If you want to feel like a real badass at the gym, ditch your regular kettlebells for something a little more intense — Ironskull Fitness has upgraded the typical all-black equipment with designs to get your best workout.
While nothing says beast mode like an all-black skull kettlebell, options from Ironskull Fitness include camouflage and Frankenstein, and come in a variety of weights from 13-88 pounds. There's even a 215-pound Megaskull for the serious beasts out there. If you want to expand your kettlebell collection even more, check out these iron kettlebells with the faces of wild animals. Beast mode: activated.
