We are the only manufacturer of gym and weightlifting chalk in the USA. Our process ensures that your blocks last longer, do not crumble, create less dust and grip stronger.

Top gyms across the USA use Spider Chalk Mega Blocks and they are now the standard for any weightlifter, powerlifter, gymnast or rock climber. We do not use fillers, binders or drying agents. Our manufacturing process produces a denser, cleaner and more pure block.

1. Lasts Longer - Pure chalk lasts longer on your hand and has better grip with superior drying ability.
2. More Dense - Our manufacturing process makes the blocks less brittle so they don't break into pieces and make a mess.
3. More Chalk - Spider Chalk Mega Blocks are 225 grams per block, 5x the density of standard blocks.
4. Pure Chalk - Other blocks use binders which turns slimy when you sweat. We use only magnesium carbonate.
5. Made in the USA - All conventional 2 oz blocks are made in the same factory and private labeled. We are the only chalk company who manufactures blocks in the USA and we're proud to make Mega Blocks at our facility in Atlanta, GA.
