DIY Concrete Dumbbell and Kettlebell Molds! The process is simple... we ship you an empty mold strategically sized to weigh an exact amount once filled with concrete. We will provide you with detailed instruction about what concrete to buy ($4 for 80 lbs of concrete) as well as the "mixing" process. It's time... for SELF-MADE GAINS!
