There are different factors about using an atlas stone that you should know prior to making a decision on purchasing one. The main thing to be looked at is the weight of the stone. If you are just beginning this type of training, you should start out at the lighter weight stones that you think you will be able to lift.
In order to gradually progress in strength, you’ll need different size molds in order to increase the weight. The type of mold chosen may also affect the number of molds that you will need. Here is a description of the two types of molds previously mentioned. This includes the pros and cons of each when it comes to making the stone.

These stone molds can be used to make multiple size stones. Depending on ones current level of strength, this will determine the size stone needed. There are multiple uses for an atlas stone concerning exercises that can be performed as well. Most think that lifting a stone is all there is, but there are other movements that can be performed as well. Here are some of these additional exercises that can be performed with an atlas stone.


Concerning durability, each of these stone molds are very durable in strength and are made out of a very hard plastic material.


When it comes to the quality of the product you will get out of each stone you make, this is similar for both brands of molds. Concerning the use of the mold in making the stone, the hybrid brand mold is much easier to use and does not require additional tools or work. Here are some short videos showing how to use these different molds. The main difference in these molds is that while the Slater brand requires more work, it has the option of using inserts which allows for a lighter or heavier weight using the same size mold. The hybrid brand of mold does not offer this, meaning you have to buy multiple molds. It is because of this option that I consider a Slater stone mold as being the better choice.
