History of Yoga Blocks

Yoga blocks are a common modern yoga item among the yoga and meditation groups. However, yoga was initially conceived as a spiritual act thousands of years ago, and its roots lay in Indian traditions, particularly the beliefs of Hinduism. Yoga is considered a form of spiritual growth, and thus, the original yoga blocks were made out of something spiritual, but something with the power to help spiritual growth. However, they weren’t made out of wood. Many of the oldest yoga blocks were constructed out of reusable materials, such as stones. Other yoga blocks are still constructed from stones, but are fashioned into different shapes.

In some historic cultures, stones were the most consistently available material to use for building yoga blocks. Ancient civilizations used stones as building materials, since they were sturdy and durable. They also smoothed into various forms easily, which allowed them to be constructed into many different shapes.

The most common stone used in modern yoga blocks is the "river rock." This type of stone is found in rivers along the coasts of the United States. This type of rock, is common and is easily formed into blocks. Yoga blocks have been made in the United States for around fifty years in the present day. Most of the yoga blocks used in the U.S. are molded from river rocks that originate from the upper Mississippi River.

EVA Foams

The majority of the yoga blocks you buy for home use will be made with EVA foams. This is because they are readily available and inexpensive, are lightweight and durable, and maintain their form over time without absorbing sweat and moisture from the skin. They also have a comfortable and soft feel.

These foams are widely used for blocks as well as other common items like shoes and packing material. They also often come in a translucent or translucent white color.

There are other foam block options that are also worth considering. Many yoga beginner kits include foam blocks that are supplemented with firm cushioning. Also, the blocks available at the most professional yoga studios will likely be made of soft, dense foam. This type of foam is much denser, supports heavier weights, and has a thicker feel to it.

Go to a yoga store or manufacturer’s website, and read some of the terminology used. For example, find out what the density is and what the density number means as you shop for blocks.


Cork is one of the most environmentally friendly yoga blocks. It is produced from the bark of cork trees. It comes from the layer of cork that protects the tree from drought and insects. Over time, the bark splits and curls and forms natural pockets called phellem. Cork is durable and firm so it is used to make yoga blocks, shoe soles, and furniture. Because of its durability, it doesn’t degrade and has a long life cycle.

If your old yoga block isn’t holding its shape, you can spray it with a food grade water-repellent and then put it in the freezer and then bring it out and let it stand for a few minutes before use. It should help re-fluff it. It is also not recommended that the person using the yoga block have a cork allergy or uses supplemental cork products.

One complaint about cork blocks is that they don’t have a sticky bottom. They have another layer of cork underneath the yoga block which makes them harder to hold. Some brands offer a sticky mat or rubber underside to help with that.


Most of the blocks found in the market are made with wood, wood powder, and resin.

The blocks made of wood are classic and still the most widely available.

Although they are easy to use because they have the right weight, they are not the best choices for beginners because they are slippery when your hands are sweaty.

While wood blocks are used by people of all levels, as your yoga practice level increases, you will need a stickier surface.

Resin is an alternative for wood, providing a stronger grip.

Problems you can face with wood blocks are that they deteriorate and stain with time, so it is better to keep them out of the direct sunlight.

The wood blocks are also good for people with sensitive noses.
