Kettlebells are great tools to use to build strength in your body, as long as you know how to use them properly. They are not cheap or easy to store if you are short on space. The Ironmaster Quick-Lock is a kettlebell that can be adjusted from 22.5 – 57.5 lbs. It has an all metal construction and accepts Quick-Lock Dumbbell weight plates. The handle is big enough for two handed use, but you can also use it with one hand. If you already have the weights, you can simply get the handle, which weighs 22.5 lbs.
