, but they won't be quite the same.
Free weights:
1. Free-weight training requires balance and coordination, and so if you are involved in a sport that requires balance, or you just need balance training, then free-weight training might be more effective.
2. Free-weight training may recruit more muscles than a machine because you have to stabilize your body when you lift a dumbbell, whereas the weight machine supports you. For example, a biceps curls is going to feel more natural and use more muscles in your torso (to support the weight) than if you did a seated biceps curl in a machine where the machine does some of the work and you can lean against it for leverage.
