The gym is not for everyone who wants to get buff — some people prefer to set up something they can do in the privacy of their own homes, but space can be a big problem when you need to store multiple weights and racks. PowerBlock products help solve that problem. Instead of having to switch dumbbells every time you need a new size, PowerBlock dumbbells allow you to easily change how much they weigh by simply moving a selector pin. The company offers twelve different sets of dumbbells, ranging from the basic U-20 Set that allows you to adjust between 2.5 and 20 pounds to the Heavy Weight 175 Set that adjusts between 10 and 175 pounds. Expansion kits are also available, as are barbell and kettlebell style PowerBlock products. If you want to keep your home gym organized, you can choose from a number of stands that hold your dumbbells. Several different types and sizes are available, including the PowerStation which allows you to attach your TV, so you can watch while you workout. With a vast inventory available on eBay, you are sure to find the dumbbell set that meets your workout needs.
