The best part is that what they lack in price is no indication of quality. There's a reason they have thousands of five-star reviews, earning them the highly-coveted "#1 Best Seller" badge on the site. Thoughtfully made with sturdy cast iron, they're durable and won't crack or break after a couple gym sessions—though you wouldn't know it by looking at them. Each weight is covered in non-slip neoprene that's easy to grip and will protect your hands from calluses (there's nothing worse than ruining a fresh mani). And, thanks to the clever hexagonal shape, these weights won't roll away if you need to drop them for a squat sesh.
