Plyo Box
A box jump being performed, onto a black plyometric box A plyometric box, also simply known as a plyo or jump box, is a piece of training equipment used for plyometric exercises. Plyometric exercises are a type of explosive power training that uses muscle elasticity to produce rapid, forceful movements. The plyometric box provides a stable platform for performing plyometric exercises such as box jumps, box squats, and box step-ups. Plyometric boxes are used by athletes and trainers to improve explosive power, speed, and agility. They are also used by physical therapists to help patients rehabilitation from injury. Design Plyometric boxes are typically made of wood, metal, or plastic, and come in a variety of sizes. The size of the box is determined by the height of the user and the desired level of difficulty for the exercise. For example, a taller person may need a taller box for a box jump, while a smaller person may need a smaller box for a box step-up. The box is typical ...

Box Jump Power Training
A box (plural: boxes) is a container used for the storage or transportation of its contents. Most boxes have flat, parallel, rectangular sides. Boxes can be very small (like a matchbox) or very large (like a shipping box for furniture), and can be used for a variety of purposes from functional to decorative. Boxes may be made of a variety of materials, both durable, such as wood and metal; and non-durable, such as corrugated fiberboard and paperboard. Corrugated metal boxes are commonly used as shipping containers. Most commonly, boxes have flat, parallel, rectangular sides, making them rectangular prisms; but boxes may also have other shapes. Rectangular prisms are often referred to colloquially as "boxes." Boxes may be closed and shut with flaps, doors, or a separate lid. They can be secured shut with adhesives, tapes, or more decorative or elaborately functional mechanisms, such as a catch, clasp or lock. Types Packaging Several types of boxes are used in packaging and s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plyometrics
Plyometrics, also known as jump training or plyos, are exercises in which muscles exert maximum force in short intervals of time, with the goal of increasing power (speed-strength). This training focuses on learning to move from a muscle extension to a contraction in a rapid or "explosive" manner, such as in specialized repeated jumping. Plyometrics are primarily used by athletes, especially martial artists, sprinters and high jumpers, to improve performance, and are used in the fitness field to a much lesser degree. Overview Plyometrics include explosive exercises to activate the quick response and elastic properties of the major muscles. It was initially adopted by Soviet Olympians in the 1950s, and then by sportspeople worldwide. Sports using plyometrics include basketball, tennis, badminton, squash and volleyball as well as the various codes of football. The term "plyometrics" was coined by Fred Wilt after watching Soviet athletes prepare for their events in track and fiel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jumping
Jumping or leaping is a form of locomotion or movement in which an organism or non-living (e.g., robotic) mechanical system propels itself through the air along a ballistic trajectory. Jumping can be distinguished from running, galloping and other gaits where the entire body is temporarily airborne, by the relatively long duration of the aerial phase and high angle of initial launch. Some animals, such as the kangaroo, employ jumping (commonly called ''hopping'' in this instance) as their primary form of locomotion, while others, such as frogs, use it only as a means to escape predators. Jumping is also a key feature of various activities and sports, including the long jump, high jump and show jumping. Physics All jumping involves the application of force against a substrate, which in turn generates a reactive force that propels the jumper away from the substrate. Any solid or liquid capable of producing an opposing force can serve as a substrate, including ground or water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squat (exercise)
A squat is a strength exercise in which the trainee lowers their hips from a standing position and then stands back up. During the descent and knee joints flex while the ankle joint dorsiflexes; conversely the hip and knee joints extend and the ankle joint plantarflexes when standing up. Squats also help your hip muscles Squats are considered a vital exercise for increasing the strength and size of the lower body muscles as well as developing core strength. The primary agonist muscles used during the squat are the quadriceps femoris, the adductor magnus, and the gluteus maximus. The squat also isometrically uses the erector spinae and the abdominal muscles, among others. The squat is one of the three lifts in the strength sport of powerlifting, together with the deadlift and the bench press. It is also considered a staple exercise in many popular recreational exercise programs. Form The squat begins from a standing position. Weight is often added and is typically in t ...

Bodyweight Exercise
Bodyweight exercises (also called bodyweight workouts) are strength training exercises that use an individual's own weight to provide resistance against gravity. Bodyweight exercises can enhance a range of biomotor abilities including strength, power, endurance, speed, flexibility, coordination and balance. Such strength training has become more popular among recreational and professional athletes. Bodyweight training uses simple abilities like pushing, pulling, squatting, bending, twisting and balancing. Movements such as the push-up, the pull-up, and the sit-up are among the most common bodyweight exercises. Advantages While some exercises may require equipment, most bodyweight exercises require none. For exercises requiring equipment, common household items (such as a bath towel for towel curls) are often sufficient, or substitutes may be improvised (for example, using a horizontal tree branch to perform pull-ups). As such, bodyweight exercises are convenient while travelin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dumbbell
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. History 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. A kind of dumbbell was also used in India for more than a millennium, shaped like a club – so it was named Indian club. 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. Etymology The term "dumbbell" or "dumb bell" originated in late Stuart England. In 1711 the poet Joseph Addison mentioned exercising with a "dumb bell" in an essay published in ''The Spectator''. Although Addison elsewhere in the same publication describes having used equipment sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbell
A barbell is a piece of exercise equipment used in weight training, bodybuilding, weightlifting, powerlifting and strongman, consisting of a long bar, usually with weights attached at each end. Barbells range in length from to above , although bars longer than are used primarily by powerlifters and are not commonplace. The central portion of the bar varies in diameter from 25 millimetres (0.98 in) to 50 millimetres (1.96 in) (e.g., Apollon's Axle), and is often engraved with a knurled crosshatch pattern to help lifters maintain a solid grip. Weight plates slide onto the outer portions of the bar to increase or decrease the desired total weight. Collars are used to prevent plates from moving outward unevenly so that the lifter does not experience uneven force. The barbell is the longer version of the dumbbell that is used for free weight training and competitive sports, such as powerlifting, Olympic weight lifting, and CrossFit. Many exercises can be done using th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weighted Clothing
Weighted clothing are garments that have heavy materials incorporated into them, to add weight to various parts of the body, usually as part of resistance training. The effect is achieved through attaching weighted pieces to the body (or to other garments) which leave the hands free to grasp objects. Unlike with held weights or machines, weighted clothing can leave users more able to do a variety of movements and manual labour. In some cases certain weighted clothing can be worn under normal clothing, to disguise its use to allow exercise in casual environments. The use of weighted clothing is a form of resistance training, generally a kind of weight training. In addition to the greater effect of gravity on the person, it also adds resistance during ballistic movements, due to more force needed to overcome the inertia of heavier masses, as well as a greater momentum that needs deceleration at the end of the movement to avoid injury. The method may increase muscle mass or lose weig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Push-up
The push-up (sometimes called a press-up in British English) is a common calisthenics exercise beginning from the prone position. By raising and lowering the body using the arms, push-ups exercise the pectoral muscles, triceps, and anterior deltoids, with ancillary benefits to the rest of the deltoids, serratus anterior, coracobrachialis and the midsection as a whole. Push-ups are a basic exercise used in civilian athletic training or physical education and commonly in military physical training. They are also a common form of punishment used in the military, school sport, and some martial arts disciplines. Etymology The American English term ''push-up'' was first used between 1905 and 1910, while the British ''press-up'' was first recorded between 1945 and 1950. Body mass supported during push-ups According to the study published in Journal of Strength and Conditioning Research, the test subjects supported with their hands, on average, 69.16% of their body mass in the ...

Dip (exercise)
A dip is an upper-body strength exercise. Narrow, shoulder-width dips mainly trains the triceps, with major synergists being the anterior deltoid, the pectoralis muscles, and the rhomboid muscles of the back. Wide arm training places additional emphasis on the pectoral muscles, similar in respect to the way a wide grip bench press would focus more on the pectorals and less on the triceps. Modern meaning To perform a dip, the exerciser supports themselves on a dip bar with their arms straight down and shoulders over their hands, then lowers their body until their arms are bent to a 90 degree angle at the elbows, and then lifts their body up, returning to the starting position. Variation Usually dips are done on a dip bar, with the exerciser's hands supporting their entire body weight. For added resistance, weights can be added by use of a dip belt, weighted vest, or by wearing a backpack with weights in it. A dumbbell may also be held between the knees or ankles.
