If you’re looking to upgrade your home gym, the Hock Design Diskus Dumbbell Set ($14,700) might be the way to go. The set includes six pairs of dumbbells in weights ranging from 21-44 pounds, made from 303 non-reactive stainless steel. They sit pretty on a custom dumbbell rack made from sustainably-grown walnut that was polished and oiled to perfection. The dumbbell shelves were crafted using safeglide stainless steel to help protect your fingers from getting smashed.
