Kettlebells are a classic Russian strength implement that have enjoyed a rush of fame in the past few years. Unlike conventional barbells and dumbbells, kettlebells are projected to be swung explosively and are used to develop power as well as conditioning.

Most common types of kettlebells are:
- Lighter vinyl coated
- Cast Iron
- Pro grade steel
- Adjustable
Vinyl Coated Kettlebells
These kettlebells can be found on advertisement, sporting good stores and online. These are regularly associated with fat burning routines designed for lighter weight higher rep workouts targeting women starting out with kettlebells. There is nothing wrong what so ever with these kettlebells.

These are cast iron and vinyl or rubber coated, building them a little less rough on the hands and more visually appealing to some. If you are a beginner, looking forward to trying kettlebells and going to use basic swings and movements, this is a completely sensible place to start.
Cast Iron Kettlebells
The normal black iron kettlebell you see is the cast iron bell. This is a huge all purpose kettlebell and can work just fine for men and women looking for cardio and muscular endurance. They come in all sizes ranging from 8 Kilos to 48 kilos. While the cast iron kettlebell is virtually permanent, cast iron is somewhat breakable and could crack if dropped hard enough on hard surfaces or dropped over and over.

Under normal conditions, working out at home you would tough pressed to damage an iron kettlebell. One of the main drawbacks to the cast iron kettlebell is the different sizes and handles. This will most likely never be a problem if you are only doing the one or two hand swing with one kettlebell. These swings alone are effectual fat loss kettlebell exercises.
Different sizes for realistic purposes means, a lighter kettlebell is smaller in size than a heavier bell and the handle is normally thinner at lighter weights and gets really thick at heavier weights. Where this affects you most is in the exercises when you are using two kettlebells at once, such as cleans, snatch, presses etc.. The reason this is a disadvantage will become apparent the first time you do these exercises and change weights.
Pro Grade Kettle bells
The pro grade kettlebells are top of the line. The main difference with pro grade bells is reliability in size and handle. The 8 kilo kettlebell is the same size as the 48 kilo bell. The handles are the same thickness and the same distance from the weight of the bell. In theory, if you pick up a pair of kettlebells and perform a movement, then move to a heavier weight, the only thing changing is the weight of the bell.

Adjustable Kettlebells
There are many different types of adjustable kettlebells. These can be found in the pattern of the cast iron bells and in the pro grade kettlebells. Others look like a stack of rounded weights, which can be familiar with the turn of a dial. Some are hollow and have a large screw in the bottom. This allows the user to place their own payload into the bell.
The plus to this method is the total control over the weight you add. The disadvantage could be the dynamic shift of the weight you place inside the hollow bell. It would be advisable to try out the adjustable kettlebells to get a feel for the different shapes. You may find one or more very tight to work with. The more square shape adjustable kettlebells could be very uncomfortable in cleans and snatches.
