Kettlebells

The Kettlebell or girya is a cast iron weight looking somewhat like a cannonball with a handle. Many companies produce their own brands of kettlebells and kettlebell exercise programs. Some modern kettlebells feature adjustable weights.

While today, there are sizes that range from 5lbs to 70lbs, the traditional Russian kettlebell is usually one which weighs 1 Pood (roughly 16kg / 35lbs).

Unlike traditional dumbbells, the kettlebell's center of mass is extended beyond the hand, similar to a Clubbell's. This allows for swing movements not possible with traditional dumbbells. Because more muscle groups are utilized in the swinging and movement of a kettlebell than during the lifting of dumbbells, a kettlebell workout is said to be more effective, and yields better results in less time.

Because the center of mass on a kettlebell "swings", micro-muscles are needed to balance a kettlebell, more so than a dumbbell. The existence of a handle allows for "release moves" which are not available to a dumbbell.

Healthcare Background

Health care, or healthcare, is the treatment and management of illness, and the preservation of health through services offered by the medical, dental, complementary and alternative medicine, pharmaceutical, clinical sciences (in vitro diagnostics), nursing, and allied health professions. Health care embraces all the goods and services designed to promote health, including “preventive, curative and palliative interventions, whether directed to individuals or to populations”. The definition of health care is continuously evolving and varies significantly between different cultures.

Before the term health care became popular, English-speakers referred to medicine or to the health sector and spoke of the treatment and prevention of illness and disease. The social and political issue of access to healthcare in the US has led to public debate and confusing use of terms such as "health care" (medical management of illness or disease), health insurance (reimbursement of health care costs), and the public health (the collective state and range of health in a population).
