Weight plateA weight plate is a flat, heavy object, usually made of cast iron, that is used in combination with barbells or dumbbells to produce a bar with a desired total weight for the purpose of physical exercise. Two general categories exist: "standard" plates, which have a center hole of approximately 25 mm (one inch), and "Olympic" plates, meant to fit on the 50 mm (two inches) sleeves of Olympic barbells.
PowerliftingPowerlifting is a competitive strength sport that consists of three attempts at maximal weight on three lifts: squat, bench press, and deadlift. As in the sport of Olympic weightlifting, it involves the athlete attempting a maximal weight single-lift effort of a barbell loaded with weight plates. Powerlifting evolved from a sport known as "odd lifts", which followed the same three-attempt format but used a wider variety of events, akin to strongman competition.
Olympic weightliftingWeightlifting (often known as Olympic weightlifting) is a competitive strength sport in which athletes compete in lifting a barbell loaded with weight plates from the ground to overhead, with the aim of successfully lifting the heaviest weights. Athletes compete in two specific ways of lifting the barbell overhead. The snatch is a wide-grip lift, in which the weighted barbell is lifted overhead in one motion.
DumbbellThe dumbbell, a type of free weight, is a piece of equipment used in weight training. It is usually used individually and/or in pairs, with one in each hand. HistoryThe forerunner of the dumbbell, halteres, were used in ancient Greece as lifting weights and also as weights for 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.
Strength trainingStrength training, also known as weight training or resistance training, is exercise designed to improve physical strength. It may involve lifting weights, bodyweight exercises (such as push-ups, pull-ups, and squats), isometrics (holding a position under tension, such as planks), and plyometrics (explosive movements like jump squats and box jumps).
CrossFitCrossFit is a branded fitness regimen that involves constantly varied functional movements performed at high intensity. The method was developed by Greg Glassman, who founded CrossFit with Lauren Jenai in 2000, with CrossFit as its registered trademark. The company forms what has been described as the biggest fitness chain in the world, with around 10,000 affiliated gyms in over 150 countries as of 2025, about 40% of which are located in the United States.
Biceps curlBiceps curls are a group of weight trainingexercises in which a person bends their arm towards their body at the elbow in order to make their biceps stronger, increase the biceps muscle size, or both. OverviewThe biceps curl mainly targets the biceps brachii, brachialis and brachioradialis muscles. The biceps are stronger at elbow flexion when the forearm is supinated (palms turned upward) and weaker when the forearm is pronated.StrongmanStrongman is a competitive strength sport that tests athletes' physical strength and endurance through a variety of heavy lifts and events. Strongman competitions are known for their intensity, pushing athletes to their physical limits. In modern strongman, athletes compete to score points based on their relative position in an event. An athlete who engages in the sport of strongman is also called a 'strongman'.
KnurlingKnurling is a manufacturing process, typically conducted on a lathe, whereby a pattern of straight, angled or crossed lines is rolled into the material. Knurling can also refer to material that has a knurled pattern, or the pattern itself. EtymologyThe terms knurl and knurled are from an earlier knur ‘knot in wood’ and the diminutive-le, from Middle Englishknaur or knarre ‘knot in wood; twisted rock; crag’.
Exercise equipmentExercise 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.
BodybuildingControl and development of musculatureBodybuilding is the practice of progressive resistance exercise to build, control, and develop one's muscles via hypertrophy. An individual who engages in this activity is referred to as a bodybuilder. It is primarily undertaken for aesthetic purposes over functional ones, distinguishing it from similar activities such as powerlifting and calisthenics.
HatchingHatching (French: hachure) is an artistic technique used to create tonal or shading effects by drawing, painting, or scribing closely spaced parallel lines. When lines are placed at an angle to one another, it is called cross-hatching. Hatching is also sometimes used to encode colours in monochromatic representations of colour images, particularly in heraldry.*As an Amazon Associate I earn from qualifying purchases.
