Do you know what a dip belt is?

The Dip is performed on parallel bars, by holding the body upright on locked arms (feet suspended in the air), then lowering and raising the body by bending at the elbows. It incorporates a wide range of musculature including the pectorals, triceps, deltoids and, unlike the Bench, requires a good deal of back strength as well.

Like Chins, the Dip is not simply a 'bodyweight' exercise. It should be performed progressively. In this fashion, a belt with a length a chain-link attached is used. The chain-link is fed through the centre of weight plates and is then hung around the waist, hanging between the legs. This provides additional resistance to the trainee's bodyweight. The belt used in this kind of exercise is called dip belts.

Dip belts are a very commonly used form of weight training. They are named for the dip exercise, one of the few and best known methods of adding resistance to it. It is also commonly used to add resistant to pull-ups and knee/leg raises in hanging from a pull-up bar. Unlike most weighted clothing, dip belts are not affixed to the body, but rather the weighted suspends semi-secured to the usually leather belt, suspending from the back and generally kept up by resting on the gluteus.

Dip belts are used to perform a dip, the exerciser hangs from a dip bar or from a set of rings with his arms straight and shoulders over his hands, then lowers his body until his arms are bent to a 90 degree angle, and then lifts his body up, returning to the starting position. Short people are able to cope better with a narrower grip, but not with a wider one. Tall people have greater ease in this exercise overall as their reach to body size ratio is greater

Classical weight lifting dip belts are made of leather. The belt’s width is variable. The narrow part is placed around the abdominal region and the wide one near the back. The belt's shape was designed so as not to hinder weightlifters while exercising (“snatch” and “clean and jerk”).

A dip belt can be used to add weight to exercises

As such, it is only useful in strength training movements, and not for dynamic movements, making it only pseudo-clothing. Dip belts are also used for added weight in squatting exercises, for people who want to work their quadriceps muscles with more weight without compressing their spine or straining their back muscles or hands. Due to the dangling length, these belt squats are usually done elevated, where the suspended weight will dip much lower than the feet, allowing a sufficient range of motion. How far below the feet it goes can determine the range of motion of the exercise, similar to limitations like squatting in a power rack for working heavy resistance near the top of the movement.

Wearing a dip belt also causes the lifter to be more aware of the position of his or her back. This is because the physical sensation of a dip belt against the skin provides additional information prompting the lifter to consider his or her back position and what muscles must be activated to maintain good posture. In this case, the belt does not need to be worn too tightly for an effect. Some lifters report feeling more secure and confident while wearing a belt even if IAP and muscle activity are unaffected.

Do you know what the best protective material is?

Kevlar is the registered trademark for a light, strong para-aramid synthetic fiber, related to other aramids such as Nomex and Technora.

Developed at DuPont in 1965 by Stephanie Kwolek it was first commercially used in the early 1970s as a replacement for steel in racing tires. Typically it is spun into ropes or fabric sheets that can be used as such or as an ingredient in composite material components.

Currently, Kevlar has many applications, ranging from bicycle tires and racing sails to body armor because of its high strength-to-weight ratio—famously: "...5 times stronger than steel on an equal weight basis

When Kevlar is spun, the resulting fiber has great tensile strength (ca. 3 620 MPa), and a relative density of 1.44. When used as a woven material, it is suitable for mooring lines and other underwater applications.

There are three grades of Kevlar: (i) Kevlar, (ii) Kevlar 29, and (iii) Kevlar 49. Typically, Kevlar is used as reinforcement in tires and rubber mechanical goods. Kevlar 29's industrial applications are as cables, in asbestos replacement, brake linings, and body armor. Kevlar 49 has the greatest tensile strength of all the aramids, and is used in plastic reinforcement for boat hulls, airplanes, and bicycles. The ultraviolet light component of sunlight degrades and decomposes Kevlar, a problem known as UV degradation, and so it is rarely used outdoors without protection against sunlight.

Kevlar is well-known as a component of some bullet resistant jackets and vests. Actually Stephanie Kwolek (born July 31, 1923) is an American Chemist who invented poly-paraphenylene terephtalamide—better to be known as “Kevlar”. It has varied uses and is being used by many diverse industries in world but our concern is its use regarding as safety clothing, especially in the areas which padding such as shoulders, back and elbows.

Lightweight and flexible it is, Kevlar has evolved over four decades of innovation and technology and it has all to do everything from helping to save thousands of lives around the world; making their ridings safer and better protected. If it needs to be light, strong and nonparallel safe, it must be “Kevlar”.

It is now being used for
motorcycle jackets. A Kevlar motorcycle jacket has a lot more merits than other riding jackets. Unlike Leather jackets they don’t give hard time in scorching summers, and are far safer in case of unexpected accident. Icing on cake is that these are easier to maintain, even easier than leather jackets. One would definitely need to buy a protection and cleaning solution to maintain and polish leather jackets. Leather jacket may also need professional cleaning once after some time but a Kevlar motorcycle jacket can easily be cleaned in a washing machine, any time.

Coming towards benefits of a Kevlar motorcycle jacket; for a polymer, Kevlar has very good resistance to high temperatures, and maintains its strength and resilience down to cryogenic temperatures like (-196°C); indeed undoubtedly, it is slightly stronger at bit low temperatures.

One of the first benefits of a Kevlar is that they're great to wear during hot weather. Other materials such as leather are too warm to wear when the weather is hot outside. Kevlar breathes better than nylon and leather, so they are more comfortable to wear during hot weather.


No one ever wants to face any accident while their riding. Unfortunately if you ever do down sliding on the asphalt while wearing any other polyester, you are likely to have permanent skin damage. Fact behind this general idea is that in actual polyester has a low melting range and poor abrasion strength, so because of the high fraction with ground/surface, it may melt into your skin, also you will be bruised all over.


And on contrary a Kevlar riding jacket is much safer to wear; beyond the words. It has high abrasion and fraction resistance strength and an extremely high melting range, so it won't melt into your skin; if something unseen and unfortunate comes……………….

Support your back by wearing weightlifting belts

Weight lifting belt is used in weight training. The purpose of weight lifting belt is to reduce stress on lower back muscles

Classical weight lifting belts are made of leather. The belt’s width is variable. The narrow part is placed around the abdominal region and the wide one near the back. The belt's shape was designed so as not to hinder weightlifters while exercising (“snatch” and “clean and jerk”). Generally, the portion of the belt that crosses the small of the back is approximately fifteen cm (six inches) in height.

Sometimes, lifting belts used in gyms are also called weight lifting belts. These belts can be of various forms and made of different materials

The belt is usually used in exercises where the lower back gets a heavy load, like a squat or a dead lift. There are mixed reviews regarding the usage of weight lifting belts. On one hand the belt decreases stress on stabilizer muscles, but on the other hand these muscles get less benefit from the same exercise.

A weightlifting belt has two main purposes. It reduces stress on the lower back while the person is lifting in an upright position and prevents back hyperextension during overhead lifts. A belt reduces low back stress by squeezing the contents of the abdominal cavity. This increases the intra-abdominal pressure (IAP), providing more support in front of the bones of the lower back. This allows the spinal erector muscles, which would normally provide this support of the lower back, to produce less force during the lift. Another benefit of increased IAP is a reduction in the amount of spinal shrinkage (lower back compression) a lifter may experience during circuit weight training. Some belts have a wide back and a narrow front. Therefore, it would be advisable to wear the belt backwards if increased IAP is desired, as the area gives the contents of the abdominal cavity more surface area to push against.

The belt prevents back hyperextension by forming a rigid wall around the lower torso, connecting the rib cage to the hip. This not only limits back movement, but it also prevents sideward bending and twisting. A power lifting-style belt that is the same width all the way around would be ideal for this purpose. Otherwise, a conventional belt can be worn in the usual manner with the wide part of the belt in the back.

Weightlifting belts can help support the back by increasing intra-abdominal pressure and preventing back hyperextension. They are most effective when used for maximal or sub maximal lifts in which the spinal erector muscles work against heavy resistance. However, many ill effects, such as high blood pressure and abdominal muscle weakness, may result from improper use of weightlifting belts. They should be used sparingly in training.

Wearing a belt also causes the lifter to be more aware of the position of his or her back. This is because the physical sensation of a belt against the skin provides additional information prompting the lifter to consider his or her back position and what muscles must be activated to maintain good posture. In this case, the belt does not need to be worn too tightly for an effect. Some lifters report feeling more secure and confident while wearing a belt even if IAP and muscle activity are unaffected.

However, a belt must be worn tightly to maximize its usefulness. This is physically taxing and should not be done for long periods of time. Research has shown that wearing a tight belt during exercise can elevate blood pressure. For this reason, belts should only be used on two primary occasions. The first is when performing maximal or sub maximal lifts in exercises such as the squat or dead lift, in which the weight is supported by the lifter's back. The second is while performing exercises, such as the military press, which may cause the back to hyperextend. The belt should be loosened to allow blood pressure to return to normal levels in between sets.

Suede leather

Leather is a material created through the tanning of hides and skins of animals, primarily cattle hide. The tanning process converts the putrescible skin into a durable, long-lasting and versatile natural material for various uses. Leather is an important material with many uses and together with wood, leather formed the basis of much ancient technology.

The material leather is one of the strongest materials used; it was so strong that back in the ancient days, leather was one of the key materials in making armors. Leathers may be strong, but leather have a very rough, which is why leathers are only used on furniture or other things, but there is a type of leather that can be worn.

Suede most commonly refers to a type of leather with a soft, napped finish; however, it can also refer to a similar napped or brushed finish on many kinds of fabrics. Suede leather is made from the inner splits of a side of leather, usually cow, although doe suede and pig suede are available. Because suede does not include the tough exterior skin layer, suede is less durable but softer than standard ("full-grain") leather.

Suede leathers are commonly used as pillow cases or most commonly are gloves. But suede’s are not only used by us, suede can also be used on dog beds such as the suede dog beds.

Suede leather is made from the under side of the skin, primarily lamb, although goat, pig, calf and deer are commonly used. Splits from thick hides of cow and deer are also suede but due to the fiber nature have a shaggy nap. Because suede does not include the tough exterior skin layer, suede is less durable but softer than standard ("full-grain") leather. Its softness, thinness, and softness make it suitable for clothing and delicate uses; suede was originally used for
women's gloves. Suede leather is also popular in upholstery, shoes, bags, and other accessories, and as a lining for other leather products. Due to its textured nature and open pores, suede may become dirty and adsorb liquids quickly. Suede should be cleaned as per manufacturer's directions. Modern tanning improvements have made waterproof and stain-proof suede leather available. Suede leather cord is a popular trim, lacing, and jewelry material

Suede fabrics are manufactured with a brushed or napped finish, resembling suede leather. Ultra suede is a trademarked term for a microfiber plush with a hand resembling the softest suede, but which is more durable, and can be made resistant to liquid, stains, and crushing. It is commonly used in upholstery and fine accessories, or in clothing and shoes. Persons who enjoy suede's texture but who prefer a non-animal product, or an easier-care fabric, find Ultra suede an expensive but luxurious alternative

Micro suede is a newly popular microfiber knit blend fabric; it has a soft finish, but is easily distinguishable from actual suede leather. It has a great deal of stretch, and is very popular in upholstery as well as garments. Micro suede is less durable than suede leather but is commonly found in accessories and especially shoes.
Suede silk, suede cotton and similar suede fabrics are brushed, sanded or chemically treated for extra softness. 'Suede' yarns are generally thick and plush, intending to resemble suede leather cord
