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.
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 the barbell, such as bicep curl, bench press, Olympic weightlifting, overhead press, deadlift, and squat. Olympic barbells are usually an estimated weight of 20 kilograms (44 lb). Many fitness categories use the barbell for different reasons. For example, powerlifters use the barbell to perform compound exercise movements.
As a general rule, powerlifting requires use of stiffer bars to better accommodate the heavier weights being used in the sport. The deadlift barbell is usually the longest, thinnest and the most flexible, thus allowing more weight to be lifted. Powerlifting barbells use simpler, more robust bushings because they do not need to rotate as fast as Olympic weightlifting barbells. Sometimes the sleeves of powerlifting bars are also extended. Additionally, powerlifting bars have their grip marks spaced closer, at 810 millimetres (31.9 in). This closer spacing is used to check legal grip width in the bench press. Powerlifting utilizes the same bar for both male and female competitors.
The total weight of the barbell varies based on the type and number of plates loaded onto the ends of the bar and the lift being performed, and easily can be 540 kilograms (1,190 lb) or more with squat dedicated bar (which itself can weigh up to 29 kg (65 lb) and have up to 35 mm (1.4 in) grip section diameter).
This barbell was produced by the company Berg in 1910, but designed by Veltum. This was a major turning point in Olympic lifting as the barbell was able to revolve easily during the lift. After the Olympic games in 1928 Amsterdam, the barbells began to become popularized and many companies started to copy the barbell. The Berg barbell and copies of it were spread through many gyms around the world mainly from the 1960s to the 1970s because of the rise of the new barbell.
"Standard" or more commonly "One Inch" or "1 inch" barbells are characterised by a bar that is very approximately one inch (25.4mm) in diameter along the whole of its length, with a commensurate sized centre hole in the weight plate.
The main advantages of "Standard" or "One Inch" barbells and weight plates are that they are often easier to store and take up less room; the bars may come apart into two or three sections, weigh less, may also be convertible to dumbbells, and are usually much less expensive than Olympic weights for those on a budget. Weight plates come in cast iron, or coated cast iron, tri grip, or far thicker and cheaper vinyl filled with concrete.
Dumbbells are the equivalent of one-handed barbells, with a gripping surface approximately 16 centimetres (6.3 in) and a total length that rarely exceeds 50 centimetres (20 in). Adjustable dumbbells are the most prominent use of "standard" weight plates (those having a 27 millimetres (1.1 in) to 31 millimetres (1.2 in) center hole). Some dumbbell sets come with an attaching bar to convert the pair to a single barbell.
Originally known as a Dymeck curling bar after its inventor Lewis G. Dymeck, the EZ ("easy") curl bar is a variant of the barbell that is often used for biceps curls, upright rows, and lying triceps extensions. The curved profile of the bar in the grip region allows the user's wrists and forearms to take a more neutral, less supinated position. This reduces the risk of repetitive stress injury in these exercises. However, when performing the biceps curl, using an EZ curl bar prevents full contraction of the biceps, which can only occur with the wrist fully supinated, and thus may prove a less effective exercise.
Primarily found in gyms, these are usually fairly short bars with weights already attached and welded to the bar, and in some cases, a covering of plastic/rubber around the plates. A typical gym might carry a range of fixed barbells from 5 kilos (11 lb) to around 50 kilos (110 lb). They are handy as they take less space than full-length bars and are useful for many exercises where less weight is required. They can also provide an easier starting point for beginners before moving on to using the full olympic bars. In addition, they provide for speedy transitions between various weights if one is doing multiple weights in quick succession.
The present systematic review aimed to analyze the activation of the muscles involved in the barbell hip thrust (BHT) and its transfer to sports activities that include horizontal displacement. A search of the current literature was performed using the PubMed, SPORTDiscuss, Scopus and Google Scholar databases. The inclusion criteria were: (a) descriptive studies, (b) physically trained participants, (c) analyzed muscle activation using normalized EMG signals or as a percentage of maximal voluntary isometric contraction (MVIC) and (d) acute or chronic transfer of the BHT to horizontal displacement activity. Twelve articles met the inclusion criteria and the following results were found: 1) neuromuscular activation: hip extensor muscles (gluteus maximus and biceps femoris) demonstrated greater activation in the BHT compared to the squat. The straight bar deadlift exercise demonstrated greater biceps femoris activation than BHT; 2) Regardless of the BHT variation and intensity used, the muscle excitation sequence is gluteus maximus, erector spinae, biceps femoris, semitendinosus, vastus lateralis, gluteus medius, vastus medialis and rectus femoris; 3) acute transfer: four studies demonstrated a significant improvement in sprinting activities after BHT exercise; 4) as for the chronic transfer: two studies demonstrated improvement of the sprint time, while other two studies failed to present such effect. We concluded that: a) the mechanics of BHT favors greater activation of the hip extensor muscles compared to more conventional exercises; b) regardless of the variation of BHT used, the muscle excitation sequence is gluteus maximus, erector spinae, hamstrings, and quadriceps femoris; c) the acute transfer of the post-activation potentiation of the BHT is significant, improving the sprinting time; and d) despite training with BHT submaximal loads can improve sprint times, further investigations are needed.
Król, H and Gołaś, A. Effect of barbell weight on the structure of the flat bench press. J Strength Cond Res 31(5): 1321-1337, 2017-In this study, we have used the multimodular measuring system SMART. The system consisted of 6 infrared cameras and a wireless module to measure muscle bioelectric activity. In addition, the path of the barbell was measured with a special device called the pantograph. Our study concerns the change in the structure of the flat bench press when the weight of the barbell is increased. The research on the bench press technique included both the causes of the motion: the internal structure of the movement and the external kinematic structure showing the effects of the motion, i.e., all the characteristics of the movement. Twenty healthy, male recreational weight trainers with at least 1 year of lifting experience (the mean ± SD = 3.3 ± 1.6 years) were recruited for this study. The subjects had a mean body mass of 80.2 ± 8.6 kg, an average height of 1.77 ± 0.08 m, and their average age was 24.7 ± 0.9 years. In the measuring session, the participants performed consecutive sets of a single repetition of bench pressing with an increasing load (about 70, 80, 90, and 100% of their 1 repetition maximum [1RM]). The results showed a significant change in the phase structure of the bench press, as the barbell weight was increased. While doing the bench press at a 100% 1RM load, the pectoralis major changes from being the prime mover to being the supportive prime mover. At the same time, the role of the prime mover is taken on by the deltoideus anterior. The triceps brachii, in particular, clearly shows a greater involvement.
Given the lack of mass effect typically exhibited in PML this appears as a thin band between the abnormal regions, similar to a barbell/dumbbell. This should be discriminated from the enlargement of the splenium in other inflammatory or neoplastic processes.

Are you the person who has a barbell loaded with a set of 15lb plates, two sets of 10s, three sets of 5s and 2 sets of 2.5s? Not only are you hogging all the small plates in the gym, but you also look a little ignorant.
Trunk strength. The barbell row helps build trunk strength that carries over into other exercises and your daily life. You can enhance the exercise with a lot of weight, and it targets lots of muscles at once, which helps challenge and activate your trunk. A barbell row also helps promote spine stability.
To keep your spine neutral and stable, you need to hold your torso and contract your hips. All of this improves your hip movements, which can carry over into sports. Your hips help you generate force and power, so your coach or trainer might use the barbell row to strengthen these movements.
A barbell is a big investment. Aside from a squat rack and bench, your choice of barbell will likely be your most important gym equipment decision. It allows you to load weight onto your body, which means a reliable barbell needs to be durable and thoughtfully designed. Again Faster offers the Evolution Barbell, which we think is a great all-around pick. 781b155fdc
