Maybe Kattlebell exercises sound unknown, but they are very useful for strength, rehabilitation and health. Basically, they prepare your body for physical activities that you do every day (bending, lifting, climbing and etc.).
The Russian Kettlebell Swing is designed for your back, glutes, legs and shoulders. You must stand straight, with your legs wider than hip distance apart. Grab the handle and hold the Kettlebell in front of you. While slightly bending your knees, move the Kettlebell between your legs, and return it to the starting position. Repeat this 10-15 times, and rest 3 minutes, before the next series.
Two-Arm Kettlebell Swing is used for your shoulders, legs, back and hips. You will have to put the Kettlebell in front of you, bend over and grab the handles. Lift them, while you are still bending over, and move your arms, bending elbows, until the Kettlebells reach your stomach. Repeat this 15 times. You can do this exercise with just one arm, but I recommend two, because for the same time you are exercising twice as much!
The Kettlebell Goblet Squat is good for back, legs and glutes. While you are standing, grab the Kettlebell with your both hands, and hold it close to the chest. Then crunch, until your tights are parallel with the ground. Return to the starting position. Repeat this 15 times.
These were just some of the exercises you can do with Kettlebells. Basically, you can do the same exercises as with weights, and much more. If you are doing these exercises properly, and follow all rules, you will have a great progress. The common mistake when people do exercise for their back is overdoing! This will cause you back pain, and nothing more!
