Product Review

Black Widow is an innovative liquid chalk formula specifically designed for CrossFit and functional fitness athletes. Chalk typically rubs off during a long sweaty workout. Not anymore. Spider Chalk's newest product, Black Widow, will last through an entire 20 min AMRAP, EMOM, or benchmark WOD and still have a dry, tacky feel. Like regular Spider Chalk, Black Widow uses laboratory-grade magnesium carbonate, the driest chalk on the planet but includes 2 bonding agents combined with a unique imported pine rosin that keeps the liquid chalk on your hand regardless of sweat or friction. We found ingredients unavailable in the US so we imported them. Real athletes tested Black Widow's formula for months with the results being the perfect grip glue for tough workouts.
