Dumbbells and Dumbbell sets

Dumbbells are a well-known piece of fitness equipment and there are many different exercises that can be done with a dumbbell.  Though often associated with upper body exercises, holding dumbbells can be a great way of increasing the difficulty of lower body exercises such as squats or lunges.  Essentially, a dumbbell is a very versatile piece of fitness equipment and if you really want to tone your body then you'll probably want to have some dumbbells lying around at home.  Progression is an important part of fitness training, so you may want to consider dumbbell sets, which mean you have a range of weights available both for different exercises and for increasing the intensity once the weight you've been using starts to feel a bit light.
