Leak-proof sand medicine ball
"This is the first sand medicine ball I have ever owned, though I have owned other traditional medicine balls, and I love it. I have yet to incorporate it into a workout, but frequently, when I walk by it in my garage, i do some cleans from the ground over my shoulder or even bear hug it and walk it back and forth a couple times. I have found no sand falling out and it’s no wonder why. There are so many different styles of closure on this that work together to make the sand stay put. Also, it can hold more than 70lbs of sand. I found this out when I filled it without a scale. At 60lbs is looses some of the rigidity it has at 70+ lbs but I think the irregular size will compensate for the lighter weight."
