Real Chalk Feels Different

In 2016, Spider Chalk produced the first chalk block in the USA. How? We tried compressing regular chalk but the impurities made the chalk brittle. So first we had to create lab-made magnesium carbonate with increased capacity for moisture absorption which contained almost zero impurities.

With our newly created lab-made chalk, next we developed a revolutionary process of compression that was superior to the conventional method. Our results produce a cleaner, denser, dryer block that lasts twice as long as any other block on the market.

That's why Spider Chalk Super Mega Blocks are distributed in 21 countries and used in high school, college and pro weight-rooms along with gyms, Cross Fit boxes, and climbing facilities all over the world.

Voted the #1 Chalk Brand in 2020 in a survey of over 10,000 powerlifters, Spider Chalk remains the only chalk backed by scientific research with transparent lab results.
