The best part is that the price is no indication of quality; there’s a reason they have thousands of five-star reviews. Thoughtfully made with sturdy cast iron, they’re durable and won’t crack or break after a couple of training 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. And, thanks to the clever hexagonal shape, these weights won’t roll around if you need to balance on them for a set of plank rows, or if you need to drop them for some burpees.
