Great product. Clean, do not need a lot
The secret stuff transforms from what feels like hand sanitizer to some of the most grippy chalk I have used, it lasted for a full workout that included push ups, and provided better coverage that I can usually accomplish with standard chalk. The next test was a kettlebell workout that was multiple rounds and high reps, it didn’t stay on the full workout, but lasted through a lot of reps. I also don’t have chalk all over the floor or my clothes, to get similar coverage from traditional chalk, I would be in a dust storm.
Very happy with this product. Friction labs really does make all the difference.
I’ve got really sweaty hands, like really sweaty. And while this isn’t the silver Bullet, it’s a massive improvement and helps cut down my use of messy chalk at the gym big time. Great product I will keep buying for sure.
