Exercise equipment 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.
Strength-training equipment
A broad range of different types of exercise equipment are available, including
Free weights such as dumbbells, kettle bells, barbells
Resistance bands
Weight machines
Flexion machines
Pull-up bars
When strength training, not only should the weights used be considered, but also the space available, one's diet, and clothing should also be taken into account.
is a common type of strength training for developing the strength and size of skeletal muscles. It uses the weight force of gravity (in the form of weighted bars, dumbbells or weight stacks) to oppose the force generated by muscle through concentric or eccentric contraction. Weight training uses a variety of specialized equipment to target specific muscle groups and types of movement.
Sports where strength training is central are bodybuilding, weightlifting, powerlifting, and strongman, Highland games, shotput, discus throw, and javelin throw. Many other sports use strength training as part of their training regimen, notably; mixed martial arts, American football, wrestling, rugby football, track and field, rowing, lacrosse, basketball, baseball and hockey. Strength training for other sports and physical activities is becoming increasingly popular.
A treadmill is device for walking or running while staying in the same place. Treadmills were introduced before the development of powered machines, to harness the power of animals or humans to do work, often a type of mill that was operated by a person or animal treading steps of a treadwheel to grind grain. In later times treadmills were used as punishment devices for people sentenced to hard labour in prisons. The terms treadmill and treadwheel were used interchangeably for the power and punishment mechanisms.
More recently treadmills are not used to harness power, but as exercise machines for running or walking in one place. Rather than the user powering the mill, the machine provides a moving platform with a wide conveyor belt driven by an electric motor or a flywheel. The belt moves to the rear requiring the user to walk or run at a speed matching that of the belt. The rate at which the belt moves is the rate of walking or running. Thus, the speed of running may be controlled and measured. The more expensive, heavy-duty versions are motor-driven (usually by an electric motor). The simpler, lighter, and less expensive versions passively resist the motion, moving only when walkers push the belt with their feet. The latter are known as manual treadmills.
The first consumer treadmill for home use was developed by William Staub, a mechanical engineer.[1] Staub developed his treadmill after reading the 1968 book, Aerobics, by Dr. Kenneth H. Cooper.[1] Cooper's book noted that individuals who ran for eight minutes four-to-five times a week would be in better physical condition.[1] Staub noticed that there were no affordable household treadmills at the time and decided to develop a treadmill for his own use during the late 1960s.[1] He called his first treadmill the PaceMaster 600.[1] Once finished, Staub sent his prototype treadmill to Cooper, who found the machine's first customers, which included sellers of fitness equipment.
Staub began producing the first home treadmills at his plant in Clifton, New Jersey, before moving production to Little Falls, New Jerse
Treadmills for power

Treadmills as power sources originated in antiquity.These ancient machines came in three major designs.The first was to have a horizontal bar jutting out of a vertical shaft. It rotated around a vertical axis, driven by an ox or other animal walking in a circle pushing the bar. Even humans were used to power them. The second design was a vertical wheel that was powered through climbing in place instead of walking in circles. This is similar to what we know today as the hamster wheel. The third design also required climbing but used a sloped, moving platform instead.
Treadmills as muscle powered engines originated roughly 4,000 years ago.Their primary use was to lift buckets of water. This same technology was later adapted to create rotary grain mills and the treadwheel crane. It was also used to pump water and power dough-kneading machines and bellows.
Treadmills for punishment

Treadmills were invented by In 1818 by an English engineer named Sir William Cubitt, son of a miller. Noting idle prisoners Bury St Edmunds gaol, he proposed using their muscle power to both cure their idleness and produce useful work.
Cubitt's treadmills for punishment usually rotated around a horizontal axis, requiring the user to step upwards, like walking up an endless staircase. Those punished walked around the outside the wheel holding a horizontal handrail for stability. Earlier treadwheels include either horizontal or inclined-axis devices designed for a single user as well as a horizontal-axis design with the user inside and using the shaft as a handrail, in a manner similar to the familiar toys for small pet animals such as hamsters.
They remained in use until the second half of the 19th century; they were like twenty-foot long paddle wheels with twenty-four steps around a six-foot cylinder. Several prisoners stood side-by-side on a wheel, and had to work six or more hours a day, effectively climbing 5,000 to 14,000 vertical feet. While the purpose was mainly punitive, the most infamous mill at Brixton Prison was installed in 1821 and used to grind grain to supplement an existing windmill which Cubitt had previously installed nearby. It gained notoriety both for the cruelty with which it was used which then became a popular satirical metaphor.
The machines could also be used to pump water or power ventilators in mines.
Exercise treadmills
Over 100 years ago, there was an US patent of treadmill "training machine" (#1,064,968) issued on June 17, 1913.
The forerunner of exercise treadmills was designed to diagnose heart and lung disease, and was invented by Dr. Robert Bruce and Wayne Quinton at the University of Washington in 1952.Dr. Kenneth H. Cooper's research on the benefits of aerobic exercise, published in 1968, provided a medical argument to support the commercial development of the home treadmill and exercise bike.

Among the users of treadmills today are medical facilities (hospitals, rehabilitation centers, medical and physiotherapy clinics, institutes of higher education), sports clubs, Biomechanics Institute, orthopedic shoe shops, running shops, Olympic training centers, universities, fire-training centers, NASA, test facilities and training rooms of police and army, gyms and even home users.
Treadmill ergometers are now mainly motor driven. Most treadmills have a running table with sliding plate. Before and after the race table, there are two shafts. The running belt is stretched between the shafts and the running deck. Safety standards for treadmills are the IEC EN 957-1 and IEC EN 957-6.
For medical treadmills applicable norms, standards and guidelines are the Medical Device Directive (MDD), European Guideline 93/42 EEC, European Guideline 2007/47 EEC, IEC EN 60601-1, EN 62304, EN 14971 and the machinery directive 2006/42/EC.
Medical treadmills are class IIb active therapeutic devices and also active devices for diagnosis. With their very powerful (e.g. 3.3 kW = 4.5 HP) electric motor powered drive system treadmills deliver mechanical energy to the human body through the moving running belt of the treadmill. The subject is not changing his horizontal position and is passively moved and forced to catch up with the running belt underneath his feet. The subject can also be fixed in safety harnesses, unweighting systems, various supports or even fixed in and moved with a robotic orthotic system utilizing the treadmill.
Medical treadmills are also active measuring devices. When connected through an interface with ECG, ergospirometry, blood pressure monitor (BPM), or EMG, they become a new medical system (e.g., stress test system or cardiopulmonary rehabilitation system) and can also be equipped to measure VO2max and various other vital functions.
Most treadmills have a “cardio mode”, where a target heart rate is defined and the speed and elevation (load) is controlled automatically until the subject is in “heart rate steady state”. So the treadmill is delivering mechanical energy to the human body based on the vital function (heart rate) of the subject.
A medical treadmill which is also used for ergometry and cardiopulmonary stress test as well as performance diagnostics is always a class IIb medical device either when used as stand-alone device in a medical environment or when used in connection with an ECG, EMG, ergospirometry, or blood pressure monitoring device.
On the running deck the subject is moving, who adapts to the adjustable speed of the belt. The running deck is usually mounted on damping elements, so the running deck has shock absorbing characteristics. By a lifting element, the entire frame including treadmill running deck will be raised and thus simulates a pitch angle for uphill running. Some treadmills also have the reversing of a running belt for the purpose of downhill loads. Most treadmills for professionals in the fitness area, run for table sizes of about 150 cm long and 50 cm width, a speed range of about 0 ... 20 km/h and slope angle of 0 ... 20%.
For athletes, larger and more stable treadmills are necessary. Sprinters reach with some weight relief temporarily speeds of up to 45 km/h must therefore run on a large deck of up to 300 cm in length and have up to 100 cm width. At high physical exertion and increased risk of falling a fall stop unit is required to prevent a fall of the subjects or patients. This fall stop device is usually implemented by a safety arch on which a rope is attached to an electrical switch. A harness bears the subject preventing from falling and shuts down the running belt.
In treatment centers treadmills are used with built-in seats left and right for therapists, for example, so the therapists then can move the legs of a stroke patient in order to simulate walking movements and learn to walk again. This is called manual locomotion therapy.
Oversized treadmills are also used for cycling at speeds up to 80 km/h, for wheelchair users and in special applications with thick running belt for cross-country skiing and biathlon, where athletes perform training and testing exercise with roller ski on a running deck of up to sizes of 450 x 300 cm.
