What is a kettlebell?
A kettlebell is a cast iron weight that is shaped like a bowling ball with a thick suitcase-style handle. Kettlebells range in weight from 4kg (9 lbs) to 40kg (88 lbs). Because of their imbalanced shape, they are lopsided and harder to hold. This is a big difference from dumbbells and barbells which are completely balanced and symmetrical. This KB imbalance requires the use of more stabilizing muscles and generates a different strength curve than conventional weights. These physics can be demonstrated by performing the most basic of lifts.
How did kettlebells come into existence?
Kettlebells first appeared in Russia over 100 years ago. Originally kettlebells were used in fairs and markets to balance scales when weighing heavy objects. The Russian military began using them within their training regime because they demand an overhaul of all of the body’s energy systems simultaneously.

Variety IF YOU MUST KETTLEBELL EXERCISES
Tips for performing the Kettlebell Press: -Lock out your knees and contract the legs and buttocks. -Hold the empty arm out to the side for more balance. -Try to touch your ear with your bicep as you lock out. 

Kettlebell Snatch is one the best exercises you can do.
Virtually all muscles are involved, weak links are revealed and addressed.

Following tips will instantly improve your kettlebell snatching technique:
The foundation kettlebell exercise is the kettlebell swing. The swing can be done with 1 or 2 hands. It involves hiking the kettlebell between your legs before using your hips and posterior chain to propel the kettlebell forward and up in a circular swing movement before it drops under control back between your legs. The following great benefits can be gained by training with kettlebell swings.
1). Kettlebells are highly efficient and allow you to do fitness and weight training in one workout at the same time.
2). Swings develop the important posterior chain muscles of the body such as the hamstrings, glutes, core and back. These muscles are often overlooked with traditional weight training but they are crucial for a large number of sports as these muscles are heavily involved in sprinting, jumping and tackling movements.
3). A kettlebell swing is a perfect choice of exercise for tabata training. This very short but intense style of training is ideal for kettlebell swings as they hit a lot of muscle at one time and get the heart rate soaring. Although Tabata training only involves work periods of 20 seconds with 10seconds of rest it is very brutal but very effective.
4). Swings work the abs and strengthen the core muscles as they provide a stable platform for other muscles to pull from. Traditional crunches are useless and do nothing for you, hit your abs with functional abdominal training that actually has benefit in the real world.
5). A key benefit of kettlebell swings is that they train all parts of the back from the lower back all the way to traps. They train all the muscles together giving you a great functional workout
6). High rep swings also develop back endurance which Professor Stuart McGill a leading spine/back expert considers has a very positive effect on the reduction of back injuries.
7). Swings are a fantastic conditioner and body fat burner. More and more studies are concluding that greater body fat burning occurs when training is performed at higher intensity levels rather than long slow endurance type training.
SWING WORKOUT
SWINGS
Swings are your bread and butter kettlebell movement. No matter how long you have trained with kettlebells, this should always be your first movement. The two handed kettlebell swing should also be your introductory movement when first teaching your athletes. The movement starts with both hands on one kettlebell. The kettlebell is placed on the ground, between the legs. With a straight back and flexed stomach muscles, take a quick breath. Breathing in at the bottom with a flexed stomach will help to brace the back. Forcefully stand up and explode with a good hip snap. The momentum from the legs exploding and the hips snapping up will make the kettlebell swing in front of you. Exhale when you reach the top of the movement. The arms do nothing but grip the kettlebell. The legs are what move the kettlebell, not the arms. The kettlebell will then fall back between the athletes legs. The athlete will need to catch the kettlebell using their hips and hamstrings, and then repeat the movement. This is a ballistic movement and is done quickly. You should stay within the 8-12 rep range and use a heavy kettlebell. Remember, the kettlebell needs to be heavy enough to really feel the movement. You can drive a fence post into the ground with a small hammer, but wouldn’t a sledge hammer work better? You can tweak the movement once the basics are taught
There are no rules, per se, but here are some suggested guidelines for the 10,000 KB swing challenge:
