These are high quality Kettlebells with a nice wide handle and thick grip for comfort in your swings. The Neoprene cover helps to protect your floor and the Kettlebell if dropped in group fitness and personal training settings. Working out with kettlebells will sculpt and tone the entire body. Lifting and controlling a kettlebell forces the entire body, specifically the core, to contract as a group and builds both strength and stability at the same time. Kettlebell workouts are a great option for getting a whole body workout in a short time.
The kettlebell is a cast-iron or cast steel ball with a handle attached to the top (resembling a cannonball with a handle). It is used to perform many types of exercises, including but not limited to ballistic exercises that combine cardiovascular, strength and flexibility training. The are also the primary equipment used in the weight lifting sport of kettlebell lifting.
Unlike traditional dumbbells, a kettlebell's center of mass is extended beyond the hand, similar to Indian clubs or ishi sashi. This facilitates ballistic and swinging movements. The kettlebell allows for swing movements and release moves with added safety and added grip, wrist, arm and core strengthening. The weight of a kettlebell is not distributed evenly. Thus, the unique shape of a kettlebell provides the "unstable force" for handling - key for the effectiveness of the kettlebell exercises.
By their nature, typical kettlebell exercises build strength and endurance, particularly in the lower back, legs, and shoulders, and increase grip strength. The basic movements, such as the swing, snatch, and the clean and jerk, engage the entire body at once, and in a way that mimics real world activities such as shoveling or farm work.
Unlike the exercises with dumbbells or barbells, kettlebell exercises involve large numbers of repetitions in the sport, and can also involve large reps in normal training. Kettlebell exercises are in their nature holistic; therefore they work several muscles simultaneously and may be repeated continuously for several minutes or with short breaks. This combination makes the exercise partially aerobic and more similar to high-intensity interval training rather than to traditional weight lifting. Study results of 2010 show, kettlebell enthusiasts performing a 20-minute snatch workout were measured to burn, on average, 13.6 calories/minute aerobically and 6.6 calories/minute anaerobically during the entire workout- "equivalent to running a 6-minute mile pace". When training with high repetitions, kettlebell progression should start out slowly to build muscle endurance, support the joints and prevent injury.
Like movements performed with any exercise tool, they can be dangerous to those who have back or should problems, or a weak core, when performed without proper education and progression. However, if done properly, then are very beneficial to health. They can offer improved mobility, range of motion, agility, cardio vascular endurance, mental toughness and increased strength.
