Concrete Weight vs Iron Weight – Which is best
Another difference between concrete and iron weights is that you can have a different type of iron plate that is designed to be dropped, and concrete is not. Whether you have a concrete floor, a drop pad, some rubber on the floor, it is never a good idea to drop a barbell weight as it can damage the floor, the bar or even injure yourself.
quick way to dry out sand?
Get a tarp and lay it out on the black top drive way. Pour the sand on the tarp in a thin layer, and let it set in the sun. Oh yes, try to keep the neighbors cats out of your sand box. To recover the sand, lift the edge of the tarp and move the sand to the middle where it can be shoveled out and into containers.
