Z Athletic Block Chalk for Gymnastics, Weightlifting, Rock Climbing, Crossfit (Multiple Sizes Available)

I use this for my reef tanks to build calcium for my corals, works good.

Great chalk

This chalk works well. But, it does not hold together real well, -as in using the chalk block to chalk the bar. It is very soft and super fragile and breaks apart while rubbing the block across the bar... But as a powder, it works very well. Personally, I like doing both in a gym setting. This does a very good job chalking and is far less messy. -some gyms get sick of the typical meathead making a chalk mess of the platform, etc... Then, they eventually ban all use of chalk! Good price, good product. Just wish the blocks were packed tighter and stayed together better.

Z Athletic Block Chalk is very easy to use! I am a beginner climber, the difference is night and day when you use this chalk compared to without. The grip is significantly enhanced, and I feel much more secure during my bouldering sets. I also love how long it lasts, and I don't have to constantly reapply it between routes. It's a decent size, but fits very awkwardly in a climbing bag. If you're serious about your training, it might be better to invest in higher quality chalk, but if you're a newbie like me, then this chalk should be sufficient!

My daughter recently got a gymnastics bar for her birthday and was so excited to start practicing. However, the bar is pretty hard on her hands, and we were looking for some chalk that she can use to practice in the house that doesn’t make a mess. I ordered this for her and placed in a plastic tote and it is great. The quality is just like at her gymnastics gym And does not make a mess all over. Would definitely recommend for anybody looking for great gymnastics chalk.

My favorite chalk so far! I like chalk that leaves the block easily and puts a lot on my hands and bar. Most chalks are too fine, leaving an almost slimy feel to your hands. This chalk comes off easily. 2 swipes across the block leave your hands thoroughly coated and gives a coarse, grippy feel, perfect for lifting or gymnastics. With this chalk I don't tear as frequently and I still keep a good grip. It's easy to use a lot of it which is wonderful! The block just doesn't last very long.

Great for my gymnast. We busted it up and put it in a chalk bag . The chalk feels good on hands to maintain bar. Great price and easy to bust up for a chalk bag

I order it every 2 months for my gymnast daughter; she loves it.

Sadly this product did not hold up to our expectation. It did not adhere to the gymnastics bar, and is made a very slippery surface. With use of this chalk, an athlete flew off the bar ☹️ I’m not sure if it is composed of the magnesium carbonate it should be. Sadly we have missed the window period for returning the product, as I had pre ordered in prep for the girls returning to gym.

Came early and it sounds great! Thanks :)

This was not a true product when it arrived. It completely crumbled and was not suitable at all for gymnastics use! I sent it back straight away but am still waiting for my refund
