(modern dive computers are cheap, especially whene cheap quipment is any apparatus or device used during physical activity to enhance the strength or conditioning effects of that exercise by providing either fixed or adjustable amounts of resistance, or to otherwise enhance the experience or outcome of an exercise routine.
Exercise equipment may also include such wearable items as proper footgear, gloves, and hydration packs.It is important to use exercise equipment properly: inappropriate use of equipment can lead to injuries from mild to extreme.The dumbbell, a type of free weight, is a piece of equipment used in weight training. It can be used individually or in pairs, with one in each hand.Young boy holding a discus at the palaestra.

Interior of an Ancient Greek Attic red-figure kylix, 510–500 BC, Louvre Museum, Paris.Dumbbells (halteres) used in athletic games in ancient Greece, National Archaeological Museum, Athens.The forerunner of the dumbbell, halteres, were used in ancient Greece as lifting weights and also as weights in the ancient Greek version of the long jump.[3] A kind of dumbbell was also used in India for more than a millennium, shaped like a club – so it was named Indian club. Despite their common English name implying an Indian origin, the so-called Indian clubs were in fact created in the Near East. Properly referred to as meels, they are first recorded as being used by wrestlers in ancient Persia, Egypt and the Middle East.[citation needed] The practice has continued to the present day, notably in the Varzesh-e Bastan tradition practiced in the zurkaneh of Iran. From Persia, the Mughals brought the meels to South Asia where are still used by pehlwan (wrestlers). British colonists first came across Persian meels in India, and erroneously referred to them as "Indian clubs" despite their Middle Eastern origin. The design of the "Nal", as the equipment was referred to, can be seen as a halfway point between a barbell and a dumbbell. It was generally used in pairs, in workouts by wrestlers, bodybuilders, sports players, and others wishing to increase strength and muscle size"Dumbbells" as a word originated in late Stuart England – referring to equipment simulating the action of a bell rope for the purpose of developing technique, and especially strength, for the purpose of practicing English bellringing (see Change Ringing), but without making a noise (hence dumb). When strongmen started to make their own equipment, they kept the name, even though the shape and form changed. See Oxford dictionary definition.By the early 17th century, the familiar shape of the dumbbell, with two equal weights attached to a handle, had appeared.[citation needed] There are currently three main types of dumbbell:A spinlock adjustable dumbbell.Adjustable dumbbells consist of a metal bar whose centre portion is often engraved with a crosshatch pattern (knurling) to improve grip. Weight disks (plates) are slid onto the outer portions of the dumbbell and secured with clips or collars. Shown to the right is a "spinlock" dumbbell, whose ends are threaded to accept large nuts as collars. Alternatively, a dumbbell may have smooth ends with plates being secured by a sprung collar. Nowadays, many commercially sold dumbbells are available with sophisticated, and easy-to-use methods for weight increments adjustments.
Fixed-weight dumbbells are weights created in a dumbbell shape. Inexpensive varieties consist of cast iron, sometimes coated with rubber or neoprene for comfort, and even cheaper versions consist of a rigid plastic shell that is filled with concrete."Selectorized" dumbbells are adjustable dumbbells whose number of plates (i.e. weight) can be easily changed when resting in the dumbbell stand. This is achieved by adjusting the number of plates that follow the handle when lifted, e.g. by turning a dial or moving a selector pin — rather than manually adding or removing plates. This makes it very easy to change the weight of the dumbbell between exercises, and the stand typically doubles as storage for the additional weights not being used for a particular exercise.The kettlebell or girya (Russian: ги́ря) is a cast-iron or steel weight (resembling a cannonball with a handle) used to perform ballistic exercises that combine cardiovascular, strength and flexibility training. They are also the primary equipment used in the weight lifting sport of girevoy sport. Russian kettlebells are traditionally measured in weight by pood, which (rounded to metric units) is defined as 16 kilograms (35 lb).Kettlebells were developed in Russia in the 1700s, primarily for weighing crops. It is said that these farmers became stronger and found them useful for showing off their strength during festivals. The Soviet army used them as part of their physical training and conditioning programs in the 20th century .[citation needed] They had been used for competition and sports throughout Russia and Europe since the 1940s. Though kettlebells had been in the United States in some form since the 1960s or earlier, Dragon Door Publications and Pavel Tsatsouline developed the first instructor certification program in the USA in 2001.12 kg, 16 kg, and 24 kg kettlebellsUnlike traditional dumbbells, the kettlebell's center of mass is extended beyond the hand, similar to Indian clubs or ishi sashi. This facilitates ballistic and swinging movements.Variants of the kettlebell include bags filled with sand, water, or steel shot.[8] The kettlebell allows for swing movements and release moves with added safety and added grip, wrist, arm and core strengthening. The unique shape of the kettlebell provides the "unstable force" for handling - key for the effectiveness of the kettlebell exercisesBy 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 often involve large numbers of repetitions. 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. In one study, 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".Because of their high repetitions, kettlebell progression should start out slowly to build muscle endurance, support the joints and prevent injury.
The movements used in kettlebell exercise can be dangerous to those who have back or shoulder problems, or a weak core.[10] However, if done properly they can also be very beneficial to health. They offer improved mobility, range of motion and increased strength
